Thanks Swathi for a well-guided class.  I enjoyed learning how to paint rain.  I started with 100% cotton cold press by Art Beek, but it dries too fast for wet on wet, so on the 2nd painting I switched to my favorite Arches 100% cotton cold press.  It seems to be the only paper I have found in the US that does good for watercolor.  I did not have some of the colors you used, so I improvised but that was not a problem.  I have a suggestion for you about tape, that I am going to put in the Discussions field.
