It's very late to prepare for the postgraduate entrance examination according to your present situation, and it takes a long time to review and prepare for the postgraduate entrance examination mathematics. But you said that you asked math to cross the line, and it was no problem to take other subjects yourself. Advanced number and linear algebra in the second test of mathematics. At this stage, I suggest you review the real questions of Math II and the knowledge points of Math II. According to the test paper structure of number two, combined with knowledge points, the review effect will be better.

I wish you success in preparing for the exam.
