Question 1

How exactly does the Zertifly platform work?

Accepted Answer

Zertifly uses advanced AI to analyze your language skills. It evaluates your writing and speaking exercises instantly, detects your mistakes, gives feedback and offers personalized suggestions. It includes exercises that match the real format of the TestDaF, Goethe and telc exams, with dedicated practice sections for every skill (Reading, Listening, Writing, Speaking; plus Sprachbausteine for telc).

Question 2

Which German exams does Zertifly prepare me for?

Accepted Answer

Zertifly brings the three major German exams together on one platform:

- **TestDaF** — the academic exam for university (TDN 3–5 / C1 level)
- **Goethe-Zertifikat** — a globally recognized official diploma (currently A1 and A2)
- **telc Deutsch** — a certificate to European standards (B1 and B2), including the Sprachbausteine section

For each exam we provide exercises that match its real section structure and scoring logic. The content library keeps growing.

Question 3

Why should I use Zertifly when I already have ChatGPT or Gemini?

Accepted Answer

General-purpose AIs (ChatGPT, Gemini, etc.) are useful for German practice, but they don't have the scoring logic and nuances of exams like TestDaF, Goethe or telc. That's exactly where Zertifly stands out: **specialization**.

Our systems are trained on each exam's official scoring criteria (e.g. TDN 3, 4, 5 for TestDaF). So instead of just a grammar fix, you get consistent feedback from an examiner's perspective, aimed directly at your exam goals. Detailed progress tracking, an exam-specific vocabulary pool and a personal Redemittel bank bring your whole preparation together in one place.

Question 4

How are my writing and speaking answers evaluated?

Accepted Answer

Your writing (Schreiben) and speaking (Sprechen) answers are scored instantly by AI trained on each exam's official criteria. You see your strengths, the points to improve and concrete example-based suggestions; you also get text-improvement and alternative-phrasing tips. An exam-specific vocabulary pool and a personal Redemittel (set-phrase) bank further support your preparation.

Question 5

Can Zertifly be as effective as a real teacher or course?

Accepted Answer

Zertifly isn't a replacement for traditional learning — it's a complement that makes it far more efficient.

Its biggest advantage is providing 24/7, instant and fully objective feedback that a teacher can rarely offer to every student continuously. Our AI analysis always measures your performance against the same consistent criteria, so you can see your weak points backed by clear data.

Question 6

Who is Zertifly for?

Accepted Answer

For anyone preparing for a German exam: TestDaF candidates who want to study at a German university, those aiming for a Goethe certificate for a visa, residence or general proficiency, and people taking telc for jobs, residence or professional recognition. It offers comprehensive support for first-time test-takers, retakers and learners of all levels.
