Dude, you're asking for a definition that just can't be given. You might end up in a class full of slack a$$es or a class full of Chuck Yeager's. You can't control that, so why get your panties in a bunch over it? Like I said before, worry about the things you can control. Studying, chair flying, and being fully prepared every time you sit down with an IP and brief to fly.
When you show up on day one, there will be one thing made abundantly clear. Whatever you end up with, YOU have to earn. Are you really expecting someone to give you a laundry list of criteria that will guarantee you a 38? I hate to be the bearer of bad news, but that just isn't going to happen.
Your going to find that there isn't a whole lot of difference between the guys who fly big slow airplanes vs. those that fly little fast airplanes. They all got wings, and they ALL had to work hard to get them.
Relax, have a beer, and just be ready to do your part. Good luck.
