1. Introduction: welcome my course on the F 12 for beginners. My name is Byron. I've been a competitive speak uber for about the last 10 or 11 years or so, and I've taught well over 100 people during that time. This course is gonna directed towards those who already know how to solve the Cube. And you are interested in learning how to get faster and solve, like the pros, people who solved it in three seconds, five seconds. And you're interested in learning how they get their 1st 2 layers so fast here, I'm gonna be utilizing something that I like to refer to as an actual trainer cube and basically all the stickers a removed on that last layer and you'll be able to easily keep track of all these pieces as they move around the cube and you'll be able to make more sense of what I'm explaining to you. The best part is this is completely intuitive. No algorithms whatsoever are gonna be listed here. So with that being said, let's get started 2. Principals of F2L: So in order for you to start solving using F 20 you just have to understand a couple of basics. So first of all, we're always going to start our f too well, with our cross already solved like we always would, and you're gonna have the cross on the bottom. So as you are solving your F too well, you're going to be trying to look for what are called F 12 pairs and F to all pair is going to be a corner and an edge that have the same colors just like this. And when you insert them at the same time, solve that section of the Cube. So I have another cube here that's called an F to L trainer. And this eliminates the last layer distractions. So you can focus just on your cross and your 1st 2 layer pairs. So normally and beginners method, you're going Teoh, get your cross and then you're gonna get your corner, and then you're going to solve that middle layer one like normal now in EFTA well, where you solve the used to at the same time instead of them doing them separately. So, for example, if I had them separated like this. So I know these two are enough to well, pair because I have white, which is the primary color I'm solving for. And then I see here have read and I have green and I find an edge that has red and green. So I have those secondary colors taking care of. So that's how I'm able to identify these two as a pair amongst all the confusion when you're trying to solve in an actual scrambled cube. So once you once you identify those pairs, you're gonna pair them up and I'll show you how in a moment and then you're gonna end up with a solved F to L pair, and then you have to insert that pair into the slot all together. So that way you are able to knock out two birds with one stone using this. So as the cube is scrambled, these individual pairs are going to be mixed up all over the place and you have to locate them. You may have to split them up if they're an improper pair. And what I mean by that is this is a proper pair where these colors match this color matches. It's nice and nice and organized. And then what is considered not a proper pair? It would be something like this where it's still a pair, but it's improper. And in normally in this situation, you have to break the pair up. You have to pair them up and then put them in the correct slop. Now, I'm going to explain exactly how I go about all that. But the first thing you have to understand here is exactly how this works, what you're kind of looking for in F too. Well, and you're just looking for these f to l pairs. You're finding a corner and find its corresponding edge, and you're trying to insert it. So now that you understand what an F 12 pair is, it's gonna be a little bit easier for you guys to understand what I'm gonna be explaining next 3. Basics of Empty Slots: so one of the good things about F 12 is that there are no algorithms that you have to learn . This is completely intuitive. You could go there out of learning the algorithms for all of the over 100 cases that there is. But you don't have to because you can do all of them pretty intuitively. It's actually really cool. There are some special cases you may want to get algorithms for in the future, but until then you can do all of the cases completely intuitively, and we're gonna go over all of that now. So what you want to understand is when you have any NF two, well, pair together like this. You have a three or they call a three move insert. When it's in this position, it's when you open the door, you step in and you close the door that could be translated to left, inverted up, left and then you also have a similar case on the right hand side, where you have your actual pair and you're going to insert it into its correct slot. And you know this is the correct slot because you have blue and orange and you have blue and orange, so it belongs here, and you're going to open the door, step in and close the door, or right up inverted, right, inverted or prime whichever one you like to go with. So now that you understand that, now we're going to understand the next one, which is when they are separated. This particular cases, whether separated and they have opposite colors on top when