ImmCa,I have one question.

I filed my application with bacholor degree and got file number back from bufallo.I acutally finished a master's degree in china before coming to canada.I left china end of school year in suc a hurry that I didn't wait get the certificate.But the school refused to mail it to me.So I filed with bacholor degree.But my score is very tight now.I just heard that my school is willing to give me proof of my master's degree.Should I present to bufallo center or should I not make this complicated?I am afraid they won't believe me,since the certificate says a few years back but I didn't mention it in the application package.you suggestion?thanks!!!
