<p>Does anyone know of a Calculus 3 (Multivariable Calculus?) class I could take online for free? I took AP Calculus AB/BC and AP Statistics as a sophomore, except now I don't have any math classes to take. My school doesn't offer any math classes beyond Calc BC and AP Stats.</p>
<p>Don’t know of any free “classes,” but MIT’s Open Course Ware has videos of past lectures. You can go to YouTube and search “MIT OCW 18.02” or something (18.02 is the course name for multi-variable calculus).</p>
