To be a bit more specific...
1st year sucks, class wise. Your schedule is full, if you are Science/Engineering it is more than full with your labs.
For the rest of it, it depends on the individual course. Some courses have midterms, some don't. Some people get very high marks, some fail. For all that RMC is "different" than any other university in Canada, the school part is not that unusual.
Your biggest class in 1st year will probably be one of the common core courses (Poli-Sci, Eng, Math, etc). After that, they steadily get smaller. Most of my 4th year classes had no more than 15 people.
