Has she taken Physics I or Physics C Mechanics? If so she probably doesn’t need more Physics particularly if she isn’t planing on an Engineering major. I assume she already has all the Social Studies/History? And some foreign language. What about AP Psychology if your school offers it. Or AP Stats. Looks like a rigorous schedule already. So another option would be to just look for something in the schedule that would be fun for her but still counts as a academic class, such as art, film, creative writing, music.
