what java said ^^ ..my scheduling had more to do with an opening in my AIT and the fact that I skipped the first 8 weeks of AIT having enlisted under the CASP program (ie I was already a licensed medic beforehand/ no need to waste everyones time)
learning the ranking system and D&C ahead of time helped me not waste a lot of time thinking about that shit in BCT
and truth be told..it saved my ass with running because I didnt run and hated running before hand and always sucked shit with distance running
theyve changed it to your recruiter does a pt test on you to see where you're at
I was a pt studette by the time I got to basic
if it makes you feel better plunkey I always had to be taped for the bmi test because I weigh a gazillion lbs
