The CLEP, or College Level Examination Program, is a battery of tests given as a set of college entrance exams to adults returning to the classroom after an absence of several years--perhaps after working at a full-time job or raising a family. This updated manual presents three full-length sample examinations in each of the test areas covered in this book and provides answer keys, a scoring chart, and answer explanations for all exams. It also presents subject reviews in five CLEP test topics with additional practice and review questions. Test topics covered are the English Composition Exam, the Humanities Exam, the College Mathematics Exam, the Natural Sciences Exam, and the Social Sciences--History Exam.
