Don't let them scare u, just try to do your best!!
Both McGill & Concordia do it - it's easy to get into program(s), but "intentionally" they fail over 50% of their students in a few classes. I don't know the exact details. Personal experience - only got passing mark(s), felt bad for it for over 10 years, once I came across their class averages/statistics, I was actually above 85% while 50 or 75% of the class failed.
