Actually, to tell you the truth, I used to be a math class representative, but I think we should calm down. Now we don't do well in math, and we don't have to do problems all day, so the most important thing when doing problems is to sum up experience, make every problem clear and learn every knowledge point well. In this way, you will get high marks.
Remember, there are not many topics but good ones.
I wish you progress in your study and have a good mood every day.
