The exam will be on December 14th at 15.00 (4 hours) in the large study hall at the Physics building (Store fysiske lesesal, Fysikkbygningen). It is very important to be there ahead of time, as you will not be allowed to take the exam if you are too late. Updated information about the exam can be found here.

Old exam exercises can be found here. Some of them are in English, but unfortunately most are only available in Norwegian. Please feel free to come by my office or send me an e-mail if you are having trouble with the language (or anything else related to the course, for that matter).

The exam sets will be available in both Norwegian and English, however, you are only allowed to get one exam set (i.e. either Norwegian or English). I will do two rounds during the exam where y...

If you are using a Mac with the newest operating system (Mac OS Sierra) you may have trouble downloading Riscue. In this case, open your terminal window and type:

sudo spct1 --master -disable

This should fix the problem (which is that Mac wants to make sure you're not installing viruses on your computer, however Riscue is not a virus).

If you have any other problems or questions regarding Riscue, please ask me or Arne B. Huseby (

... is now available in Norwegian and English. The deadline is November 10th.

The assignment is heavily based on the simulation program Riscue which will be presented by Arne Bang Huseby on October 18th. It is therefore highly recommended to attend this lecture.  Nevertheless, the first part of the assignment can be done without knowledge of this program.

Best of luck!

NB: Note that for those taking the course at master level, i.e. STK4405, it is required that you use a mathematics formatting program such as LaTex when submitting this mandatory assignment.

Those taking the course on bachelor level, i.e. STK3305, may choose to write by hand.
