Relax. Am from BITS Pilani and mine amounts to 7.9
The international applicants from regular feeder universities are not required to a linear transformation to 4.0 scale.
Its not the same thing. Its the reputation of our universities that matter and we are good in that aspect with 7+ GPA. It is not extraordinary like a 9+ would have been , but respectable eough for an admission to HSW , provided you have a 700 + and admirable work credentials.
Although you should explain in the optional essay if say, you had a bad semester or a couple of E grades which you took up in the next semester. Unfortunately, I fall in this category, but the rest of my stats give me an enviable position to overcome that weakness.
