Did the gym coach tell you how it was being marked? Because, if he did, then you had a clear success criteria, and you failed to follow instructions.
Why did you go to college? Why were you in class? A lot of people answer that question by saying, "to get a degree." That's not right though, because there are cheaper ways of getting "a degree." You can buy one for much cheaper than college tuition, and for much less work.
So the next justification is that you can't use the degree you buy from a non-accredited university to get a job. Why not? Because employers expect that the degree means you have learned a minimum set of per-requisites they require in their employees. In fact, you're often asked to provide an official transcript, which shows the grades you got in specific classes they may deem relevant for the position you're applying for. With this in mind, would someone who was told how they were being graded really have a clear success criteria?
They'd have a way to achieve a high grade in the course, but that's not success. If I achieve a high grade in the course, but the grade does not correlate to my understanding of the material the class is supposed to cover, the professor failed my success criteria, by giving me a transcript that means nothing to the employers. When I go to an interview fresh out of college I'm being judged by degree, by my grades, and by comparison from other candidates who may have come to the same school, and taken the same classes. If an idiot classmate I had interviews first for a job I'm interested in demonstrates a complete lack of understanding of the subject matter in an interview, despite having a despite having a degree in the field and a high gpa, then he may have cost me the ability to even get an interview at that location. Now the employer is thinking, "that university sucks for that degree, that guy's grades didn't mean shit. I'm not going to waste my time with this next guy."
But no one is claiming that the universities are deceiving candidates - they're just requiring quantity, not quality.
Which is deceptive to me, because I pay the university with the understanding they will train me in the field of my choice, and evaluate me fairly with regards to the knowledge that i've gained. Anything else, and I'm just throwing money away.
Similarly, a professor who is capable of writing a few quality papers is far more valuable than one who can write hundreds of low quality ones. The universities make their standards clear, but they're not selecting for what they're supposed to, and it's leading to lower quality of education.
