I used to go there, at JU. Overall, most of the DCA staff are pretty good people. JU left a really bad taste in my mouth. You need to realize, before you start - you will pay a couple thousand dollars more, each semester, than what you were quoted. DCA quotes their minimum prices - and those prices are locked for the next 2-3 years! We had people asking them to raise their prices so that they could get more money from their student loan companies, and DCA can't b/c they're under a contract that won't let them raise their prices. Also, raising their prices would drive away potential students - so, you can see their predicament.
Just be sure that you have looked at all possible options as you go into DCA. There are other ways to get your pilot qual's and your education, rather than looking for 2-year or 4-year Aviation Degrees. It may be for you, it may not, just be sure to look at lots of different options - they're out there.
