Review, I have a few suggestions. Are they targeted?
1. Synthesis and Encyclopedia: Read more extracurricular books. For example, why didn't Yuan Zong have a grave after his death? Read more history books.
If you know something about the four beautiful women and the four ugly women.
2. Mathematics: Mainly do more questions. To tell you the truth, I also think the Olympics is really difficult, but I have to have enough courage to overcome it.
3. Language: Reference 1.
4. English, probably listening, speaking, exercise books, etc.
I hope it helps you.
