But 36 problems are still not enough. And you don't take class, you don't have the homework. It's better to establish that habit with or without the class/homework. If you want to become good in chess, you have to practice (solving puzzles) everyday. Same logic for piano and math. That's the reason I created the video course of 5334, which is a two-year project. It will ask students to follow a schedule and do 6 problems everyday.
Now I am thinking about two courses focusing on solving problems everyday.
