I have a friend who is just at the end of finish her university degree in Germany in a sub field of economics. She cannot calculate with fractions. She can also not write a 10-paged paper about shallow topics. I don't know what she can do tbh and I am really not trying to be arrogant or shitting on her. She uses her sister, who is smart but easily manipulated by younger sister with big pleading eyes, as a ghostwriter to pass all exams during Corona. And she really isn't the only one. Some universities are incapable of guaranteeing a minimum baseline of quality of their graduates.
