Well said...for any guys w/ a fair amount of prior time, like myself, this is what you're going to learn, since you should already know how to fly. Learn the BOLDFACE, how to put up with AETC queep (which IFS IPs do a fantastic job of imitating), how to do a tabletop EP, and how to design a wildly inappropriate (but on the surface, clean) class patch that will still get approved.
That PFT is no joke. If you're not from the Academy, and run an average 1.5 mile time (11:30 or slower), you're in danger of failing if they're using the new PT standards. Not that it's a real PT test that'll end up on your record, but prepare accordingly...
Finally, some common sense from one of the many people that didn't struggle at IFS. Here's some real advice: If you have a lot of prior time, don't tell anyone. Don't raise your hand when they ask who the PPL/Comm/CFI-rated guys in the audience are, and definitely don't tell your IPs unless they bring it up or notice. FWIW, the guy in your class with the most prior hours will be the SRO. That job sucks, but is easy to do well.
If you you have some prior time (solo-PPL), don't take it for granted as it probably won't help that much. Learn the BF/Ops Limits cold, but don't stress about it. It shouldn't take more than a couple of hours to learn. Practice writing it down while sitting at "modified attention," using a checklist as a clipboard, and giving yourself a 10 minute time limit. That's the best practice you'll get...and if you show up day 1 and some poor soul in your class doesn't have a kneeboard to write on, don't be a douche and help the guy out.
For everyone else, if you have no time, don't stress out. Study Gleim, AOPA, or Sporty's PPL test bank (~600 questions or so) until you know all the answers (might take some time). Once you have that down, you'll ace the academics. Know the BF before you show up. Pay attention during ground week and bank some sleep, and study what the IPs tell you to do. The In-Flt Guide and the checklist should be your bible starting week two. After your dollar ride, start chairflying...but focus on procedures, radio calls, checklists, and timing. Practicing steep turns and sight pictures in a chair won't make you a better pilot. Memorizing radio calls so you don't have to think about them while you're trying to fly will.
Finally, bring a computer/iPad w/ plenty of movies on it and a good book. Hell, I even brought my Xbox (not recommended...). Go to the store your first day there (bring a car if able) and buy some booze and snacks. Settle into your little cave and learn to relax! Take Saturday off, go catch a baseball game, go hiking, or go out to eat. Studying for 6 hours a day won't help you if you're constantly stressing out. The guys in my class who washed out didn't do so because they weren't smart enough or good enough. They failed because they couldn't take the implied stress that's imposed on you. Enjoy your 3-6 weeks in Pueblo, learn what you can, BS the rest, cooperate to graduate (help your bros), and move on. Good luck!
Edit: "don't be a douche and help the guy out" = "help the guy out"
