Its actually similar in the US at many schools. At least for bachelors degrees If you don't obtain a degree within ~5.5 years (this was the standard in University of California schools, where I went at the time, not sure if its changed) you're kicked out and told you need to go somewhere else to finish. This is mostly to make room for other students. And at least when I was in college it was the same with respect to classes, you can't take the same class more than 3 times. Additionally if a course is required you either take it or make the case for an equivalent class.
