Mathematics 1 and 2 all involve four knowledge points in the above picture: number theory and operation, algebra and function, geometry and measurement, mathematical analysis and statistics.

-Math 1 is less difficult than Math 2. Math 1 has less difficulty in examination questions, calculation and knowledge points. For example, the law of sine and cosine in trigonometric function is not tested in math 1, but it is one of the test sites in math 2.

Compared with Math 2, Math 1 has a higher fault tolerance rate. Explain here that the fault tolerance rate refers to how many questions are wrong and full marks are returned. The exact fault tolerance rate is anyone's guess, but the fault tolerance rate of level2 should be about 5 to 8 errors. Therefore, candidates are usually advised to take Math 2 instead of Math 1, because as long as they have a firm grasp of knowledge points, they can get higher scores in Exam 2.
