First of all, you should take good care of the third grade courses. When you take good care of the third grade courses, you can do a mock examination paper of a subject every night. Of course, if you haven't taught it, you should let it go first. If you have taught it, you can't or still make mistakes, so you should pay attention to it. You should prepare a notebook dedicated to recording mistakes, and know why you made mistakes and that knowledge point. It is best not to understand it, do the topic, and not ask for it.
As for history and politics, it's even simpler. Take about half an hour to recite half a course every night, and repeat it every Saturday and Sunday, so that you can't forget the knowledge points.
Since you are weak in math, you should intensify your math study. For example, on Saturday and Sunday, you should set aside a morning to do math problems, buy a textbook and so on. If you don't understand, you should mark it, copy it in your notebook, and ask the teacher in class. If the students don't understand, you should ask. This is the fastest way to improve your grades.
If you are studying physics, you should pay attention to memorizing those formulas. Don't forget them in disorder. Listen carefully in class and do the homework assigned by the teacher carefully. In your spare time, make the tutorial books you bought, and do them one by one slowly. Don't bite off more than you can chew.
For Chinese, get up early in the morning, say around 6: 3, and then read the text and recite poems. Morning is the best time to remember. On Saturday night, relax yourself and buy some extra-curricular books, such as magazines like readers and Yilin. These magazines usually contain a lot of beautiful articles, which will definitely help improve your writing level.
In English, it is better to read the text carefully than to recite the English composition, so that your sense of language will be greatly enhanced and your test scores will be improved. Personally, I suggest that you write a short composition by yourself every week and hand it over to the teacher for correction. You should know that the teacher is used to ask questions and say without asking questions.
The most important thing is that health is the capital of the revolution. Students should pay attention to the combination of work and rest. It is best to play ball and run after class every afternoon. It won't waste you much time, but it will make you healthy and cheerful. And go to bed early at night, and never stay up late to talk.
and keep calm, don't worry, you can't eat hot tofu if you are in a hurry.
