I don't think PHD requires w/e, but it does require high GMAT and good research background. In fact, the acceptance rate of good PHD programs is much lower than that of good MBA programs because the top PHD programs only admit very few students each year. Sometimes, they even don't admit any one at all.
Thank you very much for your reply. And what do you think of my case? GMAT 640(BAD); I will take the TOEFL test next month; my major in the university was management; now i am in connecticut in usa. i want to apply MSF in BC. Is there any chance to get the offer?
