All-in-one class and all-in-one learning practice test are beneficial to all-in-one class. The practice of all-round learning is more difficult, and it is more suitable for top students with solid foundation or coping with competitions; All-A class is very simple, the content is more suitable for the difficulty of the exam, and students can understand and keep up with the content in the textbook. Compared with the two, most children have a weak foundation, so by comparison, all-in-one class is better. All-round learning practice test is more suitable for top students, which can enrich the learning content of top students and can be used as another practice for top students.
