It's true, my Calculus teacher in High School had failed Calc when he was in high school.

And the people who you wouldn't expect to do well, do. I don't like math and I got a B+ in Calc. (89.6%, and he wouldn't round it up to an A. )

But anyway, yeah, no one does well in Calc. Schools take that into consideration when they're looking at scholarships and stuff.
