Well, it depends. First of all, according to your major, if your major is complicated, you may have homework, and then you may meet the teacher. If the teacher is in charge, he may give you homework. Then according to your study, you need to do your homework if you are not solid enough. And if you want to learn a certain degree, but you can't reach that level through online classes, you need to do it yourself or according to the teacher's requirements. College students' online classes are not related to their homework. Every major needs to study hard and everyone can do homework. Below, I searched some related learning contents, most of which are professional. (The picture is from the Internet and is for reference only. )
