Having used Gleim in preparation for the CPA exams, I chose to use them again to prepare for the CIA exams. The combination of the online test bank of practice questions, books for all three parts and audio/video explanations were helpful in learning how to apply the knowledge to different areas of the exams. The practice exams provided a realistic interface that emulated the actual exam. Explanations for why each response was right or wrong on the practice questions were helpful to increasing my understanding of the content. The study planner was useful in making sure that I was staying on track with my studies. I would recommend Gleim to prepare for the CIA exams.
