An online tutor provides academic support to students using distance-learning formats, such as video calls, instant messaging, and screen sharing. As an online tutor, you can have one-on-one tutoring sessions with a single student, or you can host group tutoring sessions for several students who are studying the same subject. Your duties are to prepare a lesson plan for each session and teach concepts and study habits to students who are struggling or simply want to reinforce their skills in a subject.