they have opposite colors on top. It's another easy three move insert, and this is where you're going to go towards the edge, bring it down and bring it down that just like that, or you're going to do left, inverted up, inverted left. Similarly, we have the mirror of that case, which is going to be right up, right, inverted that brings that one down and then you will run into a case. It's a little bit different like this, where if you try to go towards it with opposite colors, it does not pair of. So in order to fix this case, we're gonna go over something called empty slots and empty slots is going to be something like this. It is mixing it up a little bit so that way I can show you guys so an area that is not solved, so I'll show you one that solved. This is a solved slot, and anything that is not solved is considered an empty slot. You're going to utilize these empty slots to make these F too well pairs. For every F to L slot, you have 44 F two else lots. You have one that's solved right here. 123 and four. So it's four slots. You can utilize any of these empty slots, and this top layer is your working area. You don't care what's going on up here as long as the two pieces that you are currently working on or in this top layer. So how to utilize these empty slots is going to be discussed in the next video. 4. Different Colors: So we're talking about empty slots. Now, an empty slot is gonna just basically gonna be a corner in an edge between your to cross pieces that are not solved or even if it's partially solved. It is not completely solved. Then we're just gonna consider that. Sorry, I would change my focusing. We're just gonna consider that on empty slot. So you're gonna use these empty slots to pair up your F two l's. So here's what I mean by that. So I have this corner and actually, I'm going to, uh, solve all this, make a little bit easier to see. So I have this corner in this edge that belong here in the corner is above the slot. It belongs. They're opposite colors. So if I brought the corner over here, they would pair up. They'd make enough to a pair, I could bring it in, bring it down. This is one of those basic cases that I explained earlier when you have a three move insert , but you will run into a case where you try to do the same thing, but they don't line up, it doesn't work. This is because this edge is actually supposed to be over here in order for this to work. So if you triangle like this and that just doesn't line up and their opposite colors on top , that's telling you that the edge needs to move. So if the engineers to move over here, we just turn it like that, right? But the corner moved with it, so they are still in the same position in relationship to each other, so I still can't do anything. So what we have to do is hide the corner of the edge and then move one of them. Ah, certain direction. So we know this edge needs to move counterclockwise one spot. So what we're gonna do is try and take this corner out of this top layer so we can move this counterclockwise one spot. How we do that is by utilising empty slots. So we have an empty slot right here, the one that the corner is directly above. If we set the corner here, we can actually bring it down and bring this empty slot up to the top layer. And now we can freely move this top layer around with keeping the corner in the same position so we needed to move this counterclockwise one position, so we'll do that. And now we'll bring the cornerback, bring the corner above where it belongs. And now we have our regular three move, insert. So here's the case again. We're gonna bring the corner, and this time we're gonna bring it this way. We're gonna hide the corner, move the edge over. Bring the cornerback and we have our three move insert, and this is gonna be mirrored the same way for the right hand side. So here, same thing. Can't get that to work. So we need to move this over one. So we're gonna hide the corner just like that, In case you didn't see brought the corner over here. Brought it down to bring up that empty slot. Move it over one. Bring the cornerback. And now we have are three. Move, insert nice and simple. So this is one case you have the regular three move, insert and then you're gonna have the one where it's not that easy. And you have to set up a different case and we'll get you basically have to do some set up moves to get to that three move, insert. So you have this normal case that you just bring it in like that same thing on the other side, where you have your solved after welfare and you bring it in. And then you have your regular three move insert for the left and then your regular three move insert for the right. So these are gonna be the basic inserts, and you're basically gonna be setting up these other F to all cases that are improper is what we would call them. You're gonna be setting them up for one of these three insert cases or simple cases, and I'm gonna be explaining the next case in the next video. 