I prepared for all three CIA exam parts using The IIA’s CIA Learning System and passed them all on my first attempt. I studied in phases, starting with the reading materials that were so comprehensive that no other sources were needed. In the second phase, I completed practice questions. This is the best part of CIA Learning System, providing reinforcement and feedback. In the third and last phase, I used the practice exam to evaluate my preparation level and focus on topics to improve. The IIA’s CIA Learning System is the key to success on the CIA exams and I would highly recommend it to CIA candidates.”
