A small studio that does one thing obsessively

We build apps for passing official exams. The obsession is traceability: if a question claims something, it has to be able to point at the exact article and paragraph it came from.

Why it exists

Licensing exam prep is sold as tests copied from one another, with no sources and often out of date. The cost is not paid by whoever sells them: it is paid by the person who walks into the exam with an answer that was correct three reforms ago. Our answer to that is not more content — it is content with provenance.

How a question is made

We find the rule in force and read the part that governs: the resolution in the state gazette, the European regulation, the authority’s guide. The exam format, the time limit, the number of options and the pass rule all come from there.
The question is written with its explanation and, on top of that, the reason each wrong option is wrong. Knowing why B is wrong teaches more than knowing that A is right.
The literal quote from the source is stored. An automated check confirms that the fragment exists word for word in the cited document; if it does not match, the question cannot ship.
The mock is calibrated with the real exam’s formula, penalty included. A simulator softer than the real paper lies in the most expensive direction.
