tache you are young and intelligent. Review the degrees on offer at Kingston and have a rethink if there is anything else that interests you. There are other areas that can still require involvement with aircraft, aerodynamics, design etc etc.
If you really can't get this myth of working on aircraft out of your head then last resort is straight to Kingston on the B licence degree course. It will at least buy you time.
Don't listen to the bull**** about not having any experience from less intelligent individuals with 20 years experience compared to your none who think they are clever joking about your lack of practical skills.
Aircraft maintenance from an engineers perspective is spiralling down. It is irresponsible of old sweats to try and convince you that it isn't.
