I'm fine with expecting more, but for those kids who just don't handle it well, it's not right to make them pariahs, just take the math down a notch. I saw kids treated as “less than” because they weren't making it in a certain level of math, and that always pissed me off. Likewise, I even had to report a calculus teacher once anonymously, I recorded the class with a mini-cassette (in the late 90s) recorder and slid it under the principal's door with a note. No the kid wasn't me, but he was a decent guy who I knew a little bit and knew he was trying hard but just couldn't get it.