5. White on Top Case: so I'd like to encourage you guys to grab your cube and go ahead. And I would say follow along or try and look at your cube and try and pull up some of these cases that I'm explaining and see if you can knock out some of these F two wells yourself. Now, keep in mind this is going to slow your time down significantly because you're learning this. But with practice, you're going to just blaze the cube. I am at the point now. I'm doing my whole cross and 1st 2 layers in somewhere around, um, 10 seconds or so, so you can get really good times with this. And this is the same method the pros use. So the next case I'm gonna show you is when you have white or whatever your primary color is that your crosses that your corner is showing on top. You're going to address this case the same way all the time, as long as the F to L pair you're looking at are separated. If you have white on top and they're connected, it's a different case. So you're going to want to hide that corner to move that edge in order to set up the correct case that I'm about to show you now. So if you run into this, all you have to do and it's really easy is your going toe line up your edge side color. So here the side color is red. So I just got that lined up and you're going to move the edge away from the side. It belongs to. So here the top color is green and the green side is here, So I'm gonna move it away like this. Then you're gonna put your corner and put it on top of that edge, and then you have your F 12 pair. We're gonna fix our cross, and there's your after well pair. Now we have just set it up for one of our normal simple inserts where you're going to step it aside and we're gonna drop it in where it belongs. There you go. So this is going to be the same case regardless. White on top, line up your edge, put the corner on top and insert it. It will be the same thing here. Actually, I'm gonna show you. Ah, slightly different case. It's gonna be same case. Just look a little bit different. So here, white stickers on top, but my edges in the middle layer. So there is a really, really fast algorithm for this, but I'm going to explain this intuitively for you. So when you run into a case like this, we just have to get the edge in the top layer separate from the edge are from the corner. So way we can do this is we can bring the corner here and bring it down, bringing the edge up. Or we could even bring the corner there and bring the edge up like that. Move it. And there we go. Now we have white on top. So first thing we're gonna do, line up our edge, put it away from the color it belongs. Line up the corner on top, fix our cross, and there's our f to l. A pair. Then we just inserted like normal. So keep in mind, this is can also happen on the right hand side. So here I have white on top. This belongs here, and I'm gonna get that lined up. Go away from the color it matches, place it on top. Fix my cross and there is my F to welfare and then just insert it like normal. So now that you understand that, then we're able to move on to where we have both pieces improper in the top layer. 6. Improper Pairs: Okay, so you're solving your cube and you have the situation where you found your f to a pair. But they are together, improperly in the top layer. So what we can do here is we will. The priority number one is to separate them. If they're together like this, there's nothing you can do unless you separate them first. Then you can set them up to be combined into a proper F to L. A pair. So first thing we're gonna do here, separate him. The way we can do that is we can bring this empty slot up which will separate the two like that. And then we could just move the corner out of the way and then fix our cross. Now we have them separated, or we can go like this and we can put the edge in the middle layer, bringing up this empty slot, move the corner and then bring it down. Separated now. So there's any ways that you can do it. And when the cube is mixed, So like here, let's say thes two are an improper pair right there. So I'm doing green and orange, and there's green and orange and it belongs right here between green and orange. Belongs right in there. I can separate these two because I have an empty slot back here. I could just bring the corner down just like this and move that edge over. So now they're separated. Or I could have it where I have both of them back here. And I could move the corner like that and do that because I had an empty slot right here. So any time you have an empty slot, you can do this. So, for instance, here I have a solved slot right here, so I wouldn't be able to put the causes The parrot here, I wouldn't be able to put it back here and hide the corner. I would bring up a solve slot, so I can't do that. But what I can do is bring up this empty slot and hide this corner like this and move the edge. Now they're separated pair, so keep in mind where which slots you're bringing to the top layer, cause that's really going, Teoh make things a little bit more difficult for you if you're bringing up things you've already solved previously. So here's another So here's the example There, together, improperly, I'm gonna bring up an empty slot or do something to separate the two. And then that's gonna