this is weird, i thought i replied to this question but i guess not...anyways, i'm currently taking the kaplan course, and the kaplan guarantee is not for the score you WANT but it's a relation to your baseline score which you get when you take the diagnostic exam on the first day. they guarantee you a higher score on the actual OAT/MCAT/DAT/etc than that. of course that'll happen though, cuz their diags are pretty darn hard!! i took them 4 times already (kaplan has a lot of free exams at my school...and they always use the same test, the diagnostic test, so i've seen it so many times). the 4th time i got a 400 cuz i remembered many of the answers, but i think the first time i got a 320 or something. there's catches to the guarantee too...but they're pretty easy - you just have to go to every class and do all the homework (which is a lot of homework, but it's do-able, plus you'd better do it if you're paying $1000 for this stuff =P).
