@rl: not necessarily true. Some people have their potential reduced because of lack of competition. Not having any real competition makes undergrad no different than highschool for me. I can't operate at my full potential due to a lack of motivation stemming from undergrad being too easy.
@Sky: I definitely agree with you there, I have the same issue actually. My lowest mark in undergrad is in one of the most easy courses. My highest mark in a course that's considered quite hard. Doesn't change what I said about OP though. I'd say 99% of the people who say smth like that are just too stupid to realize their stupidity (that's an actual effect too).
@6: I know how tutors are hired so I'm not surprised. No offense. Also, you're not determining the student's grades per se.
Before this turns into a "my marks are so high" bullshit let me just say that courses were created for the sole reason of letting people pass.
If you have a course too difficult then very few people will attend resulting in higher costs/fees, ie. texts and possibly the course itself. But if you have a dumbed-down version then you create more demand which in turn lowers costs. This is currently happening in university resulting in a educational bubble.
* Just had to add that universities are not lowering costs with the additional enrollments, nor are the provinces funding universities to the extent they had in the past. Hence the bubble, diluted education at premium cost..
