1. Mathematics review must be comprehensive. Read a book intensively for at least 3 times. The first time, you don't need to understand it very much. After a cursory reading, you can mainly review it. Read carefully for the second time, do exercises while reading, and do exercises after examples. Methods should not be limited to the methods in books (textbooks are written in order, and some of the latter methods may be used in the previous chapters. Pay special attention to this point in the second time, and summarize it in time. It is best to take notes. Read it for the third time after a while. This is the last time I read a book. It is difficult to digest line generation, high number and probability together. This is the process of your qualitative leap.
Remember that you can't get full marks in math review, just focus on the key points, which is not contradictory to the above. The above is just the basic concept that runs through. What is said here is the specific method to get the score. The high number accounts for the most every year, followed by line generation and probability, but the easy points every year are probability, followed by line generation and high number again. It seems that everyone thinks he is good at math, but it is not.
