Hi, thanks for your responses. According to GMAT official website my scores are just a bit above average which is 582, q42 and v28. Carnagie Mellon recommends 640 minimum to add weight to the application. Also, I have all the math and programming background they require, however, I come from a university in Colombia that is not globally renowned.
Given this info, what do you think is worse? Applying with a 620 GMAT score or applying without GMAT?
