Becker – The IIA CIA® Exam Review (#1)
-
Official IIA-Approved Content: Becker is the only CIA review course officially partnered with The Institute of Internal Auditors (IIA), the organization that writes the exam. That means you’re getting the most accurate and exam-aligned content on the market — straight from the source.
-
Adapt2U™ Smart Technology: This adaptive learning engine personalizes your quizzes and review sessions based on your performance, helping you focus on the areas where you need the most improvement. It’s a great way to study smarter, not harder.
-
Generous Course Access: With 24 months of access, Becker gives you double the time most courses offer. This is perfect for busy professionals who want flexibility and aren’t cramming their studies into a short window.
-
Full-Length Mock Exams: Each part of the CIA exam comes with two full-length simulated exams. These are designed to mirror the real test in both content and format — ideal for building confidence before exam day.
Bottom Line: Becker’s partnership with the IIA alone makes it a standout, but that’s just the beginning. Its smart tech, updated curriculum, and upcoming multimedia features make this the most exam-ready prep course on the market. If you want confidence that your materials are accurate, current, and built to help you pass, Becker is the top pick.
Gleim CIA Review Course (#2)
-
One-on-One Counseling: A fantastic addition to Gleim’s CIA exam prep courses is their personal counselors. Each student gains access to their own counselor, who is there to answer any questions. With this one-on-one problem solver, you’ll find the learning experience easier than ever. Furthermore, your counselor will even make you a study plan and assist with any problems that arise during the course. All counselors can be contacted by both phone and email.
-
Practice Questions: Included with Gleim’s CIA course materials are thousands of multiple-choice test questions. By creating your own pool of these questions, you can actually design your own practice tests. This will allow you to cut out problems you don’t struggle with and instead focus on what you need most. Consequently, you’ll be able to make the study process extremely efficient.
-
Multi-Language Support: Gleim’s prep course is not exclusive to English speakers. It’s also available in Spanish for the convenience of anyone planning on taking their exams in that language. Multilingual courses are extremely rare in my experience; if this is something you’re interested in, you likely won’t find it elsewhere!
-
Final Review: Once you’ve reached the final weeks of studying, you’ll gain access to a cumulative final exam review. Due to Gleim’s eye for quality, it’s been designed to mimic the actual CIA exam as much as possible. Hence, if you take it before the real thing, you’ll gain an understanding of the test environment and test-taking experience. Thanks to this final review, the test-taking process will be easier than ever!
-
Overly Detailed Content: Some users of Gleim’s CIA materials have pointed out that the books cover more topics than necessary for the exam. Roughly 20% of the questions derived from these details reportedly don’t appear on the actual exam, potentially leading to extra, unnecessary study time.
Bottom Line: Gleim’s got your back with a personal counselor for all your questions and a customized study plan. Their practice tests let you focus on what you need, and they’ve even got a version for Spanish speakers. Plus, their final review feels just like the real CIA exam, so you know what to expect on the big day. It’s like having a study buddy who’s been through it all before.

Powers Resources CIA (PRC) Review (#4)
-
Additional Materials: In addition to the aforementioned practice questions, Power Resources includes flashcards and textbooks. Flashcards can be organized based on study priority. On top of that, each flashcard comes with extra space to take notes. Updates are also included at no extra charge.
-
Mock Exams: Upon completion of each CIA study section, you have the option to take two mock exams. Each exam is designed to mimic the true CIA exam as closely as possible so as to simulate the testing environment. Taking these tests makes your final review that much more effective. Even though other services offer similar tests, the quality of PRC’s tests shines above the rest.
-
Video Content: Much like Surgent, Power Resources’ focus does not lie in video content. Instead of audio or video lectures, students are expected to learn via their self-study materials. However, thanks to this focus, their study guides and practice questions are top-notch. If video isn’t that important to you, keep PRC in mind.
-
Limited Interactivity: The PRC CIA review offers a solid foundation for CIA exam preparation, but its platform may lack the interactive features and adaptive learning technologies that some competitors provide. This could mean a more static study experience for users who are accustomed to dynamic, tech-driven learning environments.
-
Lack of Brand Recognition: PRC CIA Review is not as widely recognized or established as some other CIA exam prep providers. This might raise concerns regarding the quality and reliability of their content, especially for candidates looking for a well-known and trusted source for exam preparation.
Bottom Line: While PRC’s mock exams stand out for their quality and closely mimic the actual CIA exam, there are notable concerns to consider. The lack of brand recognition might raise questions about content reliability. Additionally, with limited course variety, students seeking diverse study aids might feel restricted.
