I did things a little differently and went to university then applied for ctc half way through my 1st year. Got on the course and left after my exams at the end of my fresher year.
Im the 3rd 21 year old in the last 4 posts to be flying a 757 (well, on the 29th june i will be anyway), and certainly dont regret leaving uni to come on the CTC scheme.
