The Premise is a conversion from FAA Comm/Inst/Multi to EASA.
If you were to buy just the aviationexam question bank, and not the full BGS home study course
Who would certify you?
If you have a FAA ATP, you can self certify, but not (as I understand it) with just a Comm/Inst/Multi.
The old plan was to self study thru BGS, and do their study week-ends for the certification.
But reading this interesting thread, makes me think it can be done from just from the question bank, if you have some prior experience.
If you aimed at taking one exam a week.
Can you just show up at Gatwick ‘on demand’ when you think you are ready. And pay your £65, to take your test?
Or is it like most things, a giant pain in the butt, with all kind of hoops to jump through.
