Is this rumour about the University of Toronto true?

I heard U of T accepts all people into school the first year, but flunk you out during second year. Apparently 50% flunk out. It depends on your major, since 80% of first year math majors will flunk their first math class. A guy told me a C+ in computer science was considered a very high grade. I know a B-grade computer student who got the highest grade in his class.
