I wasn't quite sure if this was the best place for this question.
If faced with a maths exam where you can choose the questions you do, how do you approach which ones to pick?
I'm interested to see what "frameworks" people have.

I always try to do the tasks first which I am pretty sure I can manage. If I have the feeling that I collected enough points that it is rather sure that I pass the exam then I try to solve tasks which seem to be more difficult and therefore probably give more points.
I think this is the right stategy in order not to become discouraged.
Mabye this isn't exactly what you asked, I can tell you my experience with math olympiad tests like the imo(I didn't go to the imo though),which are exams consisting of 3 questions and 4.5 hours total. What I would do is give half an hour to each quesion first. And once I had a grasp of all of them I would proceed to do the first question (which I would probably manage to do). after that I would do the question 2 or 3 that I felt I had advanced the most during the previous 30 minutes. And if I got that one right I would head on to the remaining question.
