Now maybe your basic knowledge of mathematics is not very clear. I suggest you read more textbooks, read some important knowledge points and avoid some dead ends at the same time. Then do the questions in moderation, there is really no need to engage in sea tactics. Remember to look at the topics you have done before, especially if you won't. What you can't do is a stumbling block to your success. Travel is to communicate with teachers and classmates. Finally, have confidence in yourself. If you lose, no one can help you. Finally, I wish you good results in the college entrance examination!
