I have contacted Rotterdam for myself and they said that GMAT score muts be 600 or higher. However, during a GMAT course I took here in Holland, there was a classmate that had been told by the admission board that he could be admitted with a bit lower grade (I don't remember which grade it was, 550 or so) because he had a really interesting profile with more than 8 years of work experience. You don't have so much experience, but perhaps it would be worth it to try, since your GPA looks good.
thanks for replying!
I contacted them as well and as it seems, the score must be higher than 600 (And to be very competitive, I think it should be more than 630). They can only make exceptions in very special cases. Since I'm far away from having 8 years of work experience, I probably won't be a special case. I will retake GMAT in a month from now and hopefully will reach the 600+ zone.
Are you applying for a MSc in Rotterdam as well?
Good luck =)
