Hello, Since few days, I was looking forward to start some pre-calculus classes...but im kind of confused with the 'types' of classes offered. Oh and im in 9th grade...prob. I'll take it next year(its not available in my school, I will probably have to learn somewhere else,can anyone point out where? I live in Canada...so you know any the institutions offering such class) Ive heard AP,AB calculus and stuff like that?What are they o.0..? What should I take, I want to really begin, from the start, so pre-calculus is the class right? Can someone explain in details calculus classes that come before college...just a better preparation ;)..... Tips/Advices are appreciated.Thanks in advance!!!
