There are many books that try to prepare you for the LSAT, ranging from free (in your library) to $189 for the PowerScore LSAT Bible Trilogy (listed retail price, discounts available). These books tend to be bulky–the Kaplan LSAT Premier 2016 is a modest 933 pages. while each book of the PowerScore Trilogy is near that.
The Official LSAT Superprep retails for $28, costs $18.30 at Amazon, is easily available in “used” condition for under $3.00, and is available for free at most libraries. There are only 63 pages of instruction–the remaining 350 pages are three complete tests with explanations for each answer. It is the “Official” LSAT book because it is published the Law School Admission Council, the producers of the LSAT.
The reason it is so short is that unlike almost all the other prep materials on the market, the “Official LSAT Superprep” confines itself to explaining the test rather than teaching specific techniques to “crack” the LSAT (Princeton Review), “beat” the LSAT (out of print), “hack” the LSAT (website here), or “nuke” the LSAT.
The strength of such a short book is that everything it includes is well-nigh essential. A student who is struggling with one particular type of logical reasoning question might have to read 70 pages to see how Kaplan covers it in their LSAT Premier book. The Official LSAT Superprep covers it in three pages.
If you can afford a tutor, the Official LSAT Superprep may be a far more efficient use of your time than any of the bulkier books. If you can grasp a concept in two pages, you don’t need 68 more pages of text and exercises to get it better. If you can’t grasp the concept, it will show up quickly when you take a practice test. A tutor can then zero in on what you didn’t understand in a way that a textbook never can.
If you can’t afford a tutor, this book is nowhere near what you need to succeed. It tells you what you need to do but doesn’t tell you how to do it.
