The LSAT is an interesting test. One big section is "analytical reasoning", which has you solving logic games. These are actually kind of fun.
After I took the LSAT, and scored pretty well (99.6 percentile), including a perfect score on analytical reasoning, I was in the supermarket and saw at the magazine rack, down in the section with the crossword puzzle magazines, a magazine of logic puzzles just like those from the LSAT. Based on the ads in it, the main audience for this was old ladies.
I bought it, and decided to start with a puzzle marked as hard, figuring it would be easy for me--I had just aced these things on the LSAT, after all, a test designed to make distinctions among the brightest students in the country. Obviously, anything old ladies could handle I could handle almost in my sleep.
It completely kicked my ass. So did all the medium puzzles. I think I was able to do a couple easy ones, with a lot of effort.

> The heads of Bletchley Park next looked for women who were linguists, mathematicians, and even crossword experts. In 1942 the Daily Telegraph hosted a competition where a cryptic crossword was to be solved within 12 minutes. Winners were approached by the military and some were recruited to work at Bletchley Park, as these individuals were thought to have strong lateral thinking skills, important for codebreaking.
(Although they are not that far from a few other majors, it is an interesting read in any case.)
