It depends on your educational background. If you have studied in a junior college, it will be much easier for you to graduate from a junior college. If you only study in high school, the college entrance examination will be much more difficult, because the college entrance examination is the starting point of the college, which involves many advanced mathematics knowledge that high school has not learned, such as calculus, probability theory, linear algebra and so on. But the depth and difficulty of the topic is not very deep compared with advanced mathematics. Mathematics in the college entrance examination is a selective examination, with easy accounting for only 30% and difficult accounting for 40%.
