Study in German Experts and German Visa Experts please help me reason my matter,

i plan to study Theology (Religious Program) faculty of Humanities, at any german university i saw University of Rostock offering it and other universities but they demand C1 as language requirement. as at now i only have olevel WAEC but i intend getting admission letter from NOUN as addition(upgrade) to my olevel result.

now my problem is this can i apply to these german universities without any German proficiency certificate such as GOETHE will issue.

can i get admission letter from a german university without having german LANGUAGE certificate.

secondly , seeing that german Language C1 is required and i percieve that such level(C1) Will be difficult for me to get, can i settle for A2 OR B1 . Will german schools grant me admission with such Language Level seeing that C1 is required by the schools.

Lastly, what is the required Language Level required by the German embassy during VISA aPPLICATION.

Please guyS i need advise on how to go about this. Italia has disappointed me and many of my colleauges . they shut down thier site for student VISAS. gERMANY IS now my next option.

please advise me on what to do.
