Before inserting books, you must first determine the school level you want to take. If the score is not high, it is recommended to focus on English and politics. For the other two professional courses, you can usually read books and review materials given to you by the teacher. Because the topics of the professional courses are not open, it is not cost-effective to put your chips here, but you must review, at least the basic topics must be done. If you want to enter a university like Shenzhen, mathematics can't be ignored.

Why are the candidates increasing, but the scores are basically the same? In fact, it increases the difficulty of the topic. This is to raise the score line in disguise. 10 year is more difficult than previous years, while 1 10 year is more than one level. Therefore, it is recommended that the landlord review all 5 subjects. Focus on English and math. Among them, English and CET-4 are two test sites, which are not comparable. Don't think that there is no pressure to insert English after CET-6.

Aiming at the problem of the height of the landlord:

The height of the insert is not the same as that of the college entrance examination mathematics. The high-number questions in the inserted version are basically stereotyped (it is recommended that the landlord buy a set of real questions from previous years), and what kinds of questions are there every year? And the score is low (6 points). The last two questions are 10 and 12 respectively. Monotonicity of one of the functions (studied in high school, but with the definition of inflection point). Another problem is to prove that the function must be less than a certain number and greater than a certain number by Rolle theorem and mean value theorem, to prove that a proposition or equation has multiple solutions by the definition of derivative, and to find the area by indefinite integral. 90% are all these three questions.

For the theorem, it is actually similar to what you think. There are a few exceptions, such as the definition of derivative, Rolle theorem, the area of definite integral or the volume of rotating body, the general solution of differential equation, etc. You must understand the derivation process (not by rote, the theorem of the test paper is unverifiable, but the question is not directly asked, so you can't turn around for a while). As for the proof process of theorems such as integrals in undergraduate mathematics, I dare say that few teachers can understand it. If you understand, you will become a god. MV？ Can you understand this process? But you will do it.
