Don't worry if you are not good at math. Our economic mathematics is a little simpler than advanced mathematics, and the final exam is generally easier. As long as you carefully digest what the teacher said at ordinary times, it will be OK. I tell you as a senior, don't worry, I mainly study calculus, linear algebra and probability theory. It can be seen that you are a newly graduated high school student, and you don't need to worry about math at all. After graduation, you will eat, drink and be merry. I am a graduate student majoring in finance.
