I'm 19 and currently doing the last year of my A-Levels, I've taken Biology, Chemistry and Computing, and it looks like I will end up with 3 B's overall.I was wondering if it's possible to be trained by an airline straight out of school, or if it would be better to go to university first before looking to become a pilot? I was planning on studying Medicinal Chemistry which is completely unrelated to aviation, would that be a problem?I'm also short-sighted and have a red-green colour deficiency, how will that effect my chances of becoming a pilot?Before applying to an airline, would I need a PPL?Thank You,-Sam :)
