I am about to take the 5-week summer session of Calc III. I did Calc II over summer before and did well, but it's been a while and I've forgotten a lot. So I am reviewing some stuff to be sure I'm ready.

I totally suck at the nasty evil trig integrals with like five nested IBP steps now. Does anyone have any insights as to whether I actually need to be good at these to do well in Calc III? Or are these left to rot in Calc II?

Some people I know in engineering have told me Calc III has almost nothing to do with Calc II and that it's much easier... is this true? What is most important for me to review from Calc II?
