Failing my exams. Any advise?

Maybe you could try college instead, its a lot different to school. You could maybe take up some course that can help you get a job your interested in eg. mechanics,art etc. or try for an apprenticeship if you don't want to finish your a-levels. Just be careful though, i completed my a-levels and got D's in them all so i thought i'd have a break from education and earn some money and 3yrs 8 months later im still stacking shelves in a supermarket going brain dead.
