you're perfectly entitled to backup career(s) A1, A2, A3 (...!) to fund the dream of plan B - plain common sense and an insurance against career suicide. it's evidence that you're pro-active about your career choices.
as long as you can back up why you jumped x for y. and lets face it, quitting the course for a bigger, better one after only a few weeks (rather than a few years as does happen) is no biggie if you've thought about it properly. CTC themselves were advocating to some guy on the old thread that he try a few months of uni then re-apply and drop out to fly.
you can prove to them you're sufficiently motivated for pilot above Y by knowing the course, industry, partners and company inside out for the interview. remember, you have a PPL and this is a good sign of your commitment to flying.
as for being a student right now, do ask them but i doubt it matters, see the perma-debate on 'uni vs flying training'
