This book provided me the foundation to do well on law school exams. As you've probably read or heard elsewhere, your grade in a law school class is most often determined by your performance on one exam at the end of the semester. In no small part, I graduated in the top 10% of my law school class and owe my job in biglaw to my reading this book during the summer leading up to my 1L year. It's worth the $30 and your time. Read it again before your exams in each of the first two semesters.
