The computer bit is in stage two. Im assuming you will sail through stage1
To be honest before my stage1 all I did was get my brain back into doing some maths. The RAF had numbed my brain.
Think it is the FEAST tests for stage two now which are meant to be pretty cool but you cant really prepare for them. I suppose you could be cheeky and ask if you can play on the aptitude tests at cranwell for ATC and FC that might be helpfull?
PM me if you want. I have loads of info i got from going through. Interview questions etc.
