How long should an essay be in a 1 hour exam?

It's usually worth drawing up a quick timetable for the exam. Say there are three questions in three hours, you should spend one hour on each (assuming the same number of points to be gained). You may need 10 or even 15 minutes for a good essay plan, leaving you with about 45 minutes to write up the essay.
