Why is everyone in such a rush to fault the instructor for not doing his job right? How about the student who does not do the assigned studying and tells you he should pass because he paid his money. I had such a student D.M. candidate once in a class of 4 he failed the physics repeatedly and with many hours of extra help from myself and his fellow classmates he still failed the class as he just could not do the math he even tried memorizing the answers to the A and B exam and still failed so who's to blame? Some people are just not meant to progress up the ladder of education it's just a fact of life that we are not all created equal in abilities even though society would like us all to feel warm and fussy and if were not let's blame someone else besides ourselves.
