It is unrealistic to want to finish high school mathematics in the summer vacation. I don't know where you are from. Like the People's Education Edition, you have to learn compulsory courses 1-5 and elective courses. Do you think it's possible? Besides, high school mathematics is very abstract, which requires students' logical thinking ability and strong spatial imagination, as well as your ability to analyze and solve problems. You have to reach a certain level to calculate. So don't rush for success. I suggest that you attend classes and study hard when you go to school, and digest and consolidate new knowledge in time. I am a high school math teacher.

I am a high school math teacher. If you don't do well in math, it's totally unnecessary. Just study hard at school. Unless you do well in math and are interested in math, you can look at it and even learn more about it. That's another matter. Don't give yourself too many tasks. Your idea is very good. You can first look through the textbooks of grade one in senior high school to prepare for the connection of mathematics knowledge in junior high school and senior high school. Learning focuses on the classroom, not outside the classroom. Like the postgraduate entrance examination, college students have certain self-study ability, and high school students also need teachers. Self-study ability is very limited. Need a teacher to lead the study.
