Northeastern GPA and SAT

Agree that they NEU has really high stats. Re: GPA - makes me wonder how NEU calculates GPA, do they count honors and AP the same or give a plus for AP? Do they include electives APs or honor courses? How do they quantify a students GPA if their school doesn’t offer as many APs as other schools do (so a 4.16 GPA out of 4.333 is going to be better than 4.4 out of 5.0). Anyway, they publish these GPA stats but don’t give the intel on what they actually mean.
