AP CALC BC v.Slacked off the first semester

<p>Alright, about to start my second semester and school, and i want to do well on the AP Calc test. I slacked off a lot the first semester but still managed to get a B. However, i’m really behind and need to catch up somehow since it seems like a lot of the stuff we’re going to do relies on us knowing what we did in the first semester. How would u guys go about getting caught up?</p>

<p>Same thing happened to me in AP Physics. Although I did get an A in the class, I don’t know I know much of the stuff because I get 40’s on exams. Any help will be appreciated.</p>
