If anyone will cancel their booking for plab 1- August/ November in London/ dubai/ other.

Hi. Do you have access to the timetable? I’ve got a booking for May in Belfast I’d like to swap out as I can’t get a visa. I’m reluctant to cancel it as yet without having a look at the timetable and checking out my options. Are all test centres globally fully booked for the entire year? Any and all help will be appreciated
