How Kollego works

From first diagnostic to exam day

Pay once for the months you need. Nothing renews, and your progress stays when it ends.

  1. 01

    Find out where you stand

    A short diagnostic across your exam's sections, with a projected score range on the official scale and a map of your weak skills.

  2. 02

    Study every day toward your date

    Set your exam date and daily minutes. Each day's session targets your weakest skills and shifts as they improve.

  3. 03

    Practise, don't memorise

    Interactive lessons, adaptive practice with freshly generated questions, hints and worked solutions, and full-length timed mocks.

Active practice

Solve it yourself, don't watch someone else solve it

Watching a worked example feels like learning, but the exam asks you to produce the answer, alone and against the clock. Kollego is built around doing: you solve, get checked step by step, and the next question adapts to what you got wrong.

Questions

Before you start

Is Kollego affiliated with TestAS or a Studienkolleg?+

No. Kollego is an independent prep product. TestAS is run by g.a.s.t./TestDaF-Institut; Studienkolleg entrance exams are run by individual Studienkollegs or state education authorities. We prepare you for these exams, we don't administer them.

Do I need TestAS or a Studienkolleg?+

It mostly depends on whether your existing school qualification is already recognized as equivalent to a German Abitur. If yes, you typically need TestAS for competitive MINT programs. If not, you usually need a Studienkolleg year first, ending in that Kolleg's Aufnahmeprüfung. Try our 2-question quiz for a quick pointer.

What's the difference between Digital and Paper TestAS?+

Digital TestAS is the current, primary format: computer-based, with a 3-subtest Core Module (20 items/25 min each) and a testlet-based Subject Module. Paper-based TestAS still runs a few times a year (e.g. April and October) but is being phased out, and has a differently structured 4-subtest Core Test.

How is the free plan different from Prep+?+

Free gives you one diagnostic per track, the first unit of lessons, 15 practice items a day and one mock exam in total. That's enough to genuinely evaluate the product. Prep+ removes every cap: unlimited practice, all lessons, unlimited mocks, diagnostic retakes and every track at once.
