I am a high school math teacher, and I don't even know the answer to that question. If I had to guess, I would say that the GE is comparable to what the average 11th grader is doing, which is Algebra II in my state. Here, the advanced kids take Precalculus in 11th grade and Calculus in 12th (Cal I or Cal I and II depending on their ability). It's rare for kids here to complete Calculus in 11th grade. However, it's the standard at my school, which is a magnet school for GT kids.
