My hourly rates are determined by the level of the student and whether tuition is one to one or in a group.
Lessons are paid for half a term at a time by online bank transfer into my bank account. In order to secure the place lessons are paid for one week before the half-term begins.
If lessons are unavoidably missed I can normally rearrange the lesson either in the school holidays or when I have another cancellation. This is at my discretion and there has to be a sensible reason for missing a lesson.
I also tutor on Skype with my own online classrom so if the weather is particularly bad or transport is a problem lessons can be held in your own home.
