It is difficult to take the postgraduate entrance examination for mathematics, so we must pay attention to the solid review of basic concepts, basic theorems and basic formulas. Refer to Tang Jiafeng's 20 17 comprehensive review of postgraduate mathematics, and the follow-up review will be much smoother. After laying a good foundation, students should pay attention to the practice of real questions and do them again and again. Teacher Tang's "relay problem of postgraduate mathematics 1800" is very good. Sort out the thinking and skills of answering questions and do some simulation questions appropriately.
