To cancel a session, just log in to your Tutorful account and go to your "Lessons" tab on the bar at the top. You will then see a list of your upcoming lessons. Select "view lesson" next to the session you need to cancel. You'll be taken through to a page with the lesson details, where you'll see the option to "cancel lesson".
If you have weekly sessions, you can either cancel just one session (if you know you'll be away on holiday, for example) or all of the sessions after a certain point (if you know that your sessions will end from that date).
If you just want to cancel just one lesson, leave the box asking if you would like to cancel this and future lessons unticked. If you would like to cancel all lessons after this one also, then tick the box.
Information regarding our cancellation policy can be found here.
