Not everyone who takes the LSAT realizes that it is far different from the SAT in terms of taking it a second time. I remember when I took the SAT the first time I figured if I didn't do well I'd just take it again. I've been in a military environment for the past 12 years (in the JAG office with lawyers, luckily) and I know that unless there's someone in your life to stress the importance of the LSAT, you simply won't know. Last year, when I decided to take the LSAT, I didn't know how important it was or that I needed to really study for it, etc. until one of the young JAGs pulled me aside and told me. If I had been working on the flightline instead of the legal office, I can guarantee you I would not have been given that advice. Military people usually take distance learning courses or classes on base offered by colleges like OU and UMUC. The LSAT buzz that goes around on traditional campuses just isn't there for non-traditional students like military members.
Of course, I can only speak from my own experience. I just got back from a 5-year tour in Germany and the buzz on the base was about the mission and upcoming exercises, not grad school entrance exams (even though many people take classes on base). What really drove it home for me was last weekend I did my reserve drill and had lunch with a sergeant who's taking the LSAT in the fall. His "academic advisor" told him to take it cold to "get a feel" for the test and to sign up under a false identity to keep from having a bad score stick to him. And she assured him that he can always just take it again (like the SAT). I was shocked! Many of us just live in a bubble, I guess.
