According to the SORB website, the actual requirements for applicants already in the army is:
Must score a minimum of 229 points on the Army Physical Fitness Test (APFT), with no less than 60 points on any event, using the standards for age group 17-21.

For 18x candidates, the numbers may be a bit different.
http://www.goarmy.com/special_forces...d_benefits.jsp says that you only need a 229 without age group specifications. Although, a less reliable source from
http://usmilitary.about.com/od/enlistedjobs/a/18x_2.htm says that it is in the 17-21 age group.
Either way, from reading nearly every post on the forum relating to the PT test and talking with QPs and other candidates, you should be shooting for the 300 everytime (
http://www.professionalsoldiers.com/...read.php?t=991 ). Don't worry about what the minimum score is; you shouldn't be aiming for something that low. Also, your profile says that you are a college student. If you are of traditional age, shouldn't you be in the 17-21 year old age group anyway?
According to an earlier thread posted about the statistics on passing selection with age groups, ruck times, and PT scores, those with lower PT scores simply have a harder time passing selection.
I hope that this at least clears up some of your questions. I am sure that a more qualified person to answer this question will post shortly.
Now back to PT (at least letting my body regen right now).
