My PG daughter (13 years old) is looking to take additional coursework - she attends a (somewhat) traditional school during the day - so we were thinking maybe something online would work. She applied to Stanford OHS - but is looking at something for now as well. She is thinking maybe of History and/or Biology or something interesting off the beaten path. I looked at BYU and it is very cheap, self paced and has some interesting looking courses. Any thoughts or recommendations?
