Keep at it and you'll find that you're starting to learn the language. I had a base of it thanks to Rammstein but I realized a while back that I can get a gist of it, I've never taken a class or done Rosetta Stone or any apps like it but I'm slowly learning German by exposure. Reading only. So far it only works on intake, it's not like I can speak it or write it but I'm starting to understand it if I read or hear it.
