What to do besides studying
Maybe there could be a course on what to do outside of studying, like obviously sleep is important but maybe things like what to eat during your 10 minute break and how often/long should you take breaks from studying, tips on balancing an already large amount of schoolwork/extracirricular activities with studying for the SAT. Theres probably tons of other things you could include in this that I haven't thought of but I think this would be a pretty unique and useful course if it was made.
