The "one time" you got a high grade on an exam after a night of drinking isn't reason enough to denigrate the Canadian post secondary system. Undergraduate studies for the reasonably intelligent are easy. Everywhere. There's some variance. But it's not much.

If you don't believe me, take a look at all the free courses available on the web(MIT especially). The courses are not exceptional or exceptionally rigourous. Pretty standard undergrad fare.
