Hello,
I think you should be ok with 152 in quantitative reasoning. It is not a selling point, but it does not disqualify you.
It will also depend on your statement of intent and your GPA. The backgrounds of the MGA candidates are quite diverse and what matter is what you expect to learn at Munk School. So I advise you to polish your statement of intent. If your specific interests in international affairs are backed by your academic strengths, a score between 150-152 in Q. should not really hold you back. Moreover, you seem to have a strong GPA and Verbal score.
Good luck to join us in the program.
