Yanidel, you'll notice I said my viewpoint is limited as well. I'm not arrogant enough to think that I understand what is going on at other departments or universities or other universities in other countries. I don't see how you could either, hence a limit to one's ability to generalize or extrapolate beyond their experience.
As for research on the internet, no thanks, but I am aware of the falling test scores. I'm also aware that some professors will rarely take on graduate students from certain countries, countries with very high test scores, unless they've had a significant amount of time with the prospective student. They had enough experience with students who looked great on paper, who could recite a whole text book, but could not formulate their own research study or think on their feet when things turned 'interesting'. They could have generalized and excluded anyone from that system, but instead they continued to treat them as individuals and see if they were going to be a good fit.
If we judge things not on test scores, but say, on contributions to a field of study, should we generalize on the success of a system from those results? I don't think so, since there are many factors involved other than a score of contributions (big bucks, as you put it, for one).
Back to the original poster, if you are really concerned about the fairness of your grade, I'd recommend you mention to the teacher your concerns and whether you should arrange a talk with the teacher and the dean about it. If nothing else you can communicate clearly that your critique was not meant to be personal, and given that it wasn't, you are still interested in her response to the things you brought up.
