It is comprised of three books: the Exploring World History Student Review, Exploring World History Quiz and Exam Book, and the Exploring World History Answer Key. The Exploring World History Student Review includes review questions (covering each lesson, selected readings from In Their Words, and each of the recommended works of literature), commentary on Bible readings, and literary analysis of the twelve titles suggested for students. The Quiz and Exam Book contains history quizzes for each unit, and six comprehensive exams in history, English, and Bible that each cover five chapters' worth of material. Pages are perforated and designed to be torn out and written upon by the student. The Answer Key contains answers to the review questions, quizzes, and exams, as well as to the answers posed in the literary analysis. Questions are reproduced with the answer in italics; page numbers where answers may be found in the text are provided. Answers are organized by unit and lesson. All books are non-reproducible, consumable resources.
