Once you have completed all the necessary courses and your internship, you have not yet graduated. In order for you to graduation you will have to apply for graduation. You can do so by filling out a form on RadboudNet, located under 'Requests, forms and graduation'.
You may apply for graduation once all exam results have been processed in Osiris. Please do this as soon as possible once allowed, so you won't have any unnecessary delays. There is only one graduation date per month (except for July, which has none) and you are not allowed to commence with any Master's without graduation from the Bachelor's degree.
