Mathematics education in primary schools is not very difficult, because it focuses on the essence of teachers and education, and it is not entirely about learning relevant theories of mathematics, so it is not too difficult.

Normal mathematics and applied mathematics are relatively difficult. Mathematics and applied mathematics are pure mathematics majors, and it is not easy for this major to learn a lot of advanced mathematics during college. If you are very interested in mathematics, and have strong mathematical logical thinking ability and a little talent for mathematics learning, then the majors of normal mathematics and applied mathematics will be a good choice.
