Don't worry, the class is a joke.
Agreed. I did awesome in the class, and got a 5 on the test. The hardest thing you're going to have to deal with is recursion. (which is easy after like 5 minutes) You're also going to need to be familiar with the new
case study. There will be an open response question about it.
And uh, I dunno if you've ever used java, so you might want to at least familiarize yourself with it.
And take the AB test. You could pass the A in your sleep. According to the college board site the things you don't need to know for A are: two dimensional arrays, linked lists, stacks, queues, trees, heaps, priority queues, sets, maps, iterators, Big O notation, and throwing runtime exceptions. I can't imagine you having trouble with any of that
