Online learning gives us a lot of opportunities that we have never seen in school, and online learning still allows us to absorb the same amount of knowledge as when we were in school. Firstly, we can stay at home to study and it is a comfortable place for us to absorb knowledge. Online learning helps us grasp the lecture better because the teacher will speak or record the lecture through a microphone and when listening to the lecture, the sound will be very clear and easy to hear. In addition, we don't have to worry about study time because online learning is very flexible. Teachers also provide us with flexible lessons to meet our needs. The final advantage is that we can store learning materials by recording our lessons. Furthermore, teachers often record lectures and post them on the school's intranet so we can easily review the lectures at any time.
