Which is better, colorful class or coach?
I think both will do. I began to use the complete solution of textbooks in primary school and the all-pass from the fifth grade of primary school. But in junior high school, I used it less, because I felt that everything I said after junior high school was not very good. I always use a complete set of teaching materials, and our teachers often buy a complete set of teaching materials to give lectures. If you want to improve your grades, I suggest you use nudge, which is a book with many methods. It is better to use it in the middle of the book. You can use textbooks to help. Textbooks are vivid books with cartoons, and they can also help you memorize knowledge quickly. But I suggest you use click and click.
