The IIA’s CIA Learning System has proven to be an effective learning tool to prepare for and pass the CIA examinations. The texts are well written and concise. The online quizzes and practice examinations are a great way to evaluate your progress and provide reinforcement to the material in the text. I used the text and online quizzes/practice examinations as my sole means of preparing for the examinations and I am pleased with the results. I highly recommend the IIA learning system for anyone who wants to take the CIA examinations.
