If you're a fantastic math PhD, then it's just a matter of answering one or two questions for each one (I think Khan gives you more credit towards mastery the faster you answer questions, at least at first). So let's assume we're talking about the remaining 390 exercises, Algebra through Integral Calculus. Khan Academy’s 100,000+ free practice questions give instant feedback, don’t need to be graded, and don’t require a printer.Right now (Jan 1, 2015), there are 926 math exercises on Khan and 536 of them are for grades K-8.
