CLEP Examination Preparation
CLEP's website sells the test program's official master study guide book, as well as individual exam study guides that may be downloaded for a fee. The guide will give you a bare bones description of the exam and will list the knowledge and skills required, as well as sample test questions. However, to study the specific content of the test it is strongly suggested you get a textbook in the subject area.
Some students have found it helpful to study from the InstantCert Academy website. Please note there is a fee for this site.
