I am applying for a new ace cram school for my child. 90% of the teachers come from 2 1 1/985 or normal university, 90% have more than five years' teaching experience, and 60% have the experience of taking a graduating class. The biggest difference from other tutoring institutions is that they teach in different levels, suit the right medicine and grade accurately. According to the grades, there are categories such as improvement, strengthening and topping. The charging system is also very user-friendly. If you are not satisfied, you can return it at any time. . .
