As I started tutoring being very passionate about it while I was myself at university, I always aimed at methodologies that the students can learn in depth, relating topics to every day environment through examples and analysis, rather than mugging up and capsule preparations for exams.
I believe each student have a unique style of learning and understanding concepts, thus I always recommend to have a first session to understand his/her levels and basics about the subject so far. Once discussed about the topic, the session required for the student, classes can be scheduled in zoom/Skype /g-meet/teams or others according to convenience. Regular assessments of each topic covered will be done , also depending on the students level as well as school/college assessment preparation. The students can approach for doubt clearances through WhatsApp/call as well as extra sessions can be arranged upon prior request.
