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. After referring to Tang Jiafeng's 20 17 (full review of postgraduate mathematics), the 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 (math relay question for postgraduate entrance examination 1800) is very good, combing the thinking and skills of answering questions and doing some simulation questions appropriately.
