Although some knowledge points have the same names, the depth of investigation is different. Engineering majors must choose 1 or 2 because of their high requirements for mathematics, and economics and management majors must choose 3 or 4 because of their relatively low requirements for mathematics, but the specific subjects to be tested are stipulated by the admissions unit.
You'd better buy this outline. Obviously, it's usually not difficult. It's a public course, and it won't be difficult, but it will be much more difficult when it comes to specialized courses, such as mathematics department. . .
