You can buy the primary and junior high school graduation version of "Five-Year High School Entrance Examination Three-year Simulation", which is more detailed.

I'll do this question, my science grades have always been good, especially junior high school chemistry, mathematics have been taken in the country, I am also a junior in junior high school, I have learned a lot, thank you You better not use any reference books or anything like that, like this.

Keeping one's emotions in a stable and positive state is a common ability of champions. Positive emotions can help you stay in a good state of study, and you need to learn some ways to regulate your emotions or vent your emotions.
