Hey guys I was just wondering why there aren't practice problems for Number Theory, Mechanics, Computer Science, and Electricity and Magnetism. It would be really nice to have some so that people unfamiliar or weaker at some of the topics can have a convenient way of building up their skill. I am one of those people. Now, I'm not saying Brilliant should make practice problems because I can't get a textbook and become proficient at each one. I just think having the practice problems on Brilliant will be a nice addition and would make sense since there are already practice problems for Algebra, Geometry, Calculus, and Combinatorics. Please let me know what you guys think!
