Shortly before the start of each block, we offer change-of-enrolment days. During these days, you can register for courses with available places. For block 4, the change-of-enrolment days will be on 6 and 7 April (until 23:59). Unfortunately, we will not be able to process any requests received after the deadline.
Many courses only have a limited number of places available. It may well be that the course is already fully booked when you try to register.
