Obviously this is my experience and it was with Bristol (distance learning) but against better advice I insisted on resitting sooner rather than later, my thinking being that I could turn my 74% into a pass and being all keyed up and well revised I would surely pass second time....wrong!!! There simply wasn't enough time to get ready and when I finally did resit again I went to the exam having re-read the entire syllabus and actually understanding the subject rather than overly relying on feedback to make up for the shortcomings in particular areas. I believe schools know best and if they say 2 months it's worth listenening to, however the CAA will allow you to resit straight away.........if you get the application in in time.
