I have to say that it doesn't really matter what your level of education is. Although I have A-levels and a degree, none are in a subject relevant to aviation, nor were any of them completed to a high standard. You will most likely have to demonstrate to a future employer something in place of that further education, such as solid work/career experience and a continuous interest in flying. Most employers today employ "the person" and not necessarily the exams you passed, although it does pay to do VERY well in the JAA exams and flight tests as that will improve your chances of a job above all the competition!!!
Good Luck!
