First of all, general online courses will give you handouts. I suggest that you make a good handout in advance, so that you can compare your own method with the teacher's and choose the one that suits you. Then if you don't have time to do the lecture in advance, do it after class, or you will forget it soon.

Second, when you broadcast the online class live, you should concentrate as much as possible. In the process, don't think I have to take notes or anything. The teacher will send you the class notes after class. It's not too late to sort them out.

Third, listen to the arrangement of the tutor. After all, they have brought a lot of students, are experienced, and know how to arrange them, which is good for you. Then, I want to communicate with my tutor more. I think it's clear that if you communicate with him more, maybe your way of thinking will change. After you get to know him, he will also pay attention to the questions raised in your class. Ask more questions to the tutor, because in general, if the lecturer doesn't have a good grasp of the content, he still has no idea to do it.

Finally, online classes should be replayed, because our little brain can't hold so much knowledge at once, especially things like mathematics and physics, and it will be divided into more types of questions, and we will forget faster if we don't watch the replay.
