What the dMAT Actually Tests

Almost everything written about the dMAT so far was written from the announcement. In July, g.a.s.t. published the official preparation material for the General Academic Module, and it answers the one question the announcements left open: what the test actually asks you to do. Three things in it should change how you prepare.

This page is about the test itself. If you are still checking whether it applies to you at all, start with the affected fields and exemptions. If you know it applies and you are working out whether the dates still fit your intake, that is the dMAT timeline.

The shape of the exam

Two parts, separated by a break, with one constraint that runs across both. The structure below is what the official material describes, not what the announcement summaries suggest.

The core module is three timed subtests

The core module measures general cognitive ability rather than anything you studied. It is split into three subtests, and each one gives you 20 items in 25 minutes. That is an average of 75 seconds per item, which is the number worth internalising, because none of the three task types rewards a slow, careful approach.

• Figure Sequences. A series of matrices in which figures move, rotate and change colour according to rules. Movement can be vertical, horizontal or diagonal, figures bounce off or travel along the outer boundary, and a rule can accelerate step by step. You choose the next two matrices in the series.
• Mathematical Equations. Small systems of equations where each letter stands for a whole number between 1 and 20. There is exactly one solution that satisfies every equation, and you have to find it.
• Latin Squares. A 5x5 grid, partly filled with letters, where each letter appears once per row and once per column. You decide which letter belongs in the marked field, which often means filling in other fields first.

The preparation material carries six practice items per subtest, two each at low, medium and high difficulty, with the full solution path written out. That is the closest thing to a syllabus that exists.

The subject module is not your subject

This is where most of the circulating advice is simply wrong. The subject module used for the APS route is called the General Academic Module, and the word to notice is general. The official material states that the topics span mathematics, computational sciences, natural sciences, engineering, business administration, economics, social sciences and humanities.

The four worked examples in the material make the point better than the description does. They cover vector calculations, hydrostatics, the optimal order quantity model, and research strategies in empirical social science. An engineering graduate will meet a text on qualitative and quantitative research design. A commerce graduate will meet vectors and buoyancy.

Each task follows the same shape: a text that introduces the concept, including the formulas and definitions you need, then a set of single choice questions with four options each. The questions test whether you can apply what the text just gave you. The material says so directly, and the design shows it: this is a transfer test, not a recall test.

You cannot write anything down

The instruction appears in the general section of the material and is then repeated at the end of every single core subtest: notes are not permitted throughout the exam. No scratch paper, no aids, nothing to write on.

Read that against the task types and the consequence is concrete. A system of four equations with four unknowns has to be substituted and rearranged in your head. A 5x5 grid has to be partly solved mentally before you can name the letter in the marked field. In Figure Sequences you have to track several figures across three matrices without sketching where each one went.

The material spells out the implication for practice, and it is the single most useful line in the whole document: work through the exercises without taking notes, because you will not have any help available in the exam either. Anyone practising with a pen is training a skill they cannot use on the day.

Three hours of testing, not a three and a half hour sitting

The figure that circulates is 3.5 hours, and it is not wrong so much as misread. The official material puts the exam itself at about three hours, with a 30 minute break between the two parts. The task time is 75 minutes of core module plus 90 minutes of subject module; the rest is instructions and setup, and the break sits in the middle rather than at the end.

It matters for one practical reason. If you plan your day around a single unbroken three and a half hour block, you will misjudge both your arrival window and the point at which you can eat something. Treat it as two sittings with a real pause between them.

What preparation can realistically be

• The official material is the source. The detailed instructions for each task type exist only there. In the exam you see short reminders, not the full explanation, so the first time you read the long version should not be on test day.
• Practise without writing. Every exercise, every time. This is the constraint that decides how the core module feels.
• Do not chase a syllabus for the subject module. There is none to chase. Practise reading dense text from fields that are not yours and answering questions about it quickly.
• Answer everything. The material explicitly tells you to guess when you do not know, so leaving items blank has no upside.
• Remember what the score does. There is no pass mark. The result is reflected on your APS certificate, and each German university decides for itself how to weigh it. A weak score does not by itself refuse your APS certificate.
