this is my first time taking LSAT and i was planning to do the test this coming june 2009 (as i figured that i may not be ready for the february 2009 test). i have been looking for some of the book materials that i can use to study and i found a book, i mean the only book about LSAT exam. it's McGraw-Hill's LSAT book and i was wondering if they are good enough. what else do i need?
