This is a book of 10 real LSAT PrepTests published by the Law School Admission Council. They were administered from June 1996 - June 1999.
Each PrepTest contains the 4 scored sections of the exam, as well as the writing sample. These PrepTests do not contain comparative reading questions, which were added to the exam in June 2007. If you use this book, you'll want to practice with several newer exams also.

I'm a professional LSAT tutor in NYC, and I also run LSAT Blog. In my experience, I've found that many LSAT books out there choose to make up their own questions rather than pay the licensing fee to the Law School Admission Council to use real questions. However, this practice leaves students woefully unprepared. I can't emphasize enough how important it is to study from REAL LSAT questions, which are exactly what this book provides. However, you may want to focus on more recent exams than the ones provided in this book in order to adequately prepare. (See the tips on my site for more information about what to complete before taking the LSAT.)
