So long as you're an "in-state" student, the fees for the ground school are not substantial. Each is normally 3 credit hours, with each credit hour costing the student about $50. So you'd be paying about $150 per class, which financial aid should cover. The biggest cost to worry about, of course, is the flight training. However, if you've already been approved for an alternative loan, thats not an issue.
My experience with financial aid is limited. However, I have heard from colleagues that it can be fairly generous and cover all class and material costs with some left over. This is of course dependant on how much financial need you can demonstrate.
There are numerous people at BCC who could do a better job explaining it all and helping you out. The number one person you'd want to contact is the admissions co-ordinator. I don't have her number handy, but it shouldn't be difficult to look up on BCC's website.
