(1) Pay attention to class, and notes are the key.

(2) Do your homework carefully. Think of several ways to solve a problem and do it every few days [this is the fastest way].

(3) review carefully and focus on the foundation.

(4) Ask if you don't understand. Don't be afraid. No one learns what you don't understand. You'd better ask the teacher. Classmates are only semi-finished products.

(5) Concentration is the best habit.

(6) Strengthen confidence, mathematics is not difficult.

(7) If you are stumped by a difficult problem, you should first make it easy and then difficult, overcome it wholeheartedly and never stop. How can I do without a burst of madness?
