IB Importance

I’m currently a US high school student, but I am looking into going to college in Germany and eventually living there. I’ve been trying to find a way to take German as a language course within my school, it isn’t offered as an official course. I found a way to take it online that would work perfectly, the only problem is that I can’t take it as an IB course as far as I can tell. Is the IB diploma really that important or would it be more influential to take the language of the country I plan on attending in?
