<p>Engineering students may still wish to take Calc 1 and/or 2 at college, even if they already have AP credit. Regardless what the AP marketers claim, HS AP classes really aren’t equivalent to college classes. Engineering depends so much on good Calc fundamentals, so it is important to have a really solid footing.</p>
<p>When I was an undergrad (a very long time ago) I started out as a freshman taking Calc 3, after my AP Calc BC test placed me out of Calc 1 and 2, and boy did I struggle that first semester. The college did not have a perfect alignment in curriculum with the AP material. If I had to do it all over again, I would have started with Calc 2, not Calc 3.</p>
