I utilized the Gleim CIA study program as suggested in the study guide and was able to pass all three parts within six months. It was very beneficial to have on-line study material and practice questions. With a busy work schedule, I needed to get the most of my study time. Having access to the study material on my iPad when away from home enhanced my study time. Being able to customize test exams and identify areas of follow-up allowed me to concentrate on the needed areas of review. The amount of material required to study can be imposing. But, stick to the Gleim study outline and schedule and you will be very happy when you see your exam grade. There is no doubt in my mind that the Gleim study methods helped me to score exceptionally well on the CIA exam.
