I have talked with college professors; they are not allowed to fail anyone, anymore, or are severely pressured not to. The applied pressure is to protect minorities, keeps the federal government off their backs. Only teachers with tenure will challenge the pressure coming at them.
I absolutely believe that; employers quickly realize the difference between a real degree and an “honorable mention” degree. We use a couple of tests to determine math & English skills, because there is no assurance that a degreed applicant has either (despite the fact that these subjects are usually included in the “general education requirements” - high school-type classes outside of your major required for a degree).
A simple one-paragraph essay can usually separate the wheat from the chaff.
