just about any one can make it through flight school. other than medical problems (which are relatively rare) the only thing that trips students up is a lack of effort. show up ready to work your tail off and you'll do fine. study way more than you think you have to and if you end of being over-prepared, tailor it back (a little). you'll get plenty of briefs about the actually numbers and what trips up most students when you show up for API, but like OttoWrote8 said, don't worry about the statistics or how everyone else did, worry about yourself and don't let them get rid of you.
