I am planning to apply for MBA programs to start next year. I have started studying for the GMAT but it is not clear what score I should be aiming for. As my first practice test, I scored 620. I did slightly better in the quantitative portion.

Now I understand that I need to look at average GMAT scores, but I also realize that as an applicant from China I may need a higher score than the average. I am targeting Oxford and Cambridge. Here is my background:

Chinese female, 28
MSc in Global Politics from LSE
5 years total work experience in logistics and procurement for a global NGO
Volunteer experience includes some pro-bono logistics consulting for nonprofit organizations (about 1 year total) and some community service
