You are typically expected to travel to your client's home for lessons. When you sign up you'll be asked to add the "area you're willing to travel" on a map. If your client lives within this area you're expected to travel to them (where possible)
Some tutors do occasional lessons via Skype when required. If you would like to make this arrangement, please message the client with your request and have them confirm they're happy with that format.
If you are unable to travel to a clients home for any reason, please make sure this is very clear between you and the client before a booking is made!
