For Chinese, I usually only buy a textbook or a few poems. The teacher's lecture is not as detailed as that in primary school. There is a Chinese guide in the school. "Basic training", just do some of the above examples, don't spend too much time, read more extracurricular books, it should be almost the same, recite what you should, Chinese is not difficult, reading comprehension and composition depends on your personal understanding and foundation.

In mathematics, we usually do basic training &; Qidong middle school exercise book, Qidong has difficulty level. If you can choose a topic to do or solve a problem, the teacher will print some papers, and there is a book called New Thinking. ...

We didn't do any exercises in English, so we subscribed to an English weekly and bought a book with explanations and exercises.

Physics is a few books issued by the school, printed by the teacher, and "Hours", and I bought a copy of "Complete Explanation" myself.

Other subjects are minor subjects, so you don't need to buy exercise books, just remember the knowledge points and look at some classic examples. I sometimes go online to find resources to download ... for example, some subjects mainly rely on my own hands-on experiments and brain thinking, and rote learning is useless. . Many people in the class have gone to make up lessons. I don't think it's necessary. The key teachers will bring it up in class. If you preview, you can see for yourself what problems should be solved.

PS: Personal circumstances are different. In the second year of junior high school, I learned People's Education Edition, Shanghai Science Edition (Physics) and Beijing Normal University Edition (Biology). You can ask your former classmates about the choice of teaching assistants. Thank you~
