[quote=Anonymous][quote=Anonymous]My kid is a paid peer tutor at an Ivy for the equivalent of Calculus BC and DCUM would be shocked at how little math many kids know when they arrive and how poorly many of them do. [/quote] Not surprised. A 5 in Calc BC merely says that one could solve 60% of the problems on the day of the AP exam. 60% -- what a low bar! And the 60% can easily become 30% three months later, when they start their freshman year, contributing to what your kid observed as a tutor. My kid also got a 5 in Calc BC (and 790 in SAT math) but when I asked her why the derivative of x^2 is 2x, or why must the second derivative be positive at a local minimum, she could only respond with "that's the rule." She can competently differentiate and integrate functions for the purpose of the AP exam but she doesn't really understand why those rules work. I expect her to have forgotten most of these rules in August when she starts college :([/quote]
