I want to join a Masterclass but it says 'Join Waiting List'. What does this mean?

If it says ‘Join Waiting List’, it is either because that Masterclass is fully booked, or because two people from your school have already booked onto it. If you sign up to the event waiting list by clicking the box on the form, everyone on the waiting list will receive an email if a space becomes available. You will then be able to log in and book any remaining places on a first-come, first-served basis.
