Answer: The contents of online courses and face-to-face courses are basically the same, but the learning effect varies from person to person.

Some students like online courses, because online courses don't need to come to the scene to attend classes, so they can attend classes directly at home, which is more convenient and flexible. They can choose their own class time and listen repeatedly during the validity period.

Some students like face-to-face teaching, because face-to-face teaching courses are more direct, and they can communicate directly with teachers on the spot, and any intractable diseases can be solved immediately, which makes them more learning atmosphere and motivation.
