<p>@beth’s mom, I don’t think your high school is typical. Two thirds of our high school doesn’t even start algebra until 9th grade, about a third start in 8th and a tiny handful start in 7th. The typical sequence is Algebra 1, Geometry, Algebra 2, Pre-calc, and then either AP Statistics, AP Calc AB or AP Calc BC. Those who get ahead of that sequence (either by being in the tiny group that petitions to take Algebra in 7th, or that jumps ahead, usually by doing pre-calc in the summer) has been able to take a Linear Algebra course at the high school senior year. Even MIT offers a freshman Calculus 1 course, because believe it or not there are kids who don’t get calculus in high school.</p>
