The counting principle (permutation and combination) is generally a small question (or multiple-choice question, or fill-in-the-blank question) to increase probability, and so is the sequence. Some year series have no big problems. Definite integral is usually tested in a small question, that is, 1-2 small questions. However, in the final finale, you may need to use definite integral ~ 5 points for minor questions and 12- 13 points for major questions.

By the way, math problem:

There are 8 multiple-choice questions, each with 5 points, 7 fill-in-the-blank questions, 5 of which must be done, and then 3 choose 2, (take 4, what inequality, optimization method, parametric equation polar coordinate equation, and one can't remember) with 5 points each. It involves some trivial problems such as set, proposition, conic curve, sequence, permutation and combination, integral and so on.

Six big questions, the first three are 12 points, generally trigonometric functions, probability statistics and solid geometry.

The previous questions are relatively simple, and at most the last fill-in-the-blank question is empty, which is a little more difficult than the last question of multiple-choice questions. The last three questions are questions that widen the gap, each with 13 points, application questions (derivatives or series or trigonometric functions), analytic geometry, derivatives and inequalities. It is difficult for anyone to do all these three things. As long as they can do what they can, it is not difficult to score a half point step by step. . .

In addition: if you don't learn definite integral well, it will be very painful for your child to learn advanced mathematics in freshman year. So, make up for it while there is still one semester.
