Some students have asked if it is OK to submit more than five pages of project proposal. You may write longer, if it is spent on actual plans and decisions for the thesis work. Make certain that you don't write too much introduction. A good rule of thumb is that the research question should be at the first page.
And don't feel that you have to. Three pages can be enough.
The library courses will be held in "Grupperom 9", Georg Sverdrups hus. One flight of stairs up from the coffee bar. (Opposite from the part of the building with all the books)
