Let’s face it. The CIA exam is extremely difficult compared to other exams you have taken. Because of the large volume and variety of topics, you must adjust to answering questions that require educated guessing.
Challenge yourself by starting your study of each unit with a multiple-choice quiz in test mode of your CD-Rom. When you are confronted with a question that you cannot answer, look at each answer choice individually and treat them like a true or false question. This will help you eliminate a few of the answers and differentiate the correct choice from the distractors.
