Will I get rescinded?

I got into NYU Stern through ED2 and have committed.

I have 2 As and 4 Bs right now unweighted but 4 As and 2 Bs weighted. My unweighted GPA before acceptance was around a 3.8. Is this grounds for rescinding admission?

No. They’ll only rescind your admission if you get multiple Cs/Ds or if you basically fail.
