Years ago my then wife, a tenured professor at the University of San Diego, decided she wanted to give up teaching and become a lawer and, being on the faculty, she could attend the (then, dunno 'bout now) highly rated law school there free of charge.
Oh, and so could her esposa! She wanted to flee CA to the east coast and drag me with her (HA!) so I took the LSAT there, beligerantly and just for kicks, no prep whatsoever and ended up being accepted into their school of law
. Well, I'm an artist with no desire to be a lawer so the marriage predictably ended (a good thing).
Point is, I think if I'd anxiuosly gotten my panties in a bunch and taken prep courses or whatever, I'd have probably done nowhere as good as I did. As someone posted earlier, one is able to think that way or not and I don't personally think that one can "prepare" one's self to think that way if it's not natural.
But WTF do I know? I'm an artist not a lawer
