A new addition to the PreTest product line, this review book covers only those topics in biochemistry which, through the author's experience, market research and in-depth reviewing were viewed by medical students as being most difficult to comprehend. The text is organized by general concepts, which are then subdivided in order of increasing complexity. Each section begins with a short summary of key points. The book's unique approach stresses the mastering of fundamental concepts instead of just the memorization of facts. Thus the student is encouraged to reason through problems, and to better retain what he/she learns in the course. This text can be used in concert with the sixth edition of PreTest Biochemistry to form an excellent review source for students taking biochemistry exams or Part I of the National Board Exam.
