I truly believe that I would not have passed all 3 parts of the CIA exam on my first attempt without the Gleim review system. I think the combination of the books, Gleim Instruct Video lectures, and audio lectures helped me to comprehend the material better than if I had to rely on any one of those methods on their own. However, the biggest advantage that Gleim offers is their Personal Counselors. My Personal Counselor was part coach, part counselor. He was always prompt to respond and offered valuable tips and encouragement to keep me going. If you’re willing to put in the work, Gleim will give you all of the tools you need to pass your CIA exam. I would highly recommend them.
