First of all, from different learning requirements:

Offline education can communicate directly with teachers in class, and it may be better to supervise students. Online education, because the teacher is not around the students in class, is taught by video, so it tests the students' consciousness. But whether offline or online, it is up to the students themselves. If you don't want to learn, even offline education, teachers can't force you to learn.

Second, in terms of study time.

During the study period, if you just have something to do, you have no time for class and offline education, and the teacher will not delay the learning progress of the whole class because of you alone, then you can only miss this class. Online education is recorded and broadcast by some institutions, so you can't catch up with the live broadcast. You can watch the recorded video for self-study at any time, and you can ask the teacher if you don't understand.

Third, from the place of study:

Online education, no matter where you take classes, you only need to have a computer or a mobile phone. Even if you are on a business trip, you can study in other places. But for offline education, we must find a place close to home, otherwise the time spent on the road will not be enough to study the content of a class at home, and sometimes it will be more troublesome if it rains and winds.
