2. Gleim CIA Review Course

Since the groovy mid-70s, Gleim has been the go-to for those who crave depth in their study materials. Their reputation? Think of them as the CIA prep maestros with textbooks so comprehensive, they leave no stone unturned.

Dive into Gleim CIA Review, and you’re greeted with a whopping 3,000+ practice questions. And if you’re the kind who crams (no judgment here!), their final review is a lifesaver, spotlighting crucial topics just before D-day.

But here’s where Gleim truly shines: the personal counselor. Imagine having a CIA prep Yoda by your side, guiding, nudging, and yes, occasionally giving you that much-needed kick to dive back into the books. With Gleim, you’re not just studying; you’re embarking on a journey with a mentor.

However, every rose has its thorn 🌹🥀. Some users have mentioned that Gleim’s course, while incredibly detailed, can feel a tad overwhelming, especially for those who prefer a more concise review. But if depth is what you seek, Gleim’s your beacon!

Recently updated for 2025: Including an extra CPA final review exam for more practice and improved course outlines.

3. Wiley CIA Review

Once a titan in the CIA review world, Wiley CIA’s new chapter under UWorld brings with it unanswered questions and potential changes. Until the dust settles and the direction becomes clear, we’re hesitant to give them our stamp of approval.

Wiley CIA Review has long stood as a pillar for students, with its self-study materials and progress tracking acting as a guiding light through the intricate maze of CIA content. Those video lectures? Think of them as knowledge snacks, delivering 34 hours of concise, clear concepts straight to your brain.

The mock exams are your proving ground. After immersing yourself in the course, these exams challenge you to apply all you’ve learned in an environment that mirrors the real CIA exam. It’s like a final rehearsal before the main event. And the progress-tracking? It’s akin to having a fitness tracker for your brain, ensuring you’re always strengthening those weaker knowledge areas.

However, every rose has its thorn. Some students have pointed out that while the course is comprehensive, it can sometimes feel a tad overwhelming, making it a bit of a trek to navigate. Additionally, the course’s adaptive learning, though groundbreaking, might not click with everyone, especially those who lean towards a more straightforward study approach.

But here’s the twist: Wiley CIA Review has been acquired by UWorld. While acquisitions can usher in fresh perspectives and enhancements, they also introduce a degree of unpredictability. The future trajectory of the course under UWorld’s stewardship remains somewhat ambiguous. Given this backdrop, we find ourselves in a position where we can’t fully endorse Wiley CIA Review for now. The path ahead is foggy, and we’re all about charting a course through clear skies.


4. PRC CIA Review Course

offers a solid review course for budding internal auditors. However, it doesn’t quite hit the high notes like Surgent or Gleim. The absence of video lectures and adaptive learning technology is a noticeable gap. If those are your must-haves for acing the CIA exam, you might want to look elsewhere.

That said, PRC isn’t without its merits. Boasting over 3,500 practice questions and two mock exams that mirror the real CIA test, it offers tangible value. Plus, its affordability and modular packages (covering specific parts of the three-part exam) are a boon for budget-conscious learners.

But here’s the rub: PRC might be best suited for those who’ve already taken a swing at the CIA exam and are looking to hone in on specific areas. If that’s you, consider diving into one of their single-part packages, leveraging their question bank and mock exams to sharpen your skills before your next attempt.


5. IIA CIA Learning System

The Institute of Internal Auditors (IIA) is the brains behind the CIA exam, so it’s tempting to lean into their study materials. While they might not top the charts, there’s some merit in using resources straight from the horse’s mouth.

A standout feature of IIA’s CIA Learning System is its emphasis on microlearning. They’ve neatly packaged lessons into digestible chunks, making it easier for those juggling a busy schedule to stay on track.

However, there are a few hitches. For starters, it’s pricier than offerings like Surgent’s, and the absence of adaptive learning tech is a letdown. Plus, if you’re on the hunt for a plethora of CIA exam practice questions, Gleim might be more up your alley.
