> teacher/student ratio and class sizes are much worse in Germany That very much depends on the subject. In CS I even had classes that took place in the office of the professor because there only were a handful of people. For seminars we went into a hotel in the middle of nowhere for a few days with about a dozen people total. If on the other hand you study BWL (business administration) during the first year or two it's very crowded in even a large auditorium. That's because that is what all those people end up signing up for who don't really know what they want, and "business" always is the fallback and safe choice for many. The more concrete and STEM-y your field the less of that problem you will ever see.
