I can only speak for one school that cannot be named (to protect my privacy) but the curve is set such that failing is any score >2 standard deviations below the mean and there is a little sliver above that labeled "barely passing" (they have a fancier name for it) so that those who barely passed are notified that they came close to not passing and should know that for next time. Everyone who fails must remediate during the academic year or later (but before boards which come at the end of 2nd year). Also, if a question on the exam turns out to be confusing or poorly worded as evidenced by a large proportion of the class getting it wrong, the question is thrown out and not included when grading the exam.
AFAIK, this has no relationship to anything in the undergraduate colleges of the university.
