If you only take 10 PrepTests before the real LSAT, these shouldn't be the tests you take. Get the newest tests you can beginning with PrepTest 39. They aren't yet sold in a book, so you'll be buying individual test booklets. If you have time to finish all of those then add this book.

It contains modern LSATs (post December 1995). Even though the tests are newer you'll still notice some slight variation between these tests and the real LSAT you'll take. That said, it's an excellent study aid, it's cost effective, and it's easier to order than a bunch of seperate tests.

This book contains:
PrepTest 29; October 1999
PrepTest 30; December 1999
PrepTest 31; June 2000
PrepTest 32; October 2000
PrepTest 33; December 2000
PrepTest 34; June 2001
PrepTest 35; October 2001
PrepTest 36; December 2001
PrepTest 37; June 2002
PrepTest 38; October 2002

The book contains the newest tests released and is a definite necessity to studying for the LSAT. Although it does not contain answer explanations, it is great practice to take as many of these as possible before the real thing. I used them in addition to a more in-depth studying tool and found that together I had great preparation and was totally relaxed and ready on test day.

Published by the LSAC, the group who administer the LSAT, this book is comprised of ten older tests from 1999 - 2002. In my opinion, nothing is better than taking old tests under simulated conditions, so this book fits the bill perfectly. I would highly recommend it to anyone preparing for the LSAT.

This packet is the newest of three such packets released by LSAC, and is invaluable to anyone studying for the LSAT. I highly recommend avoiding at all costs any practice test that is not real LSAT released by LSAC; the practice tests manufactured by Kaplan, Barron's, Princeton Review and the like tend to be over-simplified, and often have little in common with the actual LSAT.

Although I recommend taking as many practice LSATs as humanly possible in preparation for the real thing, if you are short on time, get this packet instead of the previous two. The test has changed a lot over the years, and in most instances, has become more difficult; I find scoring 178 on a test from the mid-nineties to be less challenging than scoring a 170 on a test from last year.

It is true that this packet simply contains past LSATs with their answer keys, and no explanation for why the right answer is the right answer. Unless you feel as extremely unfamiliar with the types of questions on the LSAT, however, that there are no explanations is probably a plus: figuring out why your answer to a question was wrong is actually more valuable than simply getting the question right. Having another book handy which explains the test and question types--I recommend Kaplan's--is extremely beneficial, though.
And good luck to all future LSAT takers!

All this book is is ten old LSAT tests and answer keys. There is a short description of the test at the begining of the book, but no study materials other than the tests and keys. And no explanations of why answers are correct. If you have looked at a sample LSAT test then you already know that learning facts is not going to help. The test mostly goes on logic and uses puzzles and short questions to test your logic. There is also a reading comprehension section. So studying isn't a big issue because there is nothing to memorize. However taking practice tests will familiarize you with the test and reaquaint you with the standardized test not seen since highschool. So this is an excellent way to prepare for the LSAT.

I recommend getting one of these packages of ten LSAT tests or a triple pack. I have looked through other study books at the bookstore and I don't feel that they are that helpful: Practice tests tend to be dumbed down compared to old LSATs and the study strategies laid out in the books I looked through were not that profound. In terms of having an explanation of why an answer is correct it may be better to just look at the question and the correct answer and figure it out for yourself. This way you are thinking through things as you will when you are actually taking the test. (If you want explanations of answers then LSAC also puts out triple preps, in which some of the answers are explained. The cost per test for the triple preps is comparable here.)

Basically here you are getting 10 old LSATS and answer keys. There are also two other similar books (10 Actual Official LSATS and 10 More Actual, Official LSATs). Out of the three this one (Next 10 Actual, Official LSATS) is most recent, so if you are only getting one then get this one.
