Online learning offers us a lot of opportunities that we have never seen before in school, and it still allows us to absorb the full amount of knowledge as if we were in school. Firstly, we can stay at home to learn and it is a comfortable place for us acquire knowledge. Online learning helps us grasp the lecture better because the teacher will speak or record the lecture through the microphone and when listening to the lecture, the sound will be very clear and easy to hear. In addition, we do not have to worry about study time because online learning is flexible. Teachers also provide us with flexible lessons to meet our needs. The last advantage is that we can store study materials. Through Zoom calls, teachers often record lectures and upload them to the school's intranet, so we can easily review the lectures at anytime.
