I attended it 4 years ago.
Things I learned:
Bring a semiauto 22 with 10rd detachable mags. No bolt actions.
Sight your gun in at 25 yards BEFORE ATTENDING. Please.
Get the proper GI web sling. Skip the leather one.
Use an inflatable camping mat or similar pad.
Peep sights are a big plus, especially if your eyesight isn't all that.
Electronic muffs are very helpful for hearing range commands yelled from 50 yards away.
Do some stretching exercises before the class. On the second day its 'standing, sitting, prone...standing sitting prone'...all day.
Good luck, hope you do better hitting those little squares than I did.
Not mine, but gives you an idea.
