The modules are given in one week as all the lecturers come from outside. It is of course good to have lecturers from all around Europe, but not having the lecturers around is a very disadvantage. All you can do about your questions is to ask them via e-mail, but in the exam, if you have any questions, there is noone...
But the advantage of this compact modules is that, once you pass the exam, handle the report, it is completely over, so you can concentrate on only one subject each time.
So far so good, I am happy about the modules I had, but I still think that if the lecturers could have been around, it would feel more like a university...
