I don't know but I do know the kids at our school can start algebra I in 7th grade. I think we're the only school around here that does it that way. Then they do geometry in 8th, algebra II in 9th, trig in 10th, calc I in 11th and calc II in 12th. But as far as what type of math the GE corresponds to, I'm not sure but I'm sure someone else here does! smile
