On the question of mathematics, I personally talk about the method of making test papers!
1. I have the test paper, and I feel confident when browsing.
2. From beginning to end, do it calmly, don't panic when encountering problems, don't be happy when encountering simple topics, don't jump, and be dull first.
Don't be careless when you encounter simple problems. Many times simple questions are easy to be sloppy, so you should be very careful and treat all the questions on the test paper equally, no matter how difficult or simple.
4. For difficult problems, if you really have no clue after thinking for 3-5 minutes, you need to put it down and do the following things. Leave me alone, remember.
Remember to check back, including all the questions that need to be checked. This test is learned. You can only check those questions that you thought were simple at first. This kind of examination includes calculus and so on. Even you need to check your draft (some exams require you to draw a draft so that you can check it); Difficult projects have to be checked many times.
Finally, the problem needs to be checked before it is done. Don't make those problems too big. It is easy for you to make mistakes in the last inspection.
If you don't know how to do a difficult topic, break it down into something you think is simple. If it really doesn't work, don't do it.
You must get the points you should get, and you must fight for the points you can't get!
Personal opinion!
