Khan Academy last I checked went up to High School. MathAcademy goes up to undergrad math.

The last I checked, most high schoolers don't take Diff Eq classes.

I stand corrected. Can’t edit my original post, though.

Khan hides it well, though - it’s listed smack in the middle of sixth grade math and high school math courses. I skimmed through the list (again) and found some college math but not all. Maybe this is a new offering?
