1. Go back to the textbook and see how these formulas and theorems are derived;
2. Do the case explained in the textbook again to see if it can be done;
3. Redo the multiple-choice questions, fill-in-the-blank questions and calculation questions on this semester's math test paper, check your ability to use basic knowledge and improve your calculation ability.
Mathematics is mainly to grasp the foundation, be familiar with the knowledge points, do more exercises, and at the same time make clear your review plan.
