②. Math 1: It is the most difficult exam with a wide range and great difficulty. Almost all chapters of the first and second volumes of mathematics in Tongji High School have to be tested. Number three: It is the same as the number one exam, but the topic is relatively simple, indicating that there are few steps to solve the problem. Second: the scope of the exam is small, but the difficulty is the same as the first. The first volume of Tongji advanced mathematics is tested, and the second volume only tests "calculus of multivariate functions" and "double integrals". The number two has one characteristic. Although the scope of the examination is small, it is particularly detailed. Many knowledge points involved in the first volume of Tongji can hardly be tested, but the number two is tested almost every year, such as the application of definite integral in physics and geometry.
Generally speaking, there is more than 90% chance that you will get one in the exam.
