There are reference formulas on the test paper, 80% of which are useful to guide you in solving problems.

(2) There is a ladder relationship between the small questions in solving problems, and usually the conclusions of the previous questions should be used in the later questions. If the first question is proof, the conclusion can be used in the second question even if it will not be proved. Of course, we should also consider the independence of the conclusion.

Paying attention to the bracketed part of the topic is often the key to solving the problem.

2. The choice of answer strategy

(1) easy before difficult is the principle that all subjects should follow, and math papers are more important. Generally speaking, the last two questions of multiple-choice questions, the last one of fill-in-the-blank questions and the last two questions of answering questions are difficult problems. Of course, for different students, some simple topics may also be their own problems, so the difficulty of the topics can only be decided by themselves. Generally speaking, a small problem has been thought for 1 minute, and the solution has not been established. What measures should be taken? Give up temporarily? Finish the questions you can do and answer them later.

② Multiple choice questions have their own unique solutions. The first thing to grasp is that choosing a branch is also a known condition. Using the relationship between branches may make your answer more accurate. Remember not to? Make a mountain out of a molehill

Pay attention to solving problems step by step, and write possible formulas, methods or judgments according to the known conditions of problems and the relationship between them. Although you can't answer completely, you should also write your own ideas and practices on the answer sheet. You won't get extra points if you write too much, but you may get extra points if you write too much.
