2. Mathematics: The basic content of mathematics in the college entrance examination accounts for 70%, which means that if you keep up with the majority, you should be able to get about 100. These can be done as long as you remember the concepts by classification, do the exercises required in the book and master the methods. The key is to understand the connotation and extension of the concept, and to understand a problem by yourself, so as to truly master the methods to solve a class of problems. Not much, but really understand other people's ideas and uses.
If the basic math problems are solved, and there is still time, you should be able to reach 1 10 or 120 by classifying the big questions that must be tested every year, such as conic, probability, series and solid geometry, which is very good. It is not easy to raise them higher, and the rest of the time may not be allowed.
