My roomies could tell you a bit more about that than I can, but from what I've seen so far 1N1 is pretty good stuff. Do a lot of looking at imagery, figuring out exactly what's there, all kinds of stuff. It's pretty well focused.
Boot camp, well, heh heh.
It's a tad different now from when I went. They re-arranged a few things, but it's still 6.5 weeks. Depends on what squadron you end up in as to how you'll get treated. Pray for the 322. They follow the rules. They don't hit you, etc. The others, well, take a bit of leeway. 322 trains you to be disciplined because you respect/admire (I kid you not) your MTIs, not because you're afraid they'll kill you.
For starters, the first rule of basic: You Are Wrong. I don't care what you're doing, you're wrong. Second rule of basic: Don't Buck the System. Since you're wrong, do you really think you can argue with your MTI and win?
Third rule: one of the air force core values is "service before self." In basic, it means nothing. Take care of your stuff, then help other people. Volunteering isn't that bad of a deal. In fact, it can be good sometimes. Volunteer for stuff. Stay away from laundry crew. KP duty is good stuff. You get time to eat that way. Run. Do pushpus and situps. Lots of them. You want to be able to do at least 45 of each in a minute, and run 1.5 miles in 11:45 or less (10:00 is good)
Practice eating quickly, without talking. You'll get about 5 minutes to eat if you're lucky. Learn what ranks are what. ie, staff sergeant is E-5, LT Colonel is O-5, etc.
Theres more, but I can't really think of anything at the moment. Any specific questions you have, fire away.
