Why every answer in our apps quotes the law

Most licensing-exam prep is copied. One provider's test becomes another's, the wording drifts, the law changes underneath, and nobody can say where any particular answer came from. The person who pays for that is the candidate who walks into the exam with an answer that was correct three reforms ago.

We took a different starting point, and it is a simple one: a question that cannot point at its source does not ship.

What that means in practice

Every question in our apps stores four things alongside it: the document it comes from, the exact section or article, the date of the version we read, and a literal fragment of the text. Not a paraphrase — the words themselves. In the app, that fragment sits under the explanation, so you can see the sentence that makes the right answer right.

A mechanical check runs over the whole bank before any release and verifies that each stored fragment exists, character for character, inside the cited document. If a quote drifts by a word, the build fails. That check is the reason the rule survives contact with deadlines: it is not a good intention, it is a gate.

Why the marking formula matters as much as the content

A mock exam has one job: to tell you whether you would pass today. It can only do that if it marks the way the real paper marks.

Take the Spanish security guard exam. The rules mark it with [A − E/(n−1)] × 10/P, and with three options per question that means each wrong answer costs half a correct one. Estimate that penalty as "about a third" instead — a very natural-looking approximation — and the pass threshold moves from 67 correct answers to 63. Four whole levels where your app says pass and the exam says fail. Nobody notices, because the app never gets to be wrong out loud.

Or the rural guard exam, where wrong answers subtract nothing at all. An app that penalises errors there teaches exactly the wrong habit: it trains you to leave questions blank in a paper where a blank is a wasted point and a guess is free.

So we read the marking rule from the source too, and the mock implements it as written — penalty, scale, time limit, number of options and the treatment of unanswered questions.

Where the numbers come from

The exam facts we publish — how many questions, how long, what the pass mark is — are quoted from the resolution or regulation that fixes them, and we link it. When a source does not say something, we say that instead of filling the gap. AESA does not publish how it distributes questions across the nine A1/A3 subjects, so we do not claim to know: we say it is unpublished and weight the subjects evenly.

That distinction matters more than it looks. "The exam has 40 questions" is a fact with an article number behind it. "The exam has 8 questions on meteorology" is a guess wearing the same clothes.

What we will not do

• We do not publish or copy official question banks. For the exams we cover, no such bank is publicly available, and anything advertised as one cannot prove it.
• We do not ask for an account, an email address or a sign-up to let you study.
• We do not run analytics, ads or tracking, and your progress never leaves your phone.
• We do not promise you will pass. We can tell you the mark you would get today, calculated the way the board will calculate it. The rest is yours.

Where to look next

Each app page lists the exam's format with the source that fixes it, and each guide walks through one exam in detail. If you find a question you believe is wrong, the fastest way to get it fixed is to tell us which rule you think says otherwise — because every question already knows which rule it came from, checking takes minutes.
