You’re Doing Your Calculus Homework Wrong! bprp calc basics 2026-02-25 | As a community college instructor since 2012, I notice many calculus students have a big problem. They are doing their homework wrong! Not that they get the wrong answer, but they don't have the right approach or the mentality for doing the homework. Doing homework is not about getting the points (it's a small portion of your overall grade anyway). Doing homework is so that you can see if you can do the problems 100% on your own or not. I will show you how to approach doing your homework so you can gain confidence and feel good about the math! I will also give a bonus tip at the end.
