Lozzo - yes it is possible to be rejected at the application form stage! I accidently put 4 GCSEs on my application form even though that wasn't the case (massive typo!) and received an email stating I hadn't got through to stage 1! A phone call later and a 2nd email was received with a different situation...thankfully!
Paperclips - thankyou! I've just booked the NATS medical - when does the CAA medical take place?
