To complicate things, I also have committments in part of June that really can't be avoided. As a result, I won't really have time in June to study the GMAT. I told AdCom that I was more than willing to take the GMAT again in mid-late July, but I believe my timing doesn't fit into the WL's timing. Adcom specifically told me to wait.
Theoretically I could absolutely demolish everything and study for 2-3 hours per day, 7 days a week, for the next 2-3 weeks, and then take the GMAT the first week of July, but I would be even more unsure of my ability to increase my score. I do not think going from 680 - 700 would be really material. At that point, with 2 attempts, I think I would need a 720+ to really stick out. That is anything but a certainty...
On a side note, I totally see how people get OCD about visiting this site now!
