These are good books, as long as one remembers that the Bar Association changed the questions on the MBE recently, due to allegations that people were sitting for the Bar Exam for the sole purpose of memorizing the questions and parroting them back to companies like BarBri and PMBR. So, while these are excellent review questions, while I did every one in the book, I was still shocked to see how the questions on the real exam were phrased... so don't assume just because you score high on these, you're gold.
Also remember, this book does not address the essay sections of the exam, and does not apply to the State of Washington.
