The most important thing in science is not to do more problems, but to master the method of solving problems. This is the key point. Because time is running out, what you need to do now is to take out the papers of the previous large-scale exams (such as mock exams and monthly exams), see which topic you made the most mistakes, that is, your weakest link, and then conquer it. You should have classmates with better grades than you. At this time, you should make good use of these resources. Don't be afraid of losing face when you don't understand. Ask them quickly. There is also "returning to the textbook". Although it is annoying, it is sometimes undeniably useful, especially for the basic theories of formulas and laws, which is helpful for you to do proof questions and inference questions (I don't know if you have such questions now). During this period, don't talk too much about sea tactics, but should analyze weaknesses and make up for shortcomings.

And according to your own actual situation, there must be a lot of questions that you won't do (I'm not hitting you, I'm telling the truth).

If you do more questions now, it will only hurt your self-confidence. In your case, I think your choice to overcome the fill-in-the-blank problem is the most important. I asked many classmates or teachers.

Come on, I wish you success in the college entrance examination.
