Which exam should I pick: Goethe, telc, or TestDaF?
+
Studying at a German university? TestDaF. Working in Germany or the EU? telc. Need a globally recognised certificate or a CV line? Goethe. We'll also recommend one after the diagnostic.
How long do I need to prepare?
+
Most learners go from B1 → B2 in about 12 weeks with ~25 minutes a day. C1 takes longer — plan for 16-20 weeks. The app adjusts your plan automatically based on your diagnostic and pace.
Is this better than a prep course or a tutor?
+
It's cheaper, more consistent, and adapts to your weak spots in real time. AI feedback on writing and speaking is calibrated against real exam rubrics, so you get examiner-level guidance at a fraction of the cost.
How accurate is the AI feedback on my writing?
+
It's calibrated against rubrics from 3,200 real graded exam scripts. Our predicted score lands within ±3 points of the actual exam result 87% of the time.
Do you prepare for C1 and C2?
+
Yes — B1 through C1 are fully covered for Goethe and telc. TestDaF is only offered at the B2/C1 range natively. C2 (Goethe-Zertifikat C2 GDS) is in closed beta — join the waitlist from your dashboard.
What does "pass guarantee" actually mean?
+
If you finish at least 80% of your scheduled plan and attempt all three mock exams, and you don't pass your target exam on the first sitting, we'll refund the cost of Prep — or prep you free for the next sitting. Your choice.
Can I use prepdaf on my phone?
+
Yes. The web app works on any device — desktop, tablet or phone. Native iOS and Android apps are coming soon.
Will my employer or university recognise prepdaf?
+
We're a preparation tool — not a certifier. Your actual certificate comes from Goethe-Institut, telc gGmbH, or the TestDaF-Institut. prepdaf gets you ready to sit and pass the official exam.
