As a practising teacher, what do you get out of marking exams?

When you examine, you have access to a whole range of papers.  You can see the pitfalls of certain questions so you can advise your own students and share the learning within the school.  I think also sometimes, when you have been teaching texts for a long time, you do become a little bit stale perhaps in the way you are delivering them.  I find that in reading this range of papers you are given fresh new ideas that you can share with other colleagues.  This enables you to come ot the paper, and come to teaching with a fresh perspective.
