German language exams help

Okay guys need some help so im currently at A2 german level yet to clear goethe. I have been preparing for Goethe for university but the requirement if doing goethe is you need to be C2 and in the 1.5yrs of time i have i don't think its doable.

TestDaf requires you to be at level 4 and DSH level 2 and telc Deutsch C1 Hochschule examination. Which amongst these options would be the best to go for thats easiest to clear just for the sake of getting the certificate with a decent grasp of language just to get by for now.`

Any help is appreciated!
