Gleim was a great choice to help with my CIA exam preparation. I really liked having multiple learning methods available including the books which I used to learn the concepts and online practice tests which were helpful in learning how to apply them to different scenarios. It also helped to be able to see explanations for why an answer was right or wrong at the end of a practice test. The flexibility of the system and feedback to pinpoint areas I needed to work on really helped balance the demands of getting up to speed in a new job while also preparing for the exam.
