Summary: This was the best book out of three for comprehensiveness.
Review: This book provided the most useful methods of preparing for each portion of Battery Exam 470. There was adequate summary of learning techniques, very useful tips and most importantly sufficient practice sections, exams to best prepare by doing questions. Although not as many address checking and memory address sections as Bautista's book, I would recommend this one book of the three I purchased.
