When you graduate from high school, it is basically the peak of a student's studies. If you take the CET-4 in this state, you are likely to pass.

If it is not a special major, generally speaking, high school mathematics knowledge is enough.

In addition to specialized courses, universities basically follow the knowledge of high school in basic courses, and high school students have great advantages in learning the basic knowledge of universities.

As a student, I don't think I have any say.
