If the foundation is really poor, look at the basic knowledge first and memorize everything you need to remember. In fact, there are many things in mathematics that need to be remembered, and people always ignore this.
Then the key is to do the problem, find your own shortcomings, and then make up for it.
Under normal circumstances, 80% of the college entrance examination is a basic question, so we should grasp the foundation and don't waste too much time on difficult problems.
Mathematics sometimes feels very flexible, but there are still rules and formulas to follow. Pay more attention to summing up yourself. Don't make the same mistake again and again.
When the time is tight in the later period, you can take this way: look at the question, think about the idea, and look at the answer within 3 minutes. Just like your own way, go on to the next question; If they are different, we should first distinguish right from wrong, and then compare the differences between the two solutions when they are right. If you can't find an idea within 3 minutes, just look at the answer directly and think about why the answer is like this and which step you didn't expect.
The key is to do more questions, but not too much. After all, time and energy are limited. When making up mathematics, don't miss other courses to ensure the dominant position of dominant disciplines.
Don't be too anxious psychologically, although there is not much time, it is still enough. Pay attention to strategically and despise tactically. It's important to keep a good mood. Don't be impatient, there is still time, take it step by step, and there will be good results!
I wish you success and get your satisfactory score!
