I hate to rain on your parade but I suspect you've been misinformed or misunderstood what was said, is it possible the coll

I know students in many countries do part time work to earn money whilst going through college/uni, but the idea that on leaving school you're going to be able to join an airline and work on a part time basis as an pilot whilst also doing a first degree at college/university is, I suspect, somewhat fanciful.
