When you encounter problems that you can't do in the exam, you must put them aside and do them first.

Some questions you are not sure about, such as multiple-choice questions and fill-in-the-blank questions, can be marked. Check the whole set of papers again after you finish it to improve the accuracy.

So the steps to do the problem are: easy-medium difficulty-difficult problem.

2) What should I do if I encounter a problem? Don't worry yet. First solve the easy and difficult problems step by step, and then look at the difficult problems. If you think about them a little, you can get a few points, but of course you can't get full marks. You do your best. Generally speaking, questions 1 and 2 are relatively simple, while the following questions 3 and 4 are more difficult.

3) In fact, the most difficult thing in mathematics is to transform ideas, and the difficult problem is transformation. You may not know how to transform it. This is the difficulty. If you do it, it will be easy. When doing difficult problems at ordinary times, think more about how to simplify the complex and think about the problem in a different way. You should use your hands and brains more, write down or draw what you think, and then ponder what you didn't expect.

4) When encountering a problem, if you can't feel it with both eyes, don't ask the teacher. This is terrible. This is a problem. You should prepare at least 1-2 days and see if you can work it out. If you still can't figure out the answer within 2 days, ask the teacher. If the teacher orders a little, you will suddenly realize. If you have a problem, ask the teacher. The teacher may talk for a long time, but you may not understand. You don't understand why. Next time I meet the same type, it will be the same.
