FreeFellow has 1,374 free, original CIA practice questions: 498 for Part 1, 433 for Part 2 and 443 for Part 3, weighted to the IIA's published section percentages. Each has a worked solution, and most have notes on why the wrong choices are wrong. They're written to the current syllabus, the one aligned with the 2024 Global Internal Audit Standards. Samples need no signup, and the full bank needs a free account (it isn't a trial).

You can go straight to them: Part 1 (Internal Audit Fundamentals), Part 2 (Internal Audit Engagement), Part 3 (Internal Audit Function) and the CIA exam hub.

What good CIA practice looks like

CIA stems are short, most ask for the single best answer ("most appropriate", "best describes"), and the wrong choices are rarely false statements. They're reasonable-sounding actions that give a responsibility to the wrong party: management's job presented as the auditor's, the board's decision offered as the chief audit executive's, an objectivity problem presented as good practice.

So when you miss one, you need to know whose job the wrong choice described, and a bare answer key won't tell you. That's why most FreeFellow CIA questions have notes on each choice. The IIA's own sample questions are worth doing too. It publishes a small set on its website with a rationale for every option, and they show this pattern clearly.

No legitimate prep source sells actual CIA exam questions. IIA exam content is confidential and candidates sign a nondisclosure agreement at the test center, so anyone offering real questions is selling something you don't want to be associated with. Everything on FreeFellow is original and written to the published syllabus.

The paid alternatives

Gleim is the established CIA prep leader, with the largest test bank in the category. Its full three-part review courses cost $1,099 to $1,249, from Traditional to Premium (August 2026 price record), with cheaper bank-only options, and it's a reasonable buy if you want video lectures, a course calendar and access support. UWorld and Becker also sell CIA prep, so compare their current package scope, price and access terms. The IIA sells its own learning system too, comprehensive and priced to match, and you don't need it to pass.

If you want a full guided course, the paid options are worth it. If what you need is practice with real explanations, start with the free bank, which is plenty to see where you stand on each part before you spend anything. The exam already costs about $990 in member fees ($120 application, $310 for Part 1, $280 each for Parts 2 and 3), and the credential ROI map puts that next to the CPA, the CMA and the rest of the field.

What else is free

Every CIA learning objective has a free written lesson, 62 in all, and each part has a glossary. Timed full-length mock exams (two per part, at the real 125- and 100-question lengths), flashcards and analytics are in the paid Fellow tier. The full banks for the other finance credentials FreeFellow covers (CPA, CFA, CMA, EA, FRM, actuarial and more) are free at freefellow.org/free, with a worked solution on every question.
