Looking for computer based precalculus class
My daughter is taking Calculus in the fall. This past year she took a compressed math class that covered most but not all of the syllabus for precalculus so we are specifically looking for something where she can test out of subjects she's already covered.
We're discovering that many of the online class are just recreation of an in person course and that's not what we'd like. My son took a Elementary school course that was ideal called Redbird through Stanford, but that seems to no longer be available.
Has anyone taken anything similar? Or can recommend another solution I haven't thought of?
