Results per page default

The results per page on an exam sets automatically to 10. I usually take 50-100 question exams, so if I want to get to a specific question I have to either browse to it or reset the results per page to a higher level every time. It would be nice to be able to set my default to 50. Also, having a "view all" option would make it faster for exams with more than 50 questions.
