There is no uni degree in Germany that requires english or proper english, why should it?
Out of the three or four languages Europeans are supposed to learn English isn't one of them? No wonder the Brits left the European Union in a huff. ;)
On the other hand, what do you find wrong in his sentence?
How it was written contradicts the statement that the OP graduated from a university. He came across as being a graduate of American public schools, which is what a university education is supposed to fix. If you run the text through a readability measurement, it comes out at the fourth grade level. I never went to high school, I got an A.A. degree in General Education, transferred and got kicked out of the university in my junior year, and I later went back to get an A.S. in Computer Programming with a 4.0 GPA. Despite not graduating from high school or the university, I write at the 11th grade level. The average American reads at the seventh grade level.
