About Aptitrail, and how the practice is made

Aptitrail helps learners practise reasoning for Germany’s digital Master Test with original exercises and explanations.

Independent practice

Aptitrail offers original learning material and clear purchase policies. Read the published purchase policies before choosing Premium.

Support and grievances: use the Contact and feedback form. Requests are reviewed by the Aptitrail team and handled manually. Submitting a form does not automatically email a support team. You can track your reports in Account. Include a question ID for a content issue or a purchase reference for an access issue. Never send passwords, sign-in codes, card credentials or a UPI PIN.

Original content and its checks

The practice bank and public teaching examples are original Aptitrail material. They are separate from official exercises and are not leaked questions or official past papers. AI assistance and automated tests are used in content preparation and verification. Our checks cover the stated mathematics, constraints and supported rules; publication approval does not establish independent expert review or official exam difficulty.

Public examples explain the deduction and link to matching practice. Empirical difficulty calibration and independent subject-expert review remain separate work. A practice percentage is not an official score, percentile or admission prediction.

Help us correct a mistake

Use the report control next to a practice question, or follow our correction guidance. Describe the disputed step and your alternative reasoning. A report starts an investigation; it does not automatically establish an error.

Keep official decisions with their source

Aptitrail is independent and is not affiliated with or endorsed by dMAT, g.a.s.t., APS or any university. Confirm test dates, registration and examination instructions with the official dMAT India FAQ. Ask APS India about individual requirement questions and the university about its admissions rules.

Read the privacy information and current web offer before sharing information or paying. Free practice does not require a purchase or optional marketing subscription.

Frequently asked questions

Can I practise without an account?

Yes. The short free diagnostic and catalogue of 65 free questions need no sign-in or payment. An account lets you keep progress across registered browsers.

Are these official dMAT questions?

No. These are independently written practice exercises. Aptitrail is not affiliated with dMAT, g.a.s.t. or APS; practice scores do not predict official results.

Will I get new questions when I repeat a free set?

Guides, samples, the diagnostic and free practice reuse the free catalogue. Repeating a set helps you review the method.
