Master’s admissions: exceptional circumstances
The University is providing an option for final year bachelor’s students and pre-master’s students who have encountered a study delay because of the corona measures and wish to begin a master’s programme in the 2020-2021 academic year. For these master’s specialisations this means that in exceptional circumstances you will be able to carry out assignments and sit exams in September. This will enable you to catch up on courses that you have missed so you can complete your bachelor’s programme before 1 October 2020. You will be able to start the master’s programme on 1 September 2020 (with retroactive effect) without a study delay.
In order to minimise the risk of study delay in your master’s programme, the Programme Board would like you to have completed your bachelor’s programme before you start the master’s. If you are not going to be able to complete your bachelor’s programme before the end of the academic year 2019-20, please focus on the starting date of 1 February 2021.
