On the surface, the notion that a study guide designed to help people remember (or learn) confused words or words that have been spelled wrong is an odd thing to read. The value of this study guide can be important depending on the type of exam being administered. What if the exam requires reading verbatim quotes from case studies? In this case, learning the various colloquialisms people speak might prove enormously helpful. A better understanding definitely will aid in staying focused during the exam.
