AIM is coming up, and I have a few questions for anyone who may have been there in the past. 1) I've read that a sizable number of attendees drop out. I by no means plan to give into whatever pressure may make people to do so, but I was wondering why exactly so many people cannot make it through. 2) Is there a CFA at AIM, and if so is it usable for SA applications (as in, is it like USAFA SS's CFA where it's just "practice" and cannot count on an SA application, or like USMA SLE's CFA where it does count)? 3) How important is swimming ability? I obviously know how to swim, but can't say I've ever really practiced it seriously. 4) Is there anything else I should know before I commit to going? Thanks!
