Learning psychology involves some mathematical concepts, but it is not the main aspect. Advanced mathematics is a basic and compulsory course for psychology undergraduates. Generally teach calculus. The last school year lasted for two semesters, mainly because psychology has both the nature of arts and sciences and the side of science.

Psychological statistics, psychometrics and experimental psychology all require students to have certain mathematical ability. If you want to learn some deeper directions, such as IRT theory and structural equation model commonly used in psychological and educational statistics, you should not only learn calculus, linear algebra and probability theory.

If the interest lies not in psychological statistics and measurement, but in the psychological direction of literature such as psychological consultation and social psychology, then advanced mathematics is limited to that academic year. If you pass the exam and get credit, you don't have to study math.

By the way, if you want to take the postgraduate entrance examination, psychostatistics, measurement and experiment are compulsory, and you need to have a certain ability to use mathematical logic thinking.
