Exam Difference between face-to-face and video instruction?

Face-to-face teaching: it is the professor in front of the students to explain the knowledge points. This teaching method is more flexible, according to the student's learning ability to adjust the teaching method, students can also ask the teacher questions while studying. And the teacher will provide students with extra help and materials after class. The downside is that if you can't keep up with the class, you won't have to repeat it, and the speed of the class will be relatively fast, so you'll have to accept a lot more than that, which isn't very good.

Video teaching for well-known professors to realize the video recording of lectures, and then the students arrange their own time to watch the review. This kind of teaching method can be repeated to watch the learning content, can arrange their own time, review the efficiency will be higher. And the videos are recorded by famous teaching teachers, which has high authority. The disadvantage is that there is no opportunity to communicate with the teacher, and there is no place to ask if you don't understand. If the self-consciousness is not strong, the effect will not be very good.
