All previous advice spot on. They are still recruiting pilots (I just got in), but not very many. Make sure that you read up on OASC, what you have to do whilst you are there, and what they are looking for in potential officers. I will also repeat what has already been said, just to emphasise these points. Be yourself, that is who you want them to select, and if you want to be a pilot, put only that, and stick to your guns - even if they try and persuade you into putting another branch down.
Good luck, PM me if you need any further questions answering, I was there last December.
TMA.
