She plans to stay 4 years in HS and take 4 history classes. Fortunately, the school offers many core and elective history courses.
@Tigerle,
I agree. DD worked very hard for those courses, sometimes studying through the night because the courses were challenging (but still within Zone of Proximal Development) and she still wanted to excel. She worked much harder than she would have in regular courses, and her understanding of the world and writing skills have greatly improved through them.
