Math problems can't be finished. For second-year students, doing a lot is just not enough! I feel that I didn't do anything in the exam. I didn't have time to come out even after careful consideration! What to do? First, believe that you can do it first. Second, don't be eager for quick success and instant benefit, do every problem, do it thoroughly, and seek improvement without asking for more. Third, familiarity with teaching materials is the key. Fourth, do simple questions first, step by step from shallow to deep. Fifth, summarize the problem-solving methods of each question type (the typical teacher will talk about it repeatedly, pay attention to remember). When you see every problem, first look at what conditions you need, then figure out what conditions you can have, and then sort out the thinking of this problem. It's usually like this. What the teacher said in the exam, pay attention to recite what the teacher said. I believe you can.
