In theory, it is possible to move up from the 60 credit Master to the 120 credit Master providing all the core subjects from the 120 credit Master are added to the programme (including a new dissertation of 28 credits and the dissertation seminar) together with two courses from the research focus of the 120 credit Master which have not already been taken for the 60 credit programme.  75 additional credits are necessary.  

In practice, however, this really does not represent the best way of moving up and will also be very difficult to achieve in terms of both the organization of each semester and of timetabling. For these reasons, students are strongly discouraged from moving up in this way.
