When I went to college in the 80's, there was a forced curve on all tests. Only 5% of the class got A's and 5% of the class failed. While I dont like this method myself, putting this policy back into place prevents this from happening.
IMO the correct way to design a test is to make it hard enough that the median score is around the 50% mark in order to capture the entire bell curve of performance, but then curve it enough afterward that everybody who met the standard the professor was actually trying to teach gets a good grade.
