Very useful. I have used blue skin 53 before and found that the effect is not very great. Eva did a lot of problems, but her grades didn't improve. My deskmate's mother asked me to change Dao Xia's "Famous School Scholar's Knife Roll", saying that with this synchronous training book, children's review is very systematic, and unit test sites, after-school exercises, missing items and parental guidance can all be solved in one book.

Tell me how children use it:

The usual habit is to get the questions and do them directly, and I don't know if the questions have anything to do with the test center. The test sites are incomplete. There are famous schools with sharp knives and test books, which are not only complete, but also need to read the test books before doing the questions to let children know their learning goals;

(2) Then start to do the problem. This problem is a famous school problem, which is point-to-point with the test center and can help children practice the test center;

(3) There is also an evaluation book to judge the degree of children's mastery of the test center. Not everyone will know where they will be;

The last analysis book is more detailed than other papers. Not only solve the problem step by step, but also very clear. I can understand it at a glance and solve the problem of our parents tutoring their children.
