Question 1

Which exam should I pick: Goethe, telc, or TestDaF?

Accepted Answer

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.

Question 2

How long do I need to prepare?

Accepted Answer

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.

Do you prepare for C1 and C2?

Accepted Answer

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.
