I read the powerscore bible for it and went from getting 10-12 per section right to getting 18-23 every time.
FWIW, I wish I had done the powerscore bible prior to taking the LSAT. If I had to re-take, I'd do the Powerscore bible, first.
I'm all over the place with these logic games. Some I can get literally every question right, others I can get like 1/5. Overall I am scored 7-11 right out of 24. Which really sucks. If I don't improve dramatically I doubt I'll even take the test.
