The title of the book is a play on the title of a classic book about the art of negotiation, called _Getting to Yes_. Implicit in _Getting to Maybe_ is that, unlike a negotiation, performance on law school exams does not require an exact answer or resolution.
The method by which these law professors explain this concept is especially interesting. In connection with their academic research, they propose to break down law school exams into small components, and thoroughly analyze those components. The result is a very substantial and comprehensive analysis of the structure of law school exams and the skills required to do well on these exams.
You may be asking how the professors purport to explain _all_ law school exams, for surely there are professors for whose exams these methods will not work. These professors make the interesting point that in the United States, law education is fairly uniform, and, therefore, the skills required to perform well on law school exams are fairly uniform, as well.
I read this book prior to starting law school. I found it useful primarily because I have read a number of other books about legal reasoning and the study of law and the law school experience that are more basic than the material in this book. If this is your first book regarding the study of law or peformance in law school, I would advise putting it aside in favor of a book offering a broader overview of law, its study, and law school.
