Really, it’s up to us to set our rates. Take into consideration the time it takes to go, what they have you doing and your own personal time, but don’t go too crazy on the rates. It’s a great way to go with some extra money. I have two families I have tutored for, one for 7 years now and the other for 4.
Even they consider my rates low, but I love going there and it’s fun. When it just feels like a job taking up your free time, you will start to not enjoy it.
