I'm not in OB, but everything looks pretty good besides the GRE score. You need to do something to retake it and do better. I think the expected value of investment in the GRE is very high for you, but I'm personally very debt averse, so I have a hard time recommending taking on debt to take the test. I bet you can come up with a few hundred dollars to test again and get some different study materials. A study partner would be a great way to do this for cheap. Find someone else that is aiming relatively high and study with them.
What happened? Were you close to your goal on practice tests?
