Why Kollego exists

TestAS and the Studienkolleg Aufnahmeprüfung are the gatekeeper exams standing between thousands of international students and a MINT degree in Germany — and the prep material for them is still mostly static PDFs and scanned past papers.

Kollego is built on the idea that the material itself should be interactive: an answer you manipulate on screen, not one you read about. Every practice item is generated by a real parametric engine, not pulled from a fixed question bank — so you never run out of fresh practice, and never memorize an answer instead of learning the underlying skill.

The progress estimate you see is shown as a labelled practice range, not a single confident number — it's an honest estimate, not an official prediction. We'd rather undersell certainty than oversell it.

Pricing is purchasing-power-adjusted, because a fair price in Munich isn't a fair price in Lagos or Lima — and the applicants this product is built for are concentrated in exactly the markets where a flat euro price doesn't make sense.

Kollego is an independent product, not affiliated with g.a.s.t., TestDaF-Institut, or any Studienkolleg.
