I am in complete agreement with the rest. A 3.7/4.0 is quite good. Well done to you. I do not see why you need to compensate. But to answer your question, I once knew a girl who was Pickering Fellow with a 3.4/4/0 who got into Georgetown's School of Foreign Service (SFS). With that said, do the math. Regardless of the fact that she was a Pickering Fellow, which might have caused the selection committee to see her GPA as more like a 3.5/3.6, SFS is one of the hardest programme in the world to get into.
She had a really good GRE score plus God and an amasing title a Pickering Fellow next to her name. You just don't worry; you will do fine and you really should refrain from comparing yourself to others'it will be a constat losing game in the world of academia!
I hope this help and good luck with everything!
