The Patent Bar Exam is a very difficult exam and if one studied the first half of this book and memorized it, there is no way that a person would pass the exam. This book could have given some very useful tips on how to study the 3,000 page MPEP, of which the tester is responsible for knowledge of its context. The second half of the book has copies of exams that can be obtained free on-line. There is a need for a better book.
