Certified Information Systems Auditor (CISA) is an exam sponsored by the organization named ISACA. Passing this exam is one of the requirements for becoming a CISA. The exam is guiling. You need to answer 150 questions in four hours or less. The questions are not very long; so just over a minute a half per question should be quite sufficient—that is, if you can grasp the meaning of a question on the fly. The problem is not that you’ll have only a minute and a half to read a question. The problem is that a minute and a half is all you are going to get for coming up with the correct answer. Sounds easy?—Think again! ISACA doesn’t publish any information about the candidates’ success rates, but a rumor has it that only one half of the candidates pass the exam on the first attempt.
