Today I asked an upper-classman friend of mine what she was doing currently in pre-calculus. She told me shes doing differentiation, I woulda guessed that. However, she has a friend in calculus AP and I asked her what they did in AP, if she knew, since I'm planning on taking AP calculus my senior year, and she said they're doing differentiation as well. Its almost the end of the semester there's only 4 weeks left so I guess my high school doesn't get into integral calculus. So I was wondering, once I get into college and start taking calculus in college, will it jump right into integration or continue differentiation and then get into integration? If the first is the case, should I study integral calculus and try to be ready for integrating?
