The most important thing in math review for postgraduate entrance examination is to do problems. However, doing the same topic, different people get different results. A very important reason is: summary and analysis after doing the problem. In fact, whether doing exercises in textbooks or real questions over the years, we should summarize the test sites of analysis questions from macro and micro levels and summarize the problem-solving methods of questions. It is necessary to pay special attention to the unique processing methods and operation skills, and carefully consider how to dig out the key points and starting points in the solution under the condition of dry questions.

In addition, you must prepare a special exercise topic and write down your answers completely, instead of sketching them in your mind or writing them on toilet paper. In the review stage of summer vacation, it can be said that time is abundant. Don't think it is a waste of time to write down those steps. The advantage of writing down the answers is that every time you do a problem, you can clear your mind and clearly show the reasoning process according to the logic of the problem. The steps are interlocking and the middle process is complete, which is the requirement of the exam for answering questions. In addition, it is also convenient to check whether the answer is wrong.

Another important job in doing problems is to learn to classify problems. Through your own practice, you can roughly divide the topics into four categories.

The first category: If you can solve problems easily and operate smoothly after learning the knowledge in this chapter, then such problems fall into the first category. This kind of topic has really been learned and mastered by you, so we don't have to spend more time and energy on this kind of topic and mark it as "pass".

The second category: If you need to spend some time (about 15 minutes) to solve other basic questions, then such questions imply that you are not familiar with the knowledge points, starting points or key points of the exam, so you should intentionally train yourself to learn such knowledge or methods in future review.

The third category: Other problems, if they can't be solved by their own analysis and take a lot of time, but can be solved with the help of answers, fall into the third category. This kind of topic will be the goal that you must overcome when you enter the second stage of review. So, I made clear the review goal and found the focus of my next review.

Finally, if you can't finish some questions even with the help of answers, you only know why, which means that the knowledge points investigated by these questions are your blind spots at this stage. This requires you to pay more attention to the study and application of these knowledge points in future review. And this topic has become a kind of question that you should try to master in the next stage of review.

Through the above analysis, we should know what a real "problem solving" is now.

In addition, it needs to be explained that it is not advocating sea tactics, but advocating simplicity, that is, doing some typical questions repeatedly, so as to achieve multiple solutions to one question and changeable questions. Training the ability of abstract thinking, the proof of some basic theorems, the derivation of basic formulas, and some basic exercises should not be written, but only meditation. People with solid basic skills have many ways to meet problems and are not easily stumped. Therefore, students must pay more attention to thinking, practice and summary in the learning process. In this way, your study will be greatly improved.
