You'd better find out which subjects the math department chooses first. Do you take the math exam? If you take the math exam, you will make a lot of money. If you are not a math major, our math department has considerable advantages (as long as your English is not bad). You have to pay attention to the specialized courses yourself. In mathematics, we must learn mathematical analysis and advanced algebra well. It will be fun to look at advanced mathematics and linear algebra later. So is the probability. As for politics, I'll review it when the outline of the senior three exam comes out. Do a good job in math, English words and reading before the third year of high school. Mathematics firmly grasps the textbook, which is king! Choose your favorite English word book in English (everyone has different habits, so it is not easy to recommend it, for fear of misleading you). Reading strongly recommends English learning and Crazy English (Reading Edition).

Specialized courses can't help you.
