I did the test cold, expecting it to be in-situ practice for a 'real' test which I anticipated to write a year later. I scored over 170 easily. I later trained to become an LSAT instructor on the basis of my scores and realized I didn't have any aptitude for it because none of my strategies for dealing with the test were explicit - they were just my test taking routine. If you did logic puzzles for fun as a kid and read enough to develop a large vocabulary, good test taking practices will take you the rest of the way. For what it's worth, in my experience most of the kids who did the LSAT coming from the sciences considered it a joke and prepared minimally with good results. They, however, constituted maybe 1/100th of the test takers.
