Specializing in pedagogy, psychology, educational psychology, educational history and so on, I read a lot of books, mainly memorizing, but didn't take any math tests. There are pure mathematics and pedagogy directions in learning and mastering. The direction of pure mathematics such as applied mathematics, basic mathematics, probability theory and mathematical statistics is the high generation with high scores, and the direction of education is called curriculum and teaching theory, which is similar to master's degree and consistent with liberal arts education. If you have a good memory, poor math and strong understanding of liberal arts, I suggest you take a master's degree or a course to teach theory. I don't like those, but I like higher grades. Pure mathematics, of course.
