I heard the main selections process was a set of "rolling boards" wherein if you weren't selected the first time your packet was reviewed, you were bumped to the second board, then third, etc. So, the earlier your package is in the better! I'm not quite sure of the steps, but you see a Blue & Gold officer, get your official packet turned in, do your physical test, get medical testing, and finally get reviewed by the admissions board. Then the real "fun" begins :-D
