dMAT vs TestAS: What Changed and Who Must Take It
For years, "TestAS" was the answer whenever Indian applicants asked which aptitude test Germany wanted. That answer has changed. The dMAT — the digital Master Test, run by g.a.s.t. (the same organisation behind TestAS and TestDaF) — has replaced TestAS in the APS process for Indian students. If your seniors prepared for TestAS, their advice, books and question styles no longer match what you will face. Here is what actually changed.
What happened to TestAS?
TestAS was a scholastic aptitude test developed by g.a.s.t. with ITB Consulting, built around a Core Test plus subject-specific modules, and offered on fixed test dates through a network of centres. It served for well over a decade as the standard aptitude check for international applicants to German universities.
g.a.s.t. has now retired that format for the Indian APS route and moved to the dMAT: a fully digital assessment with new task types, taken as part of the APS certification process. The organisation behind the test is the same; the exam in front of you is not.
The dMAT format
The dMAT is taken on a computer and is built around two parts:
The Core: three subtests, 25 minutes each
- Figure sequences. You see a series of figures changing by hidden rules — rotations, reflections, elements added or removed — and pick what comes next. This tests pattern recognition under time pressure.
- Mathematical equations. Numerical reasoning without a calculator: completing and balancing equations, working with operators and quantities quickly and accurately.
- Latin squares. Grid puzzles where each symbol must appear exactly once per row and column. You deduce missing entries from the constraints — pure logic, learnable with practice.
The General Academic Module
Beyond the Core, the dMAT includes a General Academic Module that assesses broader academic reasoning. Together with the Core subtests, a full sitting runs about 165 minutes.
Two rules shape how you should play it: no calculators or notes are allowed, and guessing is not penalised — a blank answer can only cost you, never help you.
dMAT vs TestAS at a glance
- Delivery: the dMAT is digital end to end; TestAS was long associated with paper-based sittings at test centres.
- Task types: the dMAT's Core — figure sequences, mathematical equations, Latin squares — is a different set of tasks from the TestAS Core Test. TestAS preparation material does not map onto them.
- Subject modules: TestAS offered discipline-specific modules; the dMAT pairs its Core with a General Academic Module instead.
- Where it sits: for Indian applicants the dMAT is embedded in the APS stage — you meet it while getting your APS certificate, before visa and (in most cases) before final admissions decisions.
What stays the same
It is worth naming what has not changed, because it shapes how you should feel about the switch. The test is still run by g.a.s.t., the established provider behind TestDaF and TestAS, so the administration and standards are familiar territory for German institutions. It is still an aptitude test, not a subject exam: it measures reasoning, not your board syllabus, so there is no textbook to revise and no advantage for one stream over another beyond the skills themselves. And it is still a test where preparation visibly pays off — the task families are learnable, and the difference between a cold first attempt and a practised sitting is large. The exam changed; the way you beat it did not.

If you are an Indian applicant going through the standard APS procedure — which covers the vast majority of bachelor's and master's aspirants — the dMAT is part of your path. Exemptions from APS itself (certain doctoral candidates and scholarship holders, for example) are defined by APS India, and where APS is not required, the dMAT question may not arise at all.

Do old TestAS scores still count?
This is the question every batch with seniors asks, and it is exactly the kind of transition detail that gets decided — and revised — by the authorities, not by prep companies. If you hold a TestAS score from an earlier attempt, do not assume it transfers: contact APS India or check the official announcements on aps-india.de and d-mat.de before you plan around it. Individual universities may also have their own views on aptitude-test evidence for admission purposes, separate from the APS requirement.
Rule of thumb for a transition year: plan as if you will take the dMAT, and treat any recognition of an old TestAS score as a pleasant surprise confirmed in writing — not as your default plan.
How preparation changes
- Practise on a screen, against a clock. A digital exam rewards familiarity with digital pacing. Solving puzzles on paper at leisure trains the wrong reflexes.
- Learn the three Core task families cold. Figure sequences, equations and Latin squares are all learnable — scores rise sharply once you have seen a few hundred examples of each and know the recurring rule patterns.
- Do full-length sittings. 165 minutes of sustained concentration is its own skill. At least a few of your practice sessions should be complete, uninterrupted papers.
- Answer everything. With no penalty for guessing, an unfinished section is pure lost marks. Pacing practice is what prevents that.
