TestAS Timeline: When to Take It for German Universities

TestAS is required for the Bachelor/Studienkolleg route and the German student visa. Learn when to register, when to sit it, and how to prepare with a free plan.

Key facts

Frequently asked questions

When should I take the TestAS?

Register a few weeks ahead and sit TestAS several months before your application deadline — typically 6-9 months out, since it's commonly required for the Bachelor/Studienkolleg route and for the German student visa. Results normally take a few weeks to be issued, so build that buffer into your plan; don't assume you'll have your score the same day you sit the exam. Because sessions run only a handful of times a year and seats at popular test centers can fill up fast, the safest approach is to register as soon as a session opens rather than waiting until your preparation feels complete — you can always keep studying right up to test day. If your target intake is competitive or you're unsure of your readiness, sitting an earlier available session leaves you a real fallback: enough time to retake it once before the application window closes, rather than being stuck with a single, high-pressure attempt.

What subject modules does TestAS offer?

TestAS offers four modules: Engineering, Economics, Mathematics/Computer Science/Natural Sciences, and Humanities/Social Sciences. Choose the one matching your intended field of study — most universities expect the module to align with the Bachelor's program you're applying to, and some will not accept a mismatched module at all, so check your target program's specific admission requirements before registering rather than guessing. Each module tests reasoning skills relevant to that broad field (e.g. quantitative and formal reasoning for Mathematics/CS/Natural Sciences, or text comprehension and reasoning about social situations for Humanities/Social Sciences) rather than subject knowledge from a specific degree program, so no amount of pre-university coursework substitutes for practicing the actual TestAS question formats. If you're genuinely torn between two related fields, check a few of your target universities' admission pages first, since the module choice is fixed once you register and can't be changed later without an entirely new, paid registration.

Can I retake the TestAS if I am not happy with my score?

Yes, but the test provider limits how often you can sit it within a given period (historically once per testing period, with multiple periods per year), and each attempt costs a new registration fee — there's no discounted "retake" rate. Since sessions are infrequent and seats can be limited, treat your first sitting as the one that counts and prepare accordingly rather than planning on a quick, low-stakes retake. That said, if your first result does come in lower than a program's typical range, retaking is a legitimate strategy as long as your timeline has enough slack: build in at least one extra testing window before your application deadline so a retake, if needed, doesn't force you to either submit a weaker score or delay your entire intake by a semester. Universities generally consider your most recent (or sometimes your best) TestAS result, so a genuine improvement on a second attempt is not held against you.

Is TestAS required for a Master's degree in Germany?

No — TestAS is specifically an admission tool for Bachelor's and Studienkolleg applicants; it was designed to assess general cognitive abilities relevant to undergraduate study, not the specialized knowledge expected at Master's level. Master's programs instead assess applicants primarily on their existing Bachelor's degree and transcripts (grades, especially in subjects directly relevant to the Master's program), and sometimes add a program-specific aptitude test, a written motivation statement, or an interview — the exact mix varies by university and department, so there's no single standardized Master's-level exam equivalent to TestAS. If you're planning a Bachelor's-then-Master's pathway in Germany, TestAS only matters for the Bachelor's admission step; once you're evaluating Master's programs, focus your preparation on strengthening your Bachelor's transcript and researching each target program's specific requirements instead.

How long is the TestAS exam?

The full TestAS takes about 4–4.5 hours in total, combining the Core Test with your chosen subject-specific module, and is sat at a computer-based test center rather than on paper. Because sessions run only a handful of times per year and popular test centers can fill up quickly, register as soon as a session opens rather than waiting, since a full sitting requires blocking out most of a day and travel to an approved test center if there isn't one in your city. Plan to arrive well before the start time, since test centers typically run identity checks and briefing before the exam begins, and factor a recovery day afterward if possible — 4+ hours of sustained cognitive testing is genuinely tiring, and pacing yourself across the full session matters more than sprinting through the first hour.

How do I send my TestAS results to universities?

TestAS results are issued electronically through the official TestAS portal, and you can forward them directly to universities and to uni-assist from there rather than requesting a separate paper certificate. Keep your portal login details safe well after test day, since you may need to resend or re-verify your result months later — for example if a university's document upload fails, or if you apply to an additional university after your first admission round. Because uni-assist and individual universities sometimes have different submission processes (some accept a direct electronic transfer, others want you to upload a downloaded certificate yourself), check each target university's specific instructions rather than assuming one method works everywhere.
