Besides learning idioms, words and numbers, are you a science student?
That depends on your major. If you are a science and engineering major, you must study mathematics (college mathematics includes: advanced mathematics, linear algebra, complex variable function, probability theory), English and physics. Each major has different pertinence, so the focus of learning these three disciplines is also different. If you are a literature major, you should learn college Chinese and simple advanced mathematics in English. Biology and chemistry depend on your major. If you study medicine, you have to study both. Basically, other majors have specialized courses, which will also involve the courses you mentioned.
