<p>AB should pretty much be for kids who take Precalc as a junior and are decent (but not outstanding) at math. If you have the privilege and talent to be taking Precalc as a sophomore, two years ahead of schedule ahead of the average kid, taking BC shouldn’t even really be an option. </p>
<p>It just doesn’t make any sense - it’s like putting training wheels on an Olympic cyclist’s bike. Why stretch one semester of work into an entire year for a student (as that is what is done in AB) who is so outstanding at math?</p>
