I want to start study in Germany and I must have a German certificate. I have these possibilities:
- Goethe-Zertifikat C 2 (Goethe)
- DSD II
- TESTDAF (das in allen vier Teilprüfungen die Test-Niveaustufe 4 ausweist)
- TELC Deutsch C1 Hochschule
And my question is: is one of them simpler to pass than other? Or is level of difficulty similar and this is rather a matter of costs and other preferences?
