650 is not even close to cutting it, but ofcourse you can try again. I don't know of anyone getting into those progrs with a GMAT lower than the 95th percentile. Based on your GMAT alone, I'd say no way, but there may be other aspects to your profile you are not divulging. They would pfcourse have to be pretty epic to make up for a 650. It's not bad, it's just not Wharton material.
