It is funny. I once wrote an email to one school at the begining of the month, no any response. Then I had to do sth, which proved to be unnecessary later. And then, I wrote another email to the school and told it that I had mailed sth to them. At the end of the month, this school replied my first email and said "You don't need to mail them to us" . SHIT!!!!! I don't like the school any longer and even hope it refuses me.
Do you mean you submitted the application 20 days after the deadline and it was still accepted? That's not easy. How did you make it?
Yes;
Just emailed to them and explained why you have to delay: business schools ( at least the four i applied) are nice and understanding and i think they would like to attract as many as applicants therefore would give applicants an opportunity to get in the bs~
