Is it really useful to simulate the three-year senior high school entrance examination for mathematics in grade three? I am optimistic that many people will buy it, but I think it is very general, but it is not bad to win the championship lightly. It depends on your own learning level. You can do more exercises if you have a good foundation. If not, you'd better read some books with strong explanatory power. Among them, the three-year simulation of the five-year senior high school entrance examination is really good, but I don't know if I am with you. It is best to choose a counseling book that suits you.
