Information Systems and Computer Applications - 75
Used this site and the Peterson's free tests to prepare a little bit before taking. As mentioned, the exam is dated a little bit, and my version of the exam didn't include as many "easy" questions about hardware and software applications as the practice material. But, all in all, it is definitely passable if you have some advanced computing knowledge.
