This preparation aid for the Law School Admission Test is a shorter, more compact version of Barron's recently updated large manual, How to Prepare for the LSAT, 11th Edition. The Pass Key version presents three full-length model tests with all questions answered and explained, plus a helpful analysis of the test's four question reading comprehension, analytical reasoning, logical reasoning, and writing sample. Both the analytical reasoning and essay-writing sections have been revised and updated in this edition to reflect the latest LSATs.
