My children's primary school has been using talent classes, which is basically enough. His math performance has always been in the forefront of his class or grade, but the topic of talent class after junior high school is relatively simple, and now he uses a book called << Qidong Middle School Exercise Book >> Exercise Book, and his performance is still very good. If you are also using the People's Education Edition math textbook, you might as well try it (the disadvantage is that there is no reference answer).

The above questions are given from a broader perspective. Many inferences are basic questions and slightly complicated Olympic math questions. If you can think independently and complete the above questions according to the textbook, then the seventh grade math scores will be excellent wherever anyone teaches the textbook.
