congrats! you are correct, a lot of studying or maybe the most studying you'll do. don't worry about PC. You'll have time to study to qualify after you get through probation. Right now just do your best to pass AC class. Once you're out, there's a good chance you will be sent anywhere from Penn to montauk of greenport. that's is why they require you to have a license and a reliable car. as to whether to drive or DH on a train, you'll have to look at the schedule. Good luck!
