"Sample exam paper"

Some of you are new to this university (/country) and I've had questions on what an exam paper should look like - how much are you supposed to write, etc. For one exam, I handwrote something that could give you an idea.  You may want to leave it unseen until you have attempted to solve that exam though, but in any case: spring 2014. (It also contains some comments, but I think it should be clear what is not supposed to be is clear what should not be in an exam paper.) Also, at some stage someone asked for what is the "bare minimum", and for one exam there is such a note as well - but that exam will be assigned for seminars, I think.

Furthermore:

• Open-book exam. Anything printed or written can be used. Your notes, others' notes, problems, solutions ...
• It is usually a good idea to start on a new sheet of paper for each problem - then you can tear a sheet apart without ruining something else. (But you can also cross out things that should be disregarded - this is not a beauty contest.)
• You can answer in English or Norwegian (/Swedish/Danish, actually). It sometimes even happens that some papers switch language. The exam will be handed out in Norwegian+English to everyone.
• Whatever the language, write legibly. (And yes, of course the graders have already seen enough attempts at writing blurry the parts the candidate does not know anything about. No use.)
