Im a loady on heli's mate and i have a few trade mates going for NCA. I went through training with a re-tread who was 34... so don't worry about running out of time! Plus i've recently looked into comissioning. You do not need a-levels to commission from the ranks, but need at least 2 (or equivalent) to join from civvy street. In regards to NCA aircrew, you will need a couple of gcse's probably maths and a science, but of course the more the better for selling yourself to OASC...
Don't sit on your laurels though as someone previously said. Too many people say 'i was going to do that', be the person who did it..you won't regret it!
