I saw these two teaching assistants in Jianghan Bookstore the other day, and I thought they were all good. I took two books and compared them one by one. I think the exam at 3: 1 will be better. It includes "error-prone topic analysis" and "senior high school entrance examination link" The question is good and the analysis is thorough. I am also a frequent visitor to the bookstore. In my opinion, generally good books and papers are not bad, so I chose them. However, for subjects like mathematics, I still recommend the double-speed learning method, hoping to give you some help!
