Three out of three. I passed all three parts on my first try, and this system helped me do it. Although the CIA Learning System does not have the thousands and thousands of questions other courses proclaim to have, it provided an EFFICIENT and EFFECTIVE way for me to learn what I needed to and then assess what I learned. It focused me on understanding concepts rather than memorizing rote information and regurgitating it. I found that I was well prepared for the unusual and unfamiliar questions when they presented themselves in the exam. Kudos to a nicely designed system that did what I was hoping it would do.
