CCA-F Practice Exams Compared

Sorted alphabetically by provider name - this is not a ranking. "Best" depends on what you're optimizing for, and the breakdown below sorts by that instead.

Every fact above came from fetching each provider's own page directly on 2026-08-04, not from a database or a competitor's marketing copy (first-hand: CertSafari, TutorialsDojo, explainx, one GitHub repo). Two things went wrong during that process worth naming, because they're the whole reason this page has a verification section at all: an earlier search-result summary for explainx said "$5 lifetime" - the price on explainx's own page, fetched directly, is $10. And certificationpractice.com blocked three separate automated requests (HTTP 429) across two tools and two different user agents, so its price, question count, and scoring mechanism are marked unconfirmed above rather than guessed. Two more free options exist in this space that we did not deep-verify for this table - claudecertifications.com and claudecertificationguide.com - named here rather than left as a vague "others exist."

There's a real difference between the two kinds of "free" on this page, worth naming because it's easy to miss when you're scanning quickly. Zero-friction free means the whole thing, no account, no card, ever - that's CAC's sample and diagnostic, CertSafari, and the GitHub repo. The free sampler means a taste before the paywall - TutorialsDojo's 20 questions, explainx's browse-only access - which is a completely legitimate way to sell a product, just not the same thing as "free" in the first sense. If what you actually want is unlimited free practice, only the first group delivers that; the second group is closer to a demo.

Match the option to what you're optimizing for, not to whichever one you found first.

• Want the most raw question volume for free? CertSafari's 614 questions is the largest verified free bank on this page.
• Want a scored result that mirrors the real exam's domain weighting? CAC's mock is the only option we could confirm scores to the real 1000-point scale with the real 720 pass mark, stratified to the official domain weights (certificationpractice.com's mechanism is unconfirmed), though it requires a paid plan - or explainx's paid mocks, which are also domain-organized.
• Want to practice without leaving your terminal? The GitHub Claude Code skill is the only reviewed option built for that.
• Want exam-simulation features - timers, flashcards, section drills - and don't mind paying? TutorialsDojo ($14.99/year) or explainx ($10 lifetime) both add those on top of a free option's raw questions.
• Want the biggest paid bank with an exact published count? explainx's 540 questions across 8 mock tests is the largest paid figure checked here (TutorialsDojo doesn't publish its full total; Udemy varies by course).

None of that requires paying anything to start. If you want to see where you'd actually land before deciding whether to go deeper, CAC's free diagnostic needs no account for the sample or the 10-question diagnostic, and takes about 10 minutes.
