I suggest you make up some basic concepts or current things and make up the basic theoretical knowledge. But don't spend all your time on math. You can spend your time studying Chinese in math. If you understand the analogy, you can collect error workbooks and write down the topics that often make mistakes in the book. Some topics have similar principles. Remember not to delve into topics that are too difficult or unfamiliar. Remember to study efficiently, don't waste precious time on some topics, ask if you don't understand, don't be shy or embarrassed. Sometimes a classmate's word is better than everything.

It is also very important to remember to have a good rest, combine work and rest, and don't always stay up late. Inefficient learning methods are just chronic poison, which will backfire. Just choose a question before going to bed, think about the deductive process in your mind or remember some important theorem definitions; Or think back to what you learned today.

Don't care too much about your current grades. What you should care about is that everything you will do must be right, and you can only maximize the scores covered by some basic knowledge. As long as you show your true level in the only college entrance examination, you will have a clear conscience if you work hard.

Finally, I wish you first, to be admitted to your ideal school.

Choosing a major is also very important. You must choose what you like, don't force it. Some opportunities pass without regret.
