Did you take Quantative Analysis and General Physics? Class avgs were like 60% on a curve. I doubled Bio and Chem. Also took Parasite Bio, and chicks would leave class crying after exams.
I did not take quantitive analysis. I took General Phyics in first year, and it was brutal because we were expected to know certain techniques of integration and differentiation (ie integration by parts and partial derivitives) that we had not learned in first year calculus yet

Class average in gen. phyics was a D+
In first year bio it was a D.
I still cannot figure out why they never curved anything.
Personally, I found first and second year to be total "weed out" years.
Advanced cell bio and organic chem being classic examples of these.
Personally, I found third and fourth years to be no harder in terms of academic difficulty than first and second years. I guess "university level" is university level, no matter what the year. But the volume of work required and the speed of the course in these was double or triple that of the first year..
I did a college post grad diploma program after and it was a breeze.
As Matt will tell you, here in Canada, "community college" is a peice of cake compared to our Universities. University is very difficult by comparison.
Colleges in canada do not grant degrees, only diplomas, although many now have joint programs with local universities in which they can be offered by doing courses on both campuses at both levels.
