Below is a list of some old exams. Some include solutions. You make a big mistake if you look at the solution sheet before you have made the question yourself. That way, you may mistakenly think you are able to do them when you are not.

The solutions also show how credit is further subdivided among the parts of the questions. In case you do not know how to answer a question during a test, try to guess what parts would be involved. Then try to answer those parts as well as you can to get partial credit.
