Book excerpt: For all courses intended to help students prepare for the PTCB pharmacy technician certification exam Certification Exam Review for the Pharmacy Technician has one purpose--to aid students in successfully passing the PTCB national certification exam on the first attempt. Unlike other PTCB study guides, Certification Exam Review for the Pharmacy Technician weights its content to precisely reflect the PTCB's exam weightings, and carefully avoids distracting material not covered on the exam. The Third Edition contains nine all-new chapters that match the new exam blueprint. The authors present five complete practice exams, each with 90 multiple-choice questions designed to closely replicate the actual three-hour PTCB exam experience. All answers are provided, along with clearly explained rationales for each. To provide even more practice, the book also contains three math and two trade/generic classification tests.
