I have a 7.67 on 10 GPA from IIT. When I passed out from school it seemed decent to me. But if I do a linear transformation to the 4 point scale my GPA is 3.1, which is a bit on the lower side for the programs i am targetting.
My question is - should I explain my GPA in the optional essay OR do the the adcoms treat GPA from IITs or international univs differently from the US GPAs.
BTW I have a 760 in GMAT.
