I am a former PDTer. The training is intense, BUT doable as long as you know how to fly on instruments. The guys in my class that failed out couldn't fly an ILS to save their lives. They are not there to teach you to fly an approach or hold. They are there to teach you to fly the Dash. Ground school is a fire hose of information, but if you show up having studied the home stuff you will do fine as long as you put in some after class study time. Good luck with your decision, I enjoyed my time there. You will learn a a lot from a lot of guys that have been around for a LONG time.
