When preparing for the three-part CIA certification I choose to rely on the GLEIM CIA Review System and was awarded with the “William S. Smith Certificate of Honor”. I am convinced that the skillfully composed set of teaching and training material offered by GLEIM contributed significantly to successfully passing all exams on the first attempt. The studying material offers highly structured and concise yet comprehensive and easily understandable information. It also contains helpful tips on how to prepare and sit for the exam. The study and practice exams, that are available online, served to simulate the actual exam experience very well and fostered acquaintance with the style of multiple-choice questioning. In addition, online exam preparation also allowed me to precisely identify and train the knowledge areas, where additional effort was either necessary or invested with the best results. All in all, I highly recommend GLEIM to anyone looking forward to preparing for and taking the CIA exams while working as an full-time auditor.