give me one of these cases. So the new case I'm going to be showing you guys is one that you have the same colors on top when you have the same color on top. If you notice I'm going to do it in this at this angle, if you notice here If I were to take this edge and move it over here like that, it would be read on top and it would be blue on the side, so this would turn into a proper F too Well, pair. So I just need to move this right next to it in order to do that So I can do that by bringing this empty slot in the top layer in hiding this corner, but leaving this edge right here in the top layer so I can bring it down like this, and then I just have to move it over one. So when I fix my cross, there's my f to l. A pair. I just paired them up, and now I can insert it like I normally dio. So here we go. Here's another case. It's a little bit mirrored, so same colors on top. So this just has to move over right there. If I bring my corner over here and try to hide it, that edge is gonna go with it. So if I were to bring it right there next to it, that's an improper pair. So I need to get it where this edge stays in the top layer as I hide that corner and I can do it by placing it here and hiding it. Then that stays in the top layer. Then I just could move this over. So when I bring it back up, there's my pair and then I can insert it like normal. So now we understand. Three of the F to all cases were more so probably four f to all cases. And that's gonna cover the vast majority of F to all cases you're gonna run into. And I'm going to cover one more case, which is where they're both improperly. Ah, improperly combined in the bottom layers 7. Improper Pairs 2: So in order for you to solve this F to L. A pair, you have to get both of them in the top layer, preferably separated. And then you can combine them properly and then insert them using one of the easy insertions that we've learned before. So here we have, ah, messed up f too well, pair that's in the bottom layer. Or that's in the bottom two layers so we can take them out like that for where you can take them out like that, which is a bit more efficient because using well, what we do here 123 in order to take that out, or we can take them out like this. 123 and we've separated them doing those moves. Now, as you're learning this, this isn't something you really should be worried about as far as how efficient you're doing it. That will come in time. But let's see, I took it out like this. Now I have to separate them, and I can do that by bringing this empty slot up and bringing this edge in the middle layer , keeping my corner in the top layer, and I can move it and then fix it. So now I have one of the cases we went over before, matching colors on top. This edge has to come right here so I can hide my corner, leaving that in the top layer and then just move that over so I could hide my corner like this. Bring my edge over on hide my corner and there's my half to welfare. Done. I'm gonna show you guys another case. So here, this is not right. So we have to take this out and separate them because they're improper. In order for us to put them back together properly, we have to separate him. So we can either bring them out like that to bring into the top layer, or we can bring them out and separate them by doing that, which is the more efficient way. So now we've brought it up this way. What we're going to do is look at the top colors and see what case we have. We don't have white on top, so we know we don't got that. We don't have mismatching colors on top, so we don't have that case. So matching colors on top tells us when you to bring the edge around next to it. So the side that doesn't have white which is this this side that edge needs to stay in the top layer when we hide that corner. Because if you notice if we bring this edge over here, is gonna be read on top and read and read and got a match. That's good. But blue is on the side. Blue and white are not gonna match. But if we have it on this side, it will be a perfect after welfare so we can bring the corner aside. Hide it, bring the edge over, Um, hided it, There's our after well pair insert it like normal. So now let's spice things up a little bit and we're gonna focus on two. Have to well, pairs now. So I got to f to l slots solved, and I have to f Tual slots scrambled. So let's start with one. I'm gonna start here. This is a red and green a corner, and I have to find its corresponding edge, which is right here. How do I know it's red and green? Just the secondary colors of the corner, Like the case I have is white on top and they're already separated. So now the protocol for this would be tow line up the edge with the correct color, then place the edge away from the side. It belongs. There's right on top. There's right here. So I'm gonna bring it over to the Orange side because it belongs. It's gonna go the away from where it belongs. Place the corner on top of the edge like that. Then fix my cross. There's my F two. Well, pair. Now I'm going to insert it. And this is my next pair. This is an improper pair. So first thing I need to do is split them up so we can split them up like this. Bring up this empty slot, move that over twice, and keep in mind when I bring that when I split them up like this and I bring this up and move it over twice. If I move it over once, he would bring that down to the bottom layer. And I don't want that. That's why we move it twice. The case I'm presented with is matching colors on top. I have to bring this edge to the side of it, and I can do that by lining it up like this, hiding my corner, bringing that over on hiding. And there's my have to welfare get inserted like normal. So now in the next video, I'm going to do an example solve on this cube where it's completely scrambled. 