Are These Courses Considered Core Science Courses or Electives?
Whether a homeschooled student could count completion of any of our courses as a core science course or as an elective would really depend on your state's homeschooling laws and is not something we can directly advise you on.
However, one way to better determine what is typical practice in your state is to visit the high school websites for the most affluent districts in your state. You're specifically looking for high schools in districts with the most resources and typically the widest range of high school class offerings. From there you can often see if this sort of course is offered as a core science course or an elective within that school.
