Xueersi Primary School has a good performance in Olympic Mathematics, so you can directly register for the Cup. There are quite a few students.

New trump card

First, divide classes, one class is good, and the other class is better;

Second, the number of students is small, about 10, and the class atmosphere is really good. Don't leave after class, you still have to ask the teacher questions.

Third, you can charge monthly. If the family condition is not good, just pay it every month.
