The history/social studies courses are all non-honors, non-AP semester courses like Intro to Psychology, U.S. Government, Genocide Studies, etc.
Another option would be to fill the slot with Honors Band (she plays flute) which is what she’d really like to do (in addition to Honors Choir), but that would mean a schedule with three non-academic classes (Band, Choir, gym) and no 4th year of history. Also no CS which could be helpful generally for a STEM major. Thoughts?
