You need to read the textbook a lot to understand what's going on.

I came into this class having taken AP Physics 1, and it's basically a repeat of that course, but VVV makes it harder. Honestly, if I came in not knowing anything I would've been a lot worse off; most of what I knew came from high school, and trying to relearn concepts in this class confused me more. Reading the textbook was very helpful, and all the homework came from the textbook. If you do all the homework problems, you get a bit of extra credit from that, which is very much needed after taking the midterms and especially the final. At one point in our final everyone was so confused VVV started trying to explain the problem on the whiteboard.
