Quick note: C., who has left his calculus course for statistics (thank you all for the advice), just told us the calculus teacher is giving his students an essay test. Just to review: this is a calculus class populated by kids who learned next to no precalculus last year. They're in calculus, they don't know any precalculus, and...they're taking an essay test.
Ed said, "You should have stayed in the class. You could have raised your grade."
That was a joke. We both know it's not true. If C. had stayed in the class, he would have done worse on the essay test than he did on the math test, I'll wager.
Must get Allison's Comment about charismatic teachers pulled up front.
C. loves statistics. Loves! First math class he's ever felt that way about.
