Human Geography for AP credit is, and always has been, worthless for Harvard, as they do not give AP credit. Any discussion of AP credit, though, is pointless since it will be eliminated for those students entering starting in 2020, although individual departments can continue to give course waivers based on exam scores.
AP courses on the other hand are important for course rigor, to an extent. So the 7-8 next year,as I said before, is too much of a good thing, as the is no course rigor rating of super-duper demanding.
Same at Harvard,although we’re getting ahead of ourselves.
Ditto. Although many gov concentrators (as poli sci majors are termed in Harvard-speak) opt for the calc-based stat class which, as @ucbalumnus correctly points out, may prove more useful in the long run.
