A test bank is a collection of exam questions with answers, oftentimes in multiple-choice format, that professors can use to create exams. It is a resource that instructors can turn to when they are looking for new or different material to include on an exam. The questions in a test bank usually cover the main topics that will be covered in the course, and they can be a helpful study aid for students as they prepare for exams.
The sixth edition of “Anatomy and Physiology” by Elaine N. Marieb is a popular textbook used in many college-level anatomy and physiology courses. This edition of the textbook includes a test bank with over 1,000 questions. The questions cover all of the major topics that are covered in the textbook, making it a valuable resource for both instructors and students.
