Faced with this situation, the most important thing for you is to adjust your mood, go all out in your study, pay attention to the process of doing things, and try to treat the results lightly.
Everyone has his own strengths and weaknesses, such as math study. Some people are really not good at it. Don't demand how high you must reach, but this is no reason to give up your efforts, so you try your best in the process. As long as you do this, you have a clear conscience.
First, try to master the learning methods that suit you, don't hate learning, and don't make excuses for not learning;
Second, chat with relatives and classmates more to relieve their pressure;
Third, plan your own time, and study takes up the most energy, but don't give up physical exercise, your other hobbies, but you can only spend 1 to 10 at most every day.
As long as you can do the above three points, I believe your situation will be improved.
