You must listen to the teacher in class. Some ideas in college mathematics are completely different from those in high school, and sometimes they cannot be taught by themselves. Therefore, knowing all the derivation processes and ideas can definitely make you get twice the result with half the effort when doing the problem.

Secondly, it must be a problem. Do you want to learn math well but don't want to do it? It won't work.

I believe everyone knows the importance of advanced mathematics, college physics and postgraduate entrance examination. I am a slow learner. It may take me 1 hour to finish the homework assigned by the teacher, but the final exam score is 98, 100.

Listening to lectures carefully for two hours and doing problems after class are two things I have always insisted on in college, so my grades are not bad, but I am not a nerd.
