Is it difficult to take the postgraduate entrance examination in mathematics? Can you learn by self-study? I am a liberal arts candidate with a weak foundation. I want to take the postgraduate entrance examination, but the biggest difficulty is math. Answer: Math III is a little simpler than Math I and II, but most of Math III is an applied problem, which requires a comprehensive understanding of knowledge. In fact, Math II can also be tested, and both high numbers and linear algebra can be tested. If you are a liberal arts candidate, I suggest you find a major that doesn't need to take math exams. If you have to take the exam, choose three out of two, each with its own characteristics, and the number three is relatively simple. Self-study is a bit difficult. I suggest you sign up for a remedial class.
