TestAS Exam 2026: Complete Guide to the Digital & Paper-Based Test for Academic Studies
Everything you need before you register — exam structure, subtests, subject modules, dates, fees, and how to actually train for it — checked directly against the official TestAS website.
The TestAS (Test for Academic Studies) is a standardised aptitude test for international applicants who want to study at a German university. It is developed and administered by g.a.s.t. (Gesellschaft für Akademische Studienvorbereitung und Testentwicklung e. V.) — the same organisation behind TestDaF. TestAS does not test subject knowledge; it measures general cognitive aptitude such as logical thinking, working memory, numerical reasoning, and pattern analysis, plus (in the Subject Module) your ability to work with material from your intended field.
A good TestAS result can strengthen a university application or, at some institutions, is a required part of it. It also helps universities compare applicants whose school qualifications come from very different education systems.
Official source: All structural details below (timings, subtests, item counts) are taken directly from the official TestAS website: testas.de/en. Always confirm current dates and fees there before registering, since these can change.
Digital vs. Paper-Based: Two Formats, Same Skills
TestAS is offered in two formats. Both test the same underlying abilities and place the same demands on you, but the exact subtest composition, timing, and delivery method differ slightly. You choose one format when you register — check which format your target university's test centre offers before booking.
| Digital TestAS | Paper-Based TestAS | |
|---|---|---|
| Delivery | On computers at licensed test centres | Pen-and-paper at licensed test centres |
| Language | German or English, your choice | German or English, your choice |
| Core Module | 3 subtests × 25 min each (~90 min incl. instructions), 20 items per subtest | Same three subtests, paper answer sheets |
| Subject Module | 10–15 testlets, 4–8 questions each, 90 minutes total | Same format, paper-based |
The Core Module: Three Subtests
Every TestAS candidate takes the Core Module. It measures general and analytical thinking, working memory, arithmetic, and the ability to recognise and link visual patterns — through three subtests.
1. Figure Sequences
You are shown a series of images (matrices). Figures within the matrices change position, colour, and/or alignment from one matrix to the next according to a hidden rule. Your task is to work out the logic and continue the sequence correctly.
2. Mathematical Equations
You are given a system of equations built from unknowns represented by letters. Each letter has one value between 1 and 20 that satisfies every equation in the system simultaneously. Unlike the other two subtests, answers here are worked out rather than chosen from single-choice options.
3. Latin Squares
You see a 5×5 grid, partially filled with letters. Two rules apply:
- Each letter may appear only once in every row and every column.
- Only the letters A, B, C, D, and E are used in the grid.
You determine which letter belongs at a marked cell — sometimes you'll need to work out other cells mentally first before you can solve for the target one.
Answers in the digital format are given almost entirely as single-choice selections — the exception is Mathematical Equations, where you work out the numeric answer yourself. In the Core Module you get two short breaks at your desk, followed by a 30-minute break outside the room before the Subject Module.
The Subject Module: Six Elective Fields
After the Core Module, you take one Subject Module matching your intended field of study. Each testlet presents a topic through text, graphics, or tables, then asks questions testing whether you understood and can apply the concept — not whether you already know the subject.
| Module | Core Topics |
|---|---|
| Humanities, Cultural Studies & Social Sciences | Philosophy, history, linguistics, literary studies, political science, sociology, social science methods |
| Life Sciences | Biology, (bio)chemistry, physics, computer science, psychology, mathematics & statistics |
| Engineering | Mathematics & statistics, physics, chemistry, materials, technical mechanics, thermodynamics, electrical engineering, computer science, development & construction |
| Mathematics, Computer Science & Natural Sciences | Mathematics, computer science, chemistry, physics, earth sciences, scientific work |
| Economics | Business administration, economics, mathematics & statistics, law, information technology |
| Medicine | Anatomy, physiology, biology, (bio)chemistry, psychology & sociology for physicians, physics |
Technical vocabulary knowledge is not assumed anywhere — what's assessed is comprehension, application, and transfer, plus (for maths/science/economics/engineering fields) comfort reading diagrams and formulas.
Fees, Dates & Registration
Registration for TestAS is handled exclusively through the official participant portal. According to the official TestAS site, upcoming test dates include 24 October 2026, 26 November 2026, and 25 February 2027, with more added throughout the year. Registration periods typically open a few months ahead of each date, and fees vary by test centre and country, so always check the exact figures listed for your chosen centre.

In China, Vietnam, and India, TestAS is generally administered as part of the APS procedure — check the official page on TestAS in China, Vietnam and India for how this applies to you.
How to Actually Prepare
TestAS measures reasoning ability, not memorised facts, which means the classic "study the same question bank until you recognise it" approach has limited value. The figure sequences, equations, and Latin Square parameters are generated fresh for every candidate — so training pattern recognition, not pattern recall, is what actually transfers to exam day.
The official site itself publishes free preparation material — sample questions, task explanations, and instructional videos for each subtest — and this should always be your first stop. Beyond that, deliberate, timed practice across all three Core Module subtests (plus your Subject Module) is what builds real exam-day speed and accuracy.
Practice the Core Module logic types, free
I built TestAS Mastery, a browser-based practice suite that procedurally generates fresh Latin Squares, Figure Sequences, and Mathematical Equations questions — plus a timed exam simulator and progress dashboard — so you're always training recognition rather than recall.

Is TestAS pass or fail?
No. There's no minimum passing score. Results are reported as points, percentile ranks, and standard values, and each university decides how much weight to give them.
Can I take TestAS in English?
Yes — you choose German or English when registering (language level A2–B2 CEFR is expected). A few universities require a specific language, so confirm with them directly.
How many times can I retake it?
TestAS can be retaken; check the official FAQ page for any waiting-period rules that may apply to your test centre.
Where do I register?
Only through the official TestAS site and its participant portal — testas.de/en.
