Depending on your academic qualifications you have to follow a premaster programme. You must have successfully completed the entire premaster programme before being admitted to the Master’s degree programme.
The pre-master programme often contains 30 European Credits (30 EC = 840 hours).
For 2/3 you follow courses in methods and techniques, most likely the following:
Introduction to research methodology
Research Methods and Design

The other courses (most of the times 10 EC) depend on your prior education. These courses are assigned by the Admission Committee in your Acceptance Letter.
