Profile evaluation Wharton Stanford Columbia R2 please!

Hi!

Profile review please! For Wharton, Stanford and Columbia R2

GRE: 320 160q 160v (do I need to retake / aim for 324?)

GPA: International equivalent to 4.0 for undergrad (business + finance). MS in innovation management (3.7) (Russell Group university)

ECs: Mentoring, college society VPs, student experience committees / college advisory boards, study abroad. All telling a cohesive story about education

International: Female. Black. Citizenship of Caribbean country and European country (both very underrepresented)

Experience: 2 years PMM at FAANG, 3 years of previous experience (5 total). Never promoted but run a side hustle consulting big name clients. Increased salary signficantly (300%) when changing companies. Last job was at a startup working closely with the CEO and I built out a new client offer. Concerned about the lack of promotion. Does it matter? I have a difficult (and bad) manager so I don't think I'll get promo before app. reviews in Jan / Feb. Trying to move teams for promo but it's not guaranteed. 

Goals: I want to go to a ed-tech startup doing StratOps after....and then become a cofounder. This works as my background so far, even at FAANG is in mostly education (comms) / social justice / working with non-profit clients etc. 

Thanks!
