First, make up math during the holiday, learn the basic methods of learning math as soon as possible, and make up the rest of math knowledge;

Second, preview before class, know what you may not understand in this class, and pay attention to it;

Third, do more exercises. If you understand in class, you can only say that you know110, and most of the others can't, so you should consolidate, expand and improve the content of the textbook by doing problems.

Do the above, I believe you can learn math well.
