Perfect 2024 reference guide

Needed a revised 2024 edition and this includes a statutory supplement. I’ve purchased other books from this company and they’ve all been exactly what I was looking for. Highly recommend!!

Don't Like the Typeface
Format: Paperback
I'm sure the information is fine but the typeface is annoying to me compared to the Michigan Legal Publishing reference books I usually buy. I won't make this mistake again.

Good Additional Book for Law Students
Format: Paperback
My husband needed this book as one of his required course books and he loved it. He said it explained everything so well and even provided step by step examples on how to construct an MPT task.
Taking the Bar Exam more than once is not worth it, spend the money it's well worth it and if you use this book you can increase your odds to score better on the writing portion of the Bar Exam.
