The College Level Examination Program (CLEP) enables students to demonstrate college-level achievement and earn college credit in various subject areas based on knowledge acquired through self-study, high school and adult courses, or through professional means. The CLEP Information Systems Passbook(R) prepares you by sharpening knowledge of the skills and concepts necessary to succeed on the upcoming exam and the college courses that follow. It provides hundreds of questions and answers in the areas that will likely be covered on your upcoming exam, including but not limited to: system hardware and software; computer programming; telecommunications; and more.
