The training isn't THAT killer.
If you have 250 hrs, it may be. The AQP training program, as others have stated before, is a condensed/fast-paced program. It was designed for the higher-time applicants (ie. ATP or greater) At this point, they know that you know and understand advanced aircraft systems and have simulator experience. All they do is teach you how to fly the Dash. This is why some ladies/gents have struggled to get through the program.
If you do happen to get picked up by PDT, let me be the first to congradulate you. Just remember "cooperate to graduate" and you will do fine. Do not argue with ANY of the instructors or you will be hosed for the rest of the durration of training. It's "Yes sir, No sir, I'm wrong/you're right sir" and most importantly "thank you sir."
