Thanks for the replies, but I'm not sure I made myself clear enough. It appears some schools have set schedules and that if you embark upon their course, you will have to work with their schedule, i.e. Cranfield, where it is not possible to complete the exams in under 9 months with them.
So, is there a school that will help me knock some time off this 9 month period without being silly about it, i.e. 70 hrs a week is clearly not really a sensible option for most.
