I think you should do the following:
1) What's the biggest obstacle that prevents you from learning math now?
2) Did you persist in studying? Or just three days of enthusiasm?
Give yourself a satisfactory answer before you can really learn.
In fact, mathematics in the senior high school entrance examination is not difficult, and it is basically a basic problem. Most people can play for a long time without making mistakes.
Judging from your present situation, I think you should listen to the class well. If you can't keep up, ask the teacher after class and ask him to tell you again until you fully understand. Don't be embarrassed. If you want to learn, you must pull your face down! !
Then, you should do more basic questions. To tell the truth, the exams taught in different places are different, so I can't give you good guidance. You can ask the teacher about this! ! You just need to do the basic problems now, don't think too much, and don't be ashamed of admiring others' math.
Do more basic questions, read your outline and pay more attention to the key points!
You can look at the questions in the senior high school entrance examination when you have time. Don't be afraid that you can't do it. You can always use these methods in high school and college, because the test paper is dead, and there are always those types.
Work hard! !
