Unlike in the real world where you need educational certificate and license to teach, in the virtual world if you know something very well, you can tutor online and make money. However, the main thing to consider is how easy or difficult it is. Well, becoming an online tutor is more than just having knowledge, you also need to know how to effectively use internet technology, how to market your tutoring service, how to reach target audience. You can use platforms like Zoom, Google Meet, or even Livestream on social sites (preferably youtube) or eLearning websites. Likewise, you can also create and sell your courses on learning platforms or directly on social media.
