Most of the former questions are from previous years, which are relatively basic and slightly difficult. Now that I'm in college, I'm qualified to share my experience with you, hehe. Don't be single-minded when you meet a particularly difficult problem. You should combine your own situation, see what level you belong to, and pay attention to the basic and intermediate questions. You should know that the college entrance examination has many basic points, even the final one.

I suggest choosing the former. That book is quite thick, study it carefully. Finally, I wish you a golden nomination.
