Isn’t RPI infamous for grade deflation? The average GPA is around 3.2. I’m not sure if the math major might have a higher average due not being an engineering major.
Fun fact: I talked to a former T5 med school adcom who said they gave a boost to students from top schools due to their rigor. I asked about Brown and RPI and he said Brown students got the boost but RPI wasn’t on the list.
