This electronic version of of the study guide allows the individual student to proceed through the questions in any order, find out immediately whether his or her answer is right or wrong, and be referred to the print manual for correct answers as necessary.

Most questions are in the same multiple-choice format that is used on civil service and certification examinations. The program also tracks the results of each session as a record of progress.

Each time a student goes through the program, the questions are rearranged randomly to prevent answering correctly through rote memorization.
