I took the LSAT this past June and if you can afford it, take a prep course, there should be classes open still because the next test is in October. If you cannot afford the classes b/c they are crazy expensive, I recommend the following prep books:
Powerscore's Logic Games Bible
Powerscore's Logical Reasoning Bible
LSAT 10 Actual Exams, use as practice exams, only looks at tests from 2000 onward.
Barron's LSAT prep book
Good luck! The key to this test is getting used to the questions and pacing accordingly and practice practice practice!
