This is really up to you, but we have a few suggestions.
First, talk to the client in advance of the lesson.
We recommend you call the client within 1 hour of receiving the notification about the lesson. Be polite and do your best to deeply understand their needs, and why they want to learn that skill or subject.
If applicable, obtain a copy of the relevant textbooks, course syllabus, etc., and work with the client to draw up a personalized lesson plan before your first lesson.
Second, try to get repeat business!
The hardest tutoring session to prepare for is usually the first one with a new client. Tutors who offer superb service to clients are more likely to be hired again.
For follow-up sessions, you will know exactly what's expected and preparation will be a lot easier. Learn more about getting repeat business.
