The ACE program is probably the most difficult program in the area, I said this because I finished it. As far as disorganized, I agree, however; I also have friends who goes to the Villanova and UPenn program, they also complained about their programs in terms of organization, knowledge of the instructors, etc. My point is, you will not find a perfect program. High drop out rate, yes, very high drop out rate, like I said before, it's a very difficult program. BUT, let me say this, the reason the drop out rate is so high, it's because they really prepare you. You can't expect to go through the ACE program with 86 credits in 11 months, and have over 99% nclex passing rate to be easy, right?
One more thing, sometimes I get asked what program did I go to, I told them the ACE program, and they said, the ACE program from Drexel? and I said yes, they usually replied "wow, I don't know how you do it".
