Shouldn't you get part 66 theory credits after doing FdSc with Kingston Uni or directly with Newcastle?
Was that foundation degree with Glamorgan Uni or elsewhere?
If you have FdSc, there's fairly recent thread about getting job or place to study in aircraft eng. There's bunch of answers.
I checked out Kingston again after the posts and found out it's OK or better than I though. Just that one would probably have to do intro year, so after 3 years one would get FdSc instead of BSc like at Glam Uni. OTOH, they do offer BEng (which should be 'beng on'

) as top-up after FdSc.
Why wouldn't you get hands-on experience when doing foundation degree in airmech? Isn't that a bit contradictory? Kingston work with most (maybe) major players in the field and Glam Uni do their BSc together with Barry College (ICAT) at Cardiff airport.
After all, shouldn't you know all the ins and outs having done FdSc already??
