I did O levels (at a dire comprehensive in the early 80's), BTEC National Diploma in Buisness and Finance (at a local technical college) and, during that course, a local accountancy firm came to the course and interviewed those of us interested in becoming Chartered Accountants. I won the training contract on offer and I did all my professional training with them - practical experience in their offices and they funded my courses and attendance at Reed College for the examinations.
I have a degree in law, and now work as a translator. I do a fair bit of legal translation so the degree is certainly not wasted, nor is the staying power to read long and boring documents, ability to argue and be assertive in debates.
