Yeah, true that. I didn't do the UMAT but I had quite a few friends who did. One worked her butt off because she really wanted to get into Med. and got a pretty disappointing score. The other one did it just because he could, winged it, and got a really good score that could get him into Med. if he wanted - though he doesn't want to. I don't think the UMAT's a very good indicator of hard work which is a shame because I know quite a lot of people who would make amazing doctors (or any other profession that requires a good UMAT score) through sheer hard work. I could be wrong here, but it shouldn't be about somebody's ability to pick out the odd shape or whatever else. For that matter, I don't think it's necessarily a very good indicator of somebody's intelligence either. I know somebody who got a 99 raw as an ENTER and is pretty much the lovechild of Einstein and well, whoever else is smart hahaha and got a pretty shoddy UMAT score.
One friend summed up the UMAT as: 'you've either got it, or you don't.' It sounded a bit defeatist to me but I really can't judge since I haven't done it myself.
