2.”Youteaching”
Another variant of online teaching is what I got to call “youteaching”. This is quite easy: open yourself a channel on youtube, practice your lessons in front of a camera and then record it. Then put some publicity on your videos. At first it might not be a lot of money, but it will increase with time. It might also work as publicity for you as a home tutor. And, in the end it’s something you can do one time only while you’re on vacation and just let people play it and replay it as much as they need.
