<p>Not really for the AP's, but how long do you thing it would take me to self study A/B and maybe B/C?</p>
<p>To get on the AP Calc AB level, 3 months if you’re motivated and good at math</p>
<p>Oh, so we’re these people just crazy to say it could be done in a matter of days?(one guy here claimed to do it in 15 hours)</p>
<p>You can learn the conceptual parts of calculus really quickly, even 15-30 minutes if you wish.</p>
<p>Learning the actual differentiation/integration rules, on the other hand, takes time. Give yourself a few months for AB. If you enjoy AB, BC shouldn’t be hard at all, and might only take another few months.</p>
