Forget going to ATP. I just finished my atp written using Shepard air and it worked out for me. All you have to do is study their online prep and study the way they instruct you too and you should be fine. I studied for 3 1/2 weeks and took the test and made an 80%. Granted its not 90% or 100% but the idea is to pass the test before the deadline. Mission Accomplished..........
