First of all, you must realize that college mathematics is very rare. Compared with other subjects, you must have a clear understanding and grasp of your own ability, not to mention how well you learn mathematics in high school, and you can learn it well in college. This is a very wrong idea, because there is really no comparability between primary school mathematics and middle school mathematics, and the learning methods are different.
Moreover, I would also like to remind you that most of the problems in mathematics major are proof problems. Our basic courses include mathematical analysis, advanced algebra, topology, complex variable function, real variable function, abstract algebra, mathematical statistics, probability theory and so on. If you are interested, you can know it in advance.
