It would not decrease your chances of getting onto the course at all if you went for the 08/09 instead of the 07/08 entry. Masters in Management are often taken by people directly after their Bachelor's degree, but there are also people who use it for a career change, or who like yourself want to understand more of the background to their work. If in doubt, go along to an open day and speak to admissions tutors, but I am sure they will welcome people with a couple of years experience just as much as new graduates.My general advice would be to take the course when you want to. Don't be rushed into going back to uni because of arbitrary deadlines, but equally don't put off learning just because your firm don't want to pay for it.
