Most of the scoring is based on how well they do while in a leadership position during an infantry patrol and while under serious sleep deprivation. It used to be fairly common for a young healthy 11B to lose 20 or more pounds during the course. Peer evaluations are a big part of it too. Every member is graded by the other members of his platoon. If you're a dirtbag who goes to sleep on guard or steals food or doesn't pull your weight the peer evals will get you.
