We should find questions similar to Tian Li's Thirty-eight Episodes, and then sum up the rules of the questions.

1, multiple-choice questions, first choose simple questions that require complex calculation, you can keep them or forget them, and you can get the answer through relatively simple operations.

2. Fill in the blanks is like a calculation problem without process. It's complicated. Generally speaking, it is a simple problem, two common problems and a difficult problem. And there are often traps in the fill-in-the-blank questions that will make you make mistakes because of carelessness. Be careful.

3, big questions, such questions are often fixed questions, from trigonometric functions, functions, analytic geometry, solid geometry, probability statistics, derivatives, series, series is most likely the last big question, it can be combined with functional derivatives, so it is the most difficult to master. There are several problems to be considered, such as solid geometry, trigonometric function, and probability. You should pay attention to all three kinds of problems. When analyzing geometry and derivatives, we should pay attention to their first and second questions. Even if we can't, we should write more formulas and maybe get some points.

My experience is so much. The key is to master the skills of doing problems and doing them. Work hard.
