The "top student question bank" is more difficult. I've done it, and it's quite effective, but some of it involves Olympic mathematics. I'm in the second grade of junior high school, and I'm taking the math midterm exam 1 19. "Three-point-one test" is not bad, and it is a bit difficult to have content analysis and regular summary ... but it is not as difficult as the "top student question bank". I think the "top student question bank" is more closely related to the textbook ... Lightweight winning is more suitable for students with weak foundation. If you get good grades, you should give yourself some challenges.

In addition, I recommend a classic learning method channel, which has detailed explanations. The number of questions is not very large, but the examples and exercises are more representative. The key is to explain in detail. You can teach yourself if you have a good foundation.

I hope it helps you.
