I did the 4 day course at All ATP's for my ATP. Took both the ATP and FE written on back to back days. I agree with all the above posts. However, I recently had to retake the FE written as it had expired and used Sheppardair.com. It was only $75 and they do the same thing All ATP's does by removing the Q's you won't see on the tests...Same prep, less $, and from your home computer...I got thru the 50 Q test in 30 min with a 100%. I think they have a money back guarantee.
