I don't know what level you are. In English, you can try to explain the teaching materials (with lectures and exercises), integrate the plan synchronously, and practice and test synchronously. Mathematics can try "face-to-face teaching" and "three-year simulation of five-year senior high school entrance examination" Physics is similar to mathematics.

In the eighth grade, you can read more Chinese classics. Students of politics and history must pay attention to lectures in class. Science students must do more questions, do more and ask more questions. If you have time, you must preview the ninth grade knowledge in advance, especially the ancient poems!

That's about it. I'm in grade nine now, hehe! Well, finally, I wish you progress in your study!
