As a science student, I can only give you advice on science.

Mathematics-the complete interpretation of the textbook is better than the analysis of the textbook, and no explanation is needed. I still suggest that the exercise books be carefully distributed by the teachers, and there is no need to buy more. Believe me, we must consolidate the teacher's arrangement, such as basic training and so on.

Chinese-focus on practicing ancient prose, buy a copy of Xinghuo's ancient prose analysis is very good, and Longmen's ancient prose topic is also good, so you don't have to follow the class.

English-I have been using Wang Houxiong to study this case, which is very good. I wonder if you have subscribed to a high-quality English weekly.

Chemistry-It is recommended to do exercises of 3D design, and explain them in detail. If you follow the class, there will be no mistakes and it will be very detailed.

Physics-A Case Study of Wang Houxiong, a good book with explanations and questions. It is not recommended to purchase workbooks separately.

Biology-it is strongly recommended that the guidance practice should be green and white, with detailed explanations and moderate topics, which can achieve high efficiency.

Geography, politics and history, we suggest that Wang Houxiong study cases, which are basically used by liberal arts in our school.

I hope you are satisfied with my answer.
