1. Sort out the wrong questions. Sorting out the wrong questions can make you see your weaknesses clearly, and also allow you to spy out the ideas of the questioner. Pay attention to tidy up and do it by yourself. I put this in the first place because I think it is the most important. Must be good at summing up, such as the popular zoom problem now. I summed up several kinds of questions (these questions are usually the finale, which takes time and it is very important to master the strategy). The first step is to do more and see as many problems as possible. The second part is the method of summarizing the problem. I found that the most commonly used method is the ratio method, so you can try the ratio method first when you see this kind of problem. The third step is what to do if the ratio method doesn't work. It turns out that you need to see more problems item by item (the more types you know, the more likely you are to see similar problems). I remember that the last question in Sichuan in 2007 was a typical example of scaling, and I knew how to do it at a glance (I am from Jiangsu, not from Sichuan).
2. Do more questions, which is the second most important thing after sorting out the wrong questions. Only by doing more questions and standing high can you see far. Buy a set of simulated test papers in the experimental area of curriculum reform. There is a good tea middle school in Jiangsu, because they spare 40 minutes every noon to make a set of 4+2+ 1, choose 2 and fill in the blanks with 4 questions. If you can persist for a period of time, you can develop a fixed problem.
Stick to the last minute and don't relax. At that time, I didn't do very well in the first two or three modules of the college entrance examination, and I was scared at that time, but I persisted and did well in the college entrance examination. I fought side by side with other students, and I am very motivated to think that so many people are working with you.
As for the questions you don't understand, I can only tell you that your foundation is not solid enough and your association ability is not enough, so you can only supplement it with experience. Be sure to do more questions first and think about the answers (time is not long, there is no need to deduct a question). It is king to look at more problems and summarize more. The reason why the tactics of asking questions about the sea are enduring is that it is used by a large number of students (except a few awesome people who can do well in the exam without doing the questions). Anyway, I am one. Remember: you must sum up, do more questions and sum up often. Anyone who wants to learn well and has a normal IQ can achieve satisfactory results.
Finally, I wish you success!
