EdX has begun to offer FREE online AP classes to students! EdX is currently offering AP STEM courses in Biology, Chemistry, Computer Science, Physics, Algebra, Geometry, Calculus, and Environmental Science. These courses are taught by instructors from top institutions including Boston University, MIT, Georgetown, and Rice University.
The courses use game based learning as well as the flipped classroom model and are intended to help give future students a leg up on getting into college. The materials are also FREE to teachers to allow them to build more AP style work into classes. Remember that AP and IB are not the same thing but the classes may help you out!
