1. Speak Chinese first. Those who like reading and those who want to learn Chinese have only one class type. Five-star Chinese is difficult to read, including reading, writing, basics and ancient prose, with rich content. There are three difficulties in learning Chinese, only reading and writing. 2. Let's talk about mathematics again. There are classes A and A+ who are willing to study mathematics, and classes A+ and A++ who hope to learn mathematics. The contents of A and A+ courses on the fast reading APP are the same as those in the book workbook, and there is no difference. A+ five stars in difficulty. The previous content is the same as other sisters in Little Red Book. Although A and A+ textbooks are the same as workbooks, the teacher said that there will be additional expansion questions after the last online class, but many of the introductions of APP are what I have learned before. What about the math A++ that I hope to learn? There is no specific content attached to the title of each course, and the content of A+ and A++ is slightly different.
