I find this "mortarboarding" practice to be a despicable one. You want the degree? Then you qualify for entry to university, study for years, pay your fees and pass all the exams. Not only do I have no respect for the process, I instantly lose any respect I might have had for anyone accepting such a degree. Surely they can decline the offer, even if it is an offer from an alma mater.
