back to the subject of the thread. main thing to do is to get your GCSE maths and physics back up to scratch. in addition learn as much about yourself and flybe, read the news section on the flybe website. a lot of airline interview involve a lot of questions from their website so it's that hard to be honest.
as with the degree from OAA, it has very mixed views. personally, i already had a degree upon joining OAA and i never liked distant learning and it's exactly what the course is. my advice is therefore not to base your choice of flying school on a foundation degree
