我很担心自己能否跟上学习进度，也一直在做老师们布置的阅读任务。

I am concerned about keeping up with my studies and have been doing the required readings, as assigned by my professors.

网上学习并不比普通的课堂学习容易；它需要花更多的时间，需要学习者专一、自制，以跟上课程进度。

Online learning is not easier than regular classroom study, it requires much time, commitment and discipline to keep up with the flow of the course.
