First of all, we should understand the knowledge points of high numbers, instead of starting to brush questions; I believe that I have the ability to make a name for myself in the final, and I should also review linear algebra seriously. So textbooks are a good recommendation. Secondly, look at the previous topics, sort out ideas and master the test sites. So the real question can be used as a reference. Finally, I insist on having this information. I think the "Guidance Guide for National College Students' Mathematics Competition" is good.

First of all, remember, of course, not by rote, but by understanding! If you really don't understand it, you can only recite it, especially concepts, theorems and formulas. Pay special attention to the conditions for applying formulas, conclusions and theorems to solve problems.

The method of comprehensible memory is to understand its context, but it is not a process of investigating its history, but a process of citing examples, counterexamples, derivation, popularization and extension in teaching materials and classroom teaching to form definitions, theorems and conclusions.

Teaching material examples and after-school exercises should be done independently. At least after reading the answers, you should be able to do it the next time you see similar questions with changed data and symbols! Pay attention to the connection between exercises and examples, concepts and theorem conclusions! Be able to solve new problems with the help of practical solutions and related conclusions! They are the "prototypes" of various exam questions that are often mentioned.
