I think that the benefits of online learning include choosing any educational institution in any country in the world, saving time on commuting and getting back to online lessons anytime you want if they are recorded. Also, you can adjust the speed of video lessons or read a transcript. You can choose what time you prefer to study or take a break whenever you want. There are also some disadvantages, for instance you can't ask a teacher any questions or talk to them personally. Sometimes there can be technical issues with the internet connection or a computer. Also, you should be highly motivated and self-disciplined to study regularly, not to miss lessons and do homework on time.
