Advanced mathematics is a difficult and thorny subject in university. Taking classes is of little use to learning advanced mathematics, so it is still very useful to make a surprise attack before the exam.

Higher mathematics refers to a more complicated part of mathematical objects and methods compared with elementary mathematics and secondary mathematics. Algebra, geometry and simple set theory in middle schools are called secondary mathematics, which is regarded as the transition between elementary mathematics in primary and secondary schools and advanced mathematics in universities.