8. Trainer Example Solve: so to save time, I've already taken care of the White Cross. So now the white crosses done. We're gonna set that down and we're gonna locate our first F to a pair. Now, keep in mind, I scrambled this entire thing. So what we're gonna first do is we're gonna locate our first corner. This one's right here. Sums going to use this one. Now I have to find its corresponding f to l pair edge. And this one is blue and red, so I'm gonna locate blue in red. Now, if you look here, there's nothing. No information here. No information there. That's not blue and red. That's not blue or red. There's only one other place it can be back there. This is what we kind of understand as what's gonna help us with? Look ahead in the future yet again. Don't really work. We worry about that now. That will come later. But now that I have it down here, first thing I have to do is get this in the top layer. I can do that by bringing it up like this. Remember, this is our piece. We're gonna keep track of these two. I'm gonna move it over and then I'm gonna fix the cross. So these were the two that I'm working with the case. I have opposite colors, so I know if I bring my corner that way, it's not going to work. So that's telling me I have to move this over here. Now, This isn't the case that you bring it next to it because then we'll be opposite colors and this is an example. They would be opposite colors, so I have to bring it away from it. It's the way I can do that. Hide the corner, move the edge over one slot. I have an empty slot right here, so I could just hide it just like this. Move it over. One on hide. There's my simple case now, in order for this to work, if I go to it and go like that and bring it down, it's in the wrong slot. So I have to bring the corner above the slot. It belongs. Then I can do my easy case to solve that to one of four F two. All slots are completed. Now I'm gonna find my next f too well pair. I see this one. I'm gonna run with it and I have its corresponding edge back here. This is blue and orange, and this is a blue and orange. So first thing I'm gonna dio established what case I have, I have the white on top case. This will tell me. Tow line up my edge. Side color, move it away from where it belongs. Place the corner on top of the edge and then fix my cross. There's my have to Well, pair now I can insert it. There we go. Next case. I see this one and this is one of those ones that Ah, you can look up an algorithm for it. That's very easy. But for simplicity's sake, I'm just gonna explain it very intuitively. So my battery's about to run out, so let me change that out and I'll pick this back up. This case that we have here is going to be where we're going to separate the two, and then we're going to pair them up properly. So the way we can separate this utilizing our empty slots is now that we have two that are filled, we only have to to work with now So the best way to go about this could be where I could turn it, hide the corner and move it over. Or I could from this angle, lift it up like that, moving over twice, fixed my cross. Either one will separate it. Whatever floats your boat that you really can just do whatever you want. So I'm gonna established the case that I have matching colors on top. So I need to bring this edge around two of the side. So I'm gonna hide this corner so I can move that edge over. I can do that by placing the corner here, bringing up this empty slot by hiding it like this. Move that edge over There's my pair and then I can insert. There we go. We got one more to go. 9. Trainer Example Solve Finish: So in this last case that I left off on, we're gonna establish our case. White on top says, line up your edge, moving away from the color it matches, place it on top, fix your cross. There's your pair nice and simple. So we've basically covered all of the cases that are required. There are some cases that require that not require, but that you want to learn algorithms for for example, I would say something like this. This would probably take a long time to figure out. But there is a very fast algorithm that can just kill it. So we're going to actually start working on doing a full cube with the added distractions. Now we're gonna get rid of the trainer. So I think you guys are pretty good now. Or at least you should be so far. Feel free to just rewind, re look at all the cases and memorize exactly how to go about him. So that thing