I was in class 503-08 (May of '08), and I know a lot has changed since with respect to particulars. It blows my mind that the gates and the standards for them are actually briefed now, but that brings me to the one piece of advice I would like to add to that presented thus far:
Do not try to game SFAS. This goes along with assessing yourself out. You are always being evaluated. Trying to calculate how much of an effort you need to put forth to get a "GO"or a good eval for an event and then metering out your effort and expending the minimum you deem necessary is a good way to skyline yourself as unsuitable. There were plenty of folks in my class that I heard strategizing their way around the events and through SFAS that found themselves standing in the non-select formation with sad faces on the last day.
On second thought, if any of that would have seemed like a good idea to you in the first place...go right ahead.
