Hopefully, this gives a brief overview of where I stand. I know my GMAT is low, especially for UCLA which is why I may skip that application. My thought was though my academic standing is on the low end of applicants, with some good essays I'd have a decent chance of getting in or waitlisted in round one. Should I strive for a better GMAT (e.g., 620+) and wait for round 2? Any advice would be greatly appreciated. thanks!
