Ensure the correct rate of multiple choice questions. You can take out several sets of simulated questions or real questions you have done and classify all the multiple-choice questions. You will find that there are only a few types of questions, and you will be examined in those aspects. Do some questions for the test center purposefully. Learn to eliminate and analyze problems. If there are still big questions, practice them in different categories. Try your best to achieve what you can.
Secondly, in the rest of the time, take time to look through math books, maybe there will be unexpected gains. There will be some unexpected questions in the college entrance examination. Maybe the concept definition you read will be of great help to you.
In addition, learning mathematics must stand on a high level and grasp it macroscopically. Don't do it again, you will find that this is the case. You must be serious when you do it. You must go in and force yourself to jump out at any time.
The score of each exam is a standard to measure you, or just a relative standard compared with other students. Don't care too much about these. You can analyze the total score of your test paper and classify this score to see if it is an error, a conceptual definition or a calculation error. Spend a class to do these tasks, and maybe you will understand after taking out three or four papers.
Finally, relax. That's how my sister came. Don't be afraid, everything is unknown before the college entrance examination. If you don't believe in yourself, no one will believe you. Whether you are afraid or not, he is there. Why don't you try again? If you need any help, you can ask me. I sincerely congratulate you on getting good grades in the exam.
