First of all, teachers must elaborate that frequent interaction with students in the course of live broadcast can greatly stimulate students' enthusiasm for learning;

Secondly, the students responded enthusiastically to the class and were very enthusiastic. They actively cooperated with the teacher's small interaction in class. If you still don't understand, you can ask the teacher for advice after class.

Finally, whether you study by yourself or listen to the teacher, you must have superhuman self-control and don't mess around at will!

I hope you can have a satisfactory result in the end.
