GMAT retake advice after 775
Got a 775 after taking the gmat online (90Q/89V/86DI). Took 6 mocks and got a 715, 795 (got a bunch of repeat qs), 775, 755, 795, and a 755.
Personally (and maybe irrationally) feel disappointed with this score. I feel like I could have gotten a 785/795/805
Asian male, big 4 consulting, interesting/decent ish EC, 3.3 UG gpa in engineering, personally think I will have good essays. There is a moderate chance my stats/profile could improve from this baseline. Assuming I'm gunning for H/S/W/Columbia mba/dual degree program- should I retake GMAT to attempt for a 785+? Is there any value in establishing an even stronger gmat score as a spike given the relative average-ness of the rest of my app?
Future interests lie in the research/hf space- I think i have the work ethic and intellect but I feel like I need to establish a better brand/platform
