In an oral exam the examiner will ask you a question about a programme, a paper or a project you are familiar with.
The purpose of oral exams is to confirm a student´s knowledge of a subject matter and/or confirm a grade.
There are two types of oral exams:
Closed answer oral exams: You are expected to have learnt and be able to reproduce the content in a programme.
Good memorization skills are an advantage in this type of oral exams. There us little scope for creativity.
Open answer oral exams: There are no set answers to questions. Answers are based to a large extent on the candidate´s personal experience and their ability to prioritize information, analyze data, summarize information and think critically.
Completely different answers could be equally valid.
