How we write and check our questions

AI models write or revise StudyWren's questions, explanations and guides from official sources. A separate AI agent then checks each question and guide against those sources. Automated checks, audits of random samples and a record of every change back that up.

Who writes and checks them

AI models write or revise the questions and check them, working from the text of the regulations, handbooks and laws. Each question is checked by a separate AI agent that didn't write it and reads the sources itself. No licensed flight instructor or insurance agent reviews them.

So you can check our work, aviation explanations cite their FAA source, and many insurance explanations name the section of law they rest on.

Where the questions come from

• Private Pilot: current 14 CFR, the Aeronautical Information Manual, the FAA's pilot handbooks, the Private Pilot ACS (FAA-S-ACS-6C) and the testing supplement (FAA-CT-8080-2H).
• Part 107: 14 CFR Parts 107, 89 and 48, AC 107-2A, the Remote Pilot ACS (FAA-S-ACS-10B) and the FAA's Remote Pilot study guide.
• Insurance: each state's laws and regulations, standard policy forms, and federal law where it governs.

ISO's standard policy forms aren't public, so some answers about them rest on copies posted online or on secondary sources. California's official code site blocked automated reads, so its statutes were read from an unofficial copy of the codes.

Our Private Pilot and Part 107 questions are original, not the FAA's live test questions, which it doesn't publish. The Part 107 course also includes the FAA's 46 published sample questions, three of them updated for rule changes, with our explanations.

In a released course, every question has one correct answer, and each wrong option must be wrong under current rules. No explanation names an option by its letter, so the options can be shuffled. Each wrong option gets its own "Why not?" explanation.

How each question is checked

• Private Pilot: a separate verifier agent checked every question's answer, wrong options, explanation and any calculation against the source text.
• Part 107: a verifier on a different AI model checked every question against the sources. A model from another company then answered every text question without seeing our answer, and every question it flagged was settled from the sources.
• Insurance: every question in a released course was rechecked against current state law in October 2026. Each one was in a batch with a writer and an independent verifier.

The Private Pilot and Part 107 "Why not?" explanations were fact-checked against the sources in random samples, not one by one.

Scripts check the banks too: the number of options, duplicate options, explanations that name an option's letter, and wrong options without a "Why not?". They also flag a correct answer that is too often the longest option, a common giveaway.

Audits of random samples

To measure what the checks missed, fresh AI agents that took no part in writing or checking recheck a random sample of finished questions. An error is a wrong answer, a second option that is also right, or an explanation that teaches something false. Each course's latest audit, all in October 2026, found these errors or ambiguous questions:

The Private Pilot sample is two audits of 140. Part 107's audit counts a wrong fact in an explanation as minor, not as an error. It found 3 minor problems in explanations or "Why not?" text, all fixed.

The first Texas audit, on October 21, 2026, found 9 errors or ambiguous questions in 140. That led to a second fact-check of 864 Texas questions, which fixed 281 errors, and the new audit above found none.

An insurance course is released only when its audit finds at most 3 errors or ambiguous questions in 140, all fixed. Early-access insurance courses haven't passed this yet. The app labels them "Early access", and this site doesn't show their questions.

Content versions and "Verified through"

Every released course has a content version, such as 2026.10.4: the year and month it was made, then a count. Any change you would see, from a corrected answer to a rewritten "Why not?", makes a new version. A check fails if the content changes without one.

"Verified through October 2026" is the month the course's sources were last checked, by the change check below or an audit. The apps show both under Settings → About, and each course's page here shows them too.

Keeping up with rule changes

One script checks our sources for changes. It runs by hand, not on a schedule: our routine is once a month and before every app release.

• Private Pilot: the AIM, the Private Pilot ACS, the FAA's handbooks, the regulations and the Federal Register.
• Insurance: the Texas and California insurance codes, their insurance rules and their insurance departments' notices.

Part 107's sources are checked by hand before a release, and Pennsylvania doesn't have an automated watch yet. When a source changes, a writer and an independent verifier recheck the questions it affects, and the fix ships as a new content version.

What changed

Every content version has an entry in What changed, in the apps under Settings → About. Each entry counts the questions corrected, added or retired, and says what changed in plain words. A question the newest version corrected says "Updated" in its details.

Guides, answers and free tools

Each guide, answer and free tool on this site is written from official sources only. The sources are the FAA, the eCFR, state insurance departments, state laws and regulations, and the testing vendors' own pages. A separate AI verifier then reopens every source, checks each claim and fixes the page.

Every fact links to its source, and "Last verified" is the day the verifier finished. We keep the writer's notes and the verifier's record of every statement checked. When we change a page, the changed facts are rechecked first.

Report a problem

Every explanation, in the apps and on this site, has a Report a problem link, and the report form covers anything else. We check each report against the official source, never on the report alone. A fix ships as a new content version with its What changed entry.

What this doesn't cover

• StudyWren isn't official guidance. Rules and fees change, so confirm anything important with the source.
• Practice doesn't replace an instructor's endorsement or any pre-licensing education your state requires.
• Early-access courses are still being verified, so some questions may be out of date or worded imperfectly.

StudyWren is an independent study tool and isn't affiliated with the FAA, any state insurance department or any testing vendor.
