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 official section percentages, each with a worked solution and a note explaining the wrong answer choices. They are written to the current syllabus (the one aligned with the 2024 Global Internal Audit Standards), they require no signup, and they are not a trial.
Go straight to them: Part 1 (Internal Audit Fundamentals), Part 2 (Internal Audit Engagement), Part 3 (Internal Audit Function), plus the CIA exam hub.
What good CIA practice looks like
CIA questions have a distinctive construct. Stems are short, most items ask for the single best answer ("most appropriate", "best describes"), and the wrong choices are rarely false statements. They are defensible-sounding actions that misassign a responsibility: management's job dressed as the auditor's, the board's decision offered as the chief audit executive's, an objectivity impairment presented as good practice.
That has a direct implication for how you practice. A bank that only tells you the correct answer teaches you facts. A bank that explains why each wrong choice is wrong teaches you the role map, and the role map is what the exam tests. That is why every FreeFellow question carries per-choice notes, and why the official IIA sample questions are worth working too: the IIA publishes a small set on its website, with rationales on every option, and they show exactly this pattern.
One note that applies to every provider: no legitimate prep source sells actual CIA exam questions. IIA exam content is confidential, and candidates sign a nondisclosure agreement at the test center. Anyone claiming to offer real exam questions is selling something you do not want to be associated with. Everything on FreeFellow is original, written to the publicly published syllabus.
The paid alternatives
Gleim is the established CIA prep leader, with the largest test bank in the category and full review courses. Its full three-part review courses list at $1,099 to $1,249 (2026 list prices, Traditional to Premium), with cheaper bank-only options, and it is a reasonable buy if you want video lectures, a structured course calendar, and access support.
UWorld and Becker both entered CIA prep with strong explanation quality, typically at higher price points than Gleim's bank-only options.
The IIA's own learning system is the official course line; it is comprehensive and priced accordingly, and buying it is in no way required to pass.
Whether to pay comes down to what your gap is. If you need a full guided course, the paid options earn their price. If your gap is practice volume with real explanations, work the free material first: the entire three-part bank with per-choice notes is free here, which is more than enough to diagnose where you stand on each part before you spend anything. The exam itself already costs about $990 in member fees ($120 application, $310 Part 1, $280 each for Parts 2 and 3), so a dollar not spent on prep is a dollar off the real total, which the credential ROI map puts in context against the CPA, CMA, and the rest of the field.
What else is free, and what is not
Beyond the question bank, 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 part of the paid Fellow tier. The complete banks for the other finance credentials FreeFellow covers (CPA, CFA, CMA, EA, FRM, actuarial, and more) are free at freefellow.org/free, with the same worked-solution treatment on every question.
