Post Number 2? You've lost me there, sorry!
Well, I can answer (from LOTS of personal experience on the recruiting side!) but only from the point of view of OUR Air Force (RNZAF) - but I would (hopefully) assume that's it similar.
Yes, maths and science are very important! Although, if they are THAT strong, they may ask you to work as Navigator, or Air Warfare Specialist!
Working with numbers, thinking logically and quickly, and having a fundamental understanding of the workings in progress around you (ie the physics side) are very important in the air - and I would imagine even more so if you are blasting around at 400kts.
As for the asthma, well, I don't know this for sure, but my guess would be "sorry chap" unless you can show that you haven't been afflicted by it in a very very long time.
I am sure that as more people read this you will get a better idea, but I hope this helps in the meantime.
Good luck
KC
