The knowledge you have learned is scattered, and there is no system, no system and no framework. The word "earn some money" means there is no knowledge system. In fact, your situation is quite common. Senior one and senior two mainly study chapters, learn what to use, and take the exam with a slight change of the topic, so it is relatively simple. Senior three pays attention to chapter synthesis and subject synthesis, and there is great pressure to learn without understanding knowledge. My advice to you is: first, keep up with the teacher's rhythm, familiarize yourself with the textbook first, and make up what you can't do.

Second, summarize the knowledge used by teachers in class and form a framework. For example, draw a tree diagram, a frame diagram.

Third, summarize the problems that the teacher said and the methods to solve them.

Don't wait for the teacher to give you a summary. You are the teacher's, only your own summary is yours.

Proper practice is very effective for us ordinary people to put forward sea tactics.

I hope I can help you, please adopt it if you are satisfied, and welcome to ask questions if you have any questions.
