In a fit of compulsiveness, I bought all three of the Law School Admission Council's "10 AO LSAT" books. (The first is "10 AO LSATS", followed by "10 More AO LSATs" and now this, "10 Next AO LSATs."). All three books contain offcially released, actual LSATs. However, if only buying one, I would say that this is the best choice. The tests are newer; moreover, it seems to me that the "games and "logic" sections of the current LSAT, though ostensibly the same as when first introduced in 1994, have been made slightly easier. If you just read the first book, you may be needlessly scared and discouraged. With this book and to a lesser extent the second book, you will at least not have unjustified anxiety. This is still a TOUGH test, but but no longer quite the nightmare it was back in the mid 90s.