that it's jobs and now we're going to start working on this, we're gonna establish our cross, and then we're going to start working on our F two wells just like a real solve 10. Full Example Solve: So keep in mind, you guys, none of this is staged or anything like this is completely random. Scramble. So I got my cross taking care of, and now we're going to start our after wells. So first corner I see is this one and this is going to be blue and orange, so gonna locate its edge, which is right here. And this is what we call an improper F to a pair. There is an algorithm for this that's very fast. But for simplicity, state simplicity's sake, we're not going to use that. So I'm going to bring this edge up in the top layer, making sure it is not connected to this. I can do that by moving this over and then I can take that edge out and fix my cross. And there's what I got My case States white on top, line up my edge. Side color, top colors orange. So I'm gonna put it away from the color it belongs. Place my corner on top of my edge, fix my cross, and there's my pair. Then I can insert it just like that Next case, these two. So these two or this is actually very easy case corners already above where it belongs. And because it's an improper pair, I have to split them up first. So if I were to split them up like this, I can actually absolutely do that. Move it over because I have an empty slot in the back that I can utilise because nothing that's in here matters nothing really don't care about anything that's back there. So I could hide my corner like this. Move my edge over and unhygienic. However, with this opposite color case like this, if I were to bring my corner over like I would expect to do, that doesn't line up. So I sent the case back up here. So from experience and from practice, I know I have to move this edge over here instead of just moving it over once. So when I hide this corner, if I move it over twice and then bring it back, I have a perfect three move insert right there, and that will come with practice. You'll be you begin to start to see that next case, this corner, this edge. So protocol says I have my white on top line up my edge and then I'm going to place it of the color. It doesn't match. Place the corner on top, and I'm gonna fix my cross, and I'm going Teoh, insert that after. Well, pair. All right, last case. And this is actually just our regular three move insert. They're already there. They're already ready to go. So just like this done, F too well is complete. So I'm actually going to do a faster walk through, Not necessarily expecting you guys to keep up, but just so you can really see how fast will not how fast but that this can really get you . So keep in mind, I don't normally solve white, so my recognition is not that great, but here we go. I see these two whites on top line it up and I inserted that these two right here I can knock these out with an algorithm that I learned that's gonna be more for the advanced of 12 people. I'm gonna be putting a video out for that too. So stay tuned and follow me. So that case is taken care of. These two, right? Here are a pair, and I can do this rotation list. I can insert that in the back. So I'm gonna move this edge over cause I already know that that's not gonna work. So I separated him there. Right in there. So now I saw that this is another one that you can learning algorithm for, for advanced F too. Well, this is a really easy case, but basically, I'm going to move the corner here, hide it, turn it twice, bring the cornerback, and that sets me up for my three move insert. And then that's it. It has already done. You can knock out actual incredibly fast. This is the same method that people that solve in three seconds, four seconds the world record has been set using this. So the sky's the limit. Really? And I'm gonna do one more example. Solve. Just another walk through. Of course. Look at it if you want. Of course, you don't have to, if you're are already understanding it. But you can learn so much with actual. It's insane. I've been cubing for, like, 11 years, and I'm still learning stuff about this. So, uh, in case you're departing me at this point, please follow me. I'd like to get a review on the videos. Let me know if you guys learned anything and stay tuned for the advanced F 12 video I'm gonna be putting out pretty soon. Thanks. 