If you interrupt your studies and would like to re-register for the same programme
If you decide to interrupt your programme in order to apply for re-enrolement , you should note that you must do so before 1 April, if you plan to apply for re-enrolment in the same programme later in the same year commencing on 1 September.
That is because at least 5 months need to pass before it is possible to re-register for the same programme. Read more about the rules concerning re-enrolment.
If you instead want to apply for another course
You are of course free to withdraw from your programme and apply for entry into another. You only need to make sure to apply before the deadline and make sure that you fulfil the admission requirements.
