What about the demands on the time of professors from students who repeatedly try and fail the exams? Seems like that could get expensive for taxpayers.
Maybe it doesn’t happen much in practice?

That said, in my country (in EU), it's not indefinite tries. The fourth and later attempts (up to 8, I think) have oral exams in front of a panel of professors so that they can evaluate if there is actual lack of knowledge or if there is some sort of problem between the student and the professor. The student must by then pay for the attempt to pass the exam. It's not expensive, though, it's just another incentive to make the student really be sure to be prepared.
