This is a book of 10 real LSAT PrepTests published by the Law School Admission Council. They were administered from October 1999 - October 2002.
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. As such, 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. I recommend these exams to all of my students. However, you'll need many more LSAT PrepTests than those 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.)
