''Do you hold a full UK driving License?''
If its not important, why would they ask? and besides in 99% sure you need one to potentially be an airline pilot (travelling from home to work etc). Well, i am about to start a 1 week intensive Pass course (at the cost of £750 cringe!).
Least of your worries for now, it is certainly not a pre-requisite - It would be good to have though just so that you can drive in NZ otherwise you'll be dependant upon others to ship you to the airport and to town etc.
As for not being intelligent enough to pass phase 2, I wouldn't worry about it... the maths test is really simple and they even let you re-attempt it at phase 3 if you only just fail it (no, I didn't fail it before you ask
) - can't say fairer than that! The rest is just down to aptitude and I wouldn't really correlate that with intelligence. If you require a bib every time you eat and have a nasty habit of walking into lamposts then maybe you won't do so well, but I really wouldn't spend much time worrying about this phase. I'm not sure of specific pass rates but I think it's something around half get through...
Phase 3 is, in my opinion, the make or break phase and by far the most challenging - after that you're more or less a shoe in unless you insult the phase 4 instructor's mother/have the flying ability of a penguin.
Captain Spam Can - he is correct...
