First, the lecture cycle: students can listen to twelve classes in a cycle. This can not only meet students' learning requirements, but also increase their sense of urgency.
Second, study freely. You can study selectively, that is, if students are weak in their own study, they can skip other parts directly.
Third, ensure the famous teacher. The number of first-line teachers is limited. How can we ensure students' requirements for famous teachers? Online school courses can guarantee this.
Fourth, the cost is small. Just study at home and reduce the fare and other expenses.
Fifth, time is flexible. Candidates can arrange their own study time.
