<p>Is Mat21 a high math class or is it a low one? I graduated high school with a pre cal class, so is this class higher than that one?</p>
<p>Math 21 is the highest calculus series (with the exception of the honors series.)</p>
<p>What is the difference between Mat21A, B, and C?</p>
<p>21A: derivatives
21B: integrals
21C: multivariable calculus</p>
