Multiple-choice questions are easy to grasp the concept, and the reduction in the number of big questions also means overall improvement, which requires candidates to truly understand knowledge.
There are fewer and fewer questions and skills that can be applied without understanding the connotation. There is no market for "spike solution". Read more textbooks to understand the ins and outs of various methods of doing problems.
2. Pay attention to the examination of computing power. The amount of calculation is increasing, and the knowledge points should not only be learned, but also be fast and accurate. Therefore, it is absolutely necessary to practice after class. If you don't understand it, you should strengthen the training of accuracy and speed of calculation in unit time.
pay attention to
First, the proof of the limit of sequence.
The proof of the limit of sequence is the focus of number one and number two, especially the number two has been tested very frequently in recent years, and several big proof questions have been tested. The big problem generally involves the proof of the limit of sequence, and the method used is monotone bounded discrimination.
Second, the relevant proof of the differential mean value theorem.
The proof of differential mean value theorem has always been a difficult point in postgraduate entrance examination, and its examination is characterized by strong comprehensiveness and wide knowledge.
