I would guess 80% of the career value is captured by satisfying admissions and graduating. I think the actual grading isn't looked at except to rank similar peers for admission to other competitive programs.
This is exactly why companies should drop degree requirements. If 80% of the degree requirements are met when you graduate from HS (and I would say it's more than 80%), then why make them wait 4 years and take on a pile of debt?
