Because first of all, there are some basic knowledge points in daily practice in junior high school, and there will be a more difficult additional question. Personally, I think the above concepts are too complicated and have a little foundation. It is better and more comprehensive to do the "May 3rd" or "General Review Edition" of the senior high school entrance examination. This can be done after the new class in grade three is finished. Basically, the above questions will be completed seriously, and there will be no omissions in the knowledge points of the senior high school entrance examination. In addition, there is a book called cuddle, which focuses on it and is also very good. Personally, it is better than the overall solution.