11. Final Example Solve: All right, you guys. So I am going. Teoh, post the scramble up here, actually, pull this down. Scramble will be up here, and this is gonna be with yellow on top blue in fronts. That way you guys can follow along. I'm gonna be doing White Cross, White Cross. First thing I noticed that these two I can easily just move over. Just one turn, and those two will both line up, so that's really cool. And then I noticed I can actually knock this out. Really? Cool. This I can bring up here so I could turn it up and then bring it down here, and that will be solved in relationship to the others. And when I do that, this green one will come down, and I can just put it there and knock them all out with that last turn so I can just do this and then one turn, and that will take care of everything. Really, really nice cross. So first thing I see is on the green and red. I see this white sticker on top. I'm gonna find its edge, Which, from what I can see here, it's probably back here. Yep, So I'm gonna bring this up like this, and then I'm going to line up my edge because I have the white sticker on top and I'm gonna place this away from the side. It matches, place the corner on top, bring it back. There's my have to welfare and then I'm going to insert that like, normal. And now I see this one. I'm gonna find its edge, which should be back here. I'll wait here. Uh, next Miss that up. So now, matching colors on top. I'm supposed to move this next to it so I can do that. I can either turn it twice and hide the corner. Bring the edge over that way are gonna have the corner here, hide it this way and move it over there. But if I have it here and I go down, I'll expose a solved slot and I don't want to do that. So I have to either do that or the other method that I was showing. So this one's already here. Let's not get out this way so I can hide my corner like this and bring this over. Now, remember, I'm using it. Uh, unsolved slot or an empty slot, so that's fine. I'm gonna move this over on hide my corner. There's my F two. Well, pair and I can insert those two. Now, I'm gonna find another one, which I see this one right here. And I found its corresponding edge right there. We have matching colors on top, so I'm going to do the same thing I did before and move it over. But I can't hide the corner like this cause I'll expose assault slot in the back so I could either hide it like that and move the edge over, or I can hide it like this and move the edge over So we'll just hide it like this. Move that edge over and now insert it like normal. So this is another case that you can get an easy algorithm for, but for simplicity's sake will not do that. So it's an improper pair, so I need to split them up first to get one of the cases I recognize so I can split them up like this. Turn it twice. It fixed my cross and there we go. I have a nice, easy three move insert, and there's F 12 and that is basically it. I'm trying to think of any other cases that I could possibly run into, and aside from any weird cases that were there, were there improperly paired. That's basically it advanced. F 12 will basically take some of the harder algorithms or harder cases that you'll run into that require a lot of time and a lot of moves to do. And it just simplifies it to the most efficient algorithm possible in order to make it really, really fast for you to knock that case out, especially when things like don't require rotations. But you guys will definitely like that when I decided to bring that out. So I'll probably give you guys a week or two before I start throwing that out there. But definitely practice makes perfect. If you guys were interested in picking up this cube, the actual trainer I did, which is basically a cheese sale, that I just peeled the stickers off the top layer. That's all that is, or even this beautiful Matt, which I am currently reviewing. I absolutely love this matter. Oh my God. So you guys are more than welcome to go to the description for the course, and I'll have links posted where you guys can pick up everything, including the lube that I use for this que to make it so frickin fast. I love this thing. That's awesome. But I would like it if you guys followed me. Stay tuned for the actual advanced F to all I'm gonna be putting out as well as review the course. Please. I'd really appreciate it. And I'd like to hear from you guys. I'll see you next time. 12. Congratulations!: So if you guys are seeing this video, that means you've reached the end of the F 12 course. Congratulations on picking up this new skill. It's gonna take time. You're not gonna be fast right out of the gate. As I like to say, You're going to get slower before you get faster. So definitely practice it. And you're gonna start running into the same cases over and over and over again, and you're gonna end up developing a recognition faster recognition toe Handle those cases . I do have a new video. It's coming up. Called Advanced F 12 should already be up by the time you reach this video. And that's going to be covering more complicated cases. Kind of like this midst mitt mismatched pair right here and showing you a very efficient, effective way to take care of that case. There's gonna be very fast ways to go about all of these complicated cases, and I'll be addressing a lot of those in my next video. So when you guys are feeling like you're ready to move on, go ahead and take a look at that of one of my courses and then we will move on from there. The next courses after that one I'm gonna be posting will be dealing with the last layer, and we're gonna end up knocking that out as well. Go ahead and review the course, and I would really appreciate it. Or at least let me know how I'm doing. If I'm doing anything good doing anything bad, I really appreciate to hear from you guys and I'll see you guys in the next video.
