When I was in junior high school, I used on-demand and honor student handbook. If I get good grades, I suggest buying on demand. Some basic training questions, ability improvement questions and innovation questions behind it are very helpful to solve some difficult problems in mathematics. Generally, the last question has several short answers. The first and second questions are the simplest. As long as you put the relevant formula on it, even if it is wrong, the marking teacher will give points. It's called skill. I used to do this. Double speed is not a good exercise book, and the topic is not very difficult. If your grades are not good, which one is really a good choice, I suggest you buy one.
