“Great instructor. He explained things well and I appreciated his passion for the subject. Liked the mock web content for practicing queries. When you moved into advanced queries, the pace went a bit fast- was still learning the significance of the basic queries and how to do them right. I was truly a beginner and the speed picked up a lot in the end. Would have liked more detailed instructions on what we were to do, and specifically what our project was to be. Like that I will have access to this and can go back and practice. Found it easier to work backwards- take the answers and deconstruct them. Appreciated all of the resources made available as well. Disappointed your web program crashed, hope it is made available so I can practice.”

“I didn't get to spend as much time in the class as I'd liked but Dan was very thorough and I recommend this class to anyone starting out with SQL and wanting to get a basic understanding of interacting with databases.”

“Very happy with the class. Taught in a clear and understandable way. Good introduction to SQL. I didn't join the live class as I am in the UK the time difference made the classes too late for me so I watch the recorded links. The negatives are that the sound on the 2nd lecture was very poor and the 3rd lecture seemed to get cut short but overall was $20 well spent.”

“Dan was very approachable and encouraged questions in class. The class is a great introduction to the fundamentals of javascript. It goes a bit fast for the complete beginner, but that might be the best way to jump into it. The class is mostly hands-on practice, which is fantastic.”

“Dan's enthusiasm for his subject was totally infectious and really gave the class a lot of energy. I think some parts were a little over my head (as a complete newbie), but Dan was very good at demystifying the idea of programming, and I'm totally inspired to learn more. If you, like me, know absolutely nothing about programming, I would just recommend doing a quick wiki refresher before class. ”

My only critique would be that I wish the class was longer. 2 hours isn't enough time to even scratch the surface on javascript. Other then that great class and awesome teacher!

“Dan was friendly, informative, and totally understanding of the fact that over 50% of us never had experience with programming prior to our class. He was patient, helpful, and great about giving us time to experiment and solve 'problems.' As he said, it is impossible to learn how to program in 120 minutes, but the class definitely offered participants the fundamental building blocks to move forward and expand our knowledge. It was exciting to learn a new 'language,' and I met lots of great people. I highly recommend taking this class and any other class Dan teaches!”

“If Dan offers additional Excel classes I will be signing up. Dan really is a master at Excel and is genuinely interested in helping others learn. He is a natural teacher, fielded questions like a pro, kept the pace just right, and even made us laugh a few times. Dan surprised our class with pizza and beer which was awesome but the study guide he gave us alone was worth the price of the class. Highly recommended!”
