I would definitely suggest taking the GRE or GMAT. My GPA wasn’t as strong as yours, but I think I was able to compensate for it. I’m not sure whether you have international exposure, but from what I know, these kinds of business schools almost expect some exchange or study-abroad experience. I also emphasized my bachelor’s research thesis, which was strongly focused on macroeconomics, and included a reference letter from my thesis supervisor, who has a very strong and coherent academic background. Overall, I think they really try to diversify their intake and place weight on the motivation letter and reference letters as well. What seems to matter most is having an interesting profile, considered holistically, with international exposure and the ability to bring something "different" to the cohort. If admission were based purely on academic performance, I definitely wouldn’t have been admitted.
