How we build and check our questions

01Official public sources only

We only build apps where the underlying material is openly reusable: public-domain law and regulations, or official handbooks released under an open licence such as Creative Commons (CC BY) or a government open-data licence. Each app's landing page names its exact sources, for example the enacted statute, the regulation, or the official study booklet. We write original questions from those facts. Facts are not copyrightable, and we never copy an official exam's own questions.

02Every question cites a source passage

When the AI generates a question, it must point to the specific passage of the source material that establishes the correct answer. A question that cannot be tied back to the source is not kept. This citation is the anchor for the verification step that follows, and it is why our explanations can tell you where a rule comes from, not just what it is.

03Cross-model verification

This is the core of the process. The question and answer are written by one AI model. They are then checked by a second, independent model from a different family, which reads the cited passage and decides whether it genuinely supports the marked answer, returning a confidence score. Using a different model for verification matters: a model is far less likely to wave through another model's mistake than to repeat its own. Where the two models agree with high confidence, the question passes. Where they disagree, or the verifier is unsure, the question is set aside.

04Structural and duplicate checks

Alongside the answer check, an automated gate validates the mechanics of every item: that it has the right number of options, exactly one correct answer, a working explanation and a valid category, and that it is not a near-duplicate of another question. Items that fail these structural checks are rejected before a human ever sees them.

05Human review of disagreements

A human does not re-grade thousands of questions by hand; that would be slower and, with fatigue, less reliable than the machine checks. Instead, human attention goes exactly where it adds the most value: the questions the two models disagreed on and the items the verifier flagged as ambiguous. Each of those is reviewed against the source and either corrected, rewritten or dropped.

06What we do not claim

We are deliberate about the limits. Our apps are independent and are not affiliated with or endorsed by any government, licensing board or testing provider. We do not guarantee a pass, and we do not claim our content is exhaustive or error-free. Where an exam authority publishes an official pass mark, time limit or question count, we use it and cite it; where it does not, we say so and clearly label our own practice format as unofficial rather than presenting a guess as fact.

07Keeping content current

Laws and handbooks change. Each app records the sources it was built from and the date its content was last reviewed, shown on the app's page. When a source is updated, we revise the affected questions and bump that date. We would rather show you exactly what a set of questions is based on, and when it was last checked, than ask you to take our word for it.

08Check us yourself

Every app page lists its official sources and a set of sample questions you can read for free before buying, and each exam also has free practice questions on the web. The honest test of any prep tool is to compare a handful of its questions against the current official handbook or statute. We build the apps so that comparison is easy, and we link the sources so you can do it.

09Common questions

Are RiverMap Learning questions written by AI?

Yes, and we say so plainly. We use modern AI to turn official public study materials into practice questions, flashcards and explanations. What makes the result trustworthy is the checking: every question is generated against a specific source passage and then verified by a second, independent AI model from a different family before it ships, with a human reviewing any disagreement.

How do you know the answers are correct?

Each question is written to cite the exact passage of the official handbook, statute or regulation it comes from. A second AI model, different from the one that wrote the question, then reads that passage and confirms it actually supports the marked answer, returning a confidence score. Questions the two models disagree on, or that the verifier flags as ambiguous, are held back for a human to review. Only questions that clear this gate go into the app.

Is this affiliated with the government or the exam board?

No. RiverMap Learning apps are independent study tools. They are not affiliated with, endorsed by, or connected to any government body, licensing authority or examination provider. We build from publicly available official materials (public-domain law, or handbooks released under open licences such as CC BY or government open-data licences) and write original questions; facts are not copyrightable, and we never copy official exam questions.

Does passing the practice mean I will pass the real exam?

No study tool can promise that. Our mock exams mirror the official format and pass mark where the authority publishes one, and we clearly label any practice length or pass mark that is our own rehearsal format rather than an official figure. Use RiverMap alongside the official handbook, not instead of it.
