I am not sure what the overall plan is for the senior year, but I would recommend AP Lang as the 4th, with Spanish IV. And AP Lit, AP Chem or Physics, and two others for senior year (maybe Stats, APUSH, Spanish, or Env. Sci.) Junior year is critical, since the GPA on the college application will be largely impacted by that year. Her recommenders will also most likely be jr. year teachers. Activities will need to be adjusted for the sake of academic rigor and mental health
