Ask an MBA Admissions Consultant

I would imagine this question has been addressed before, however, I still would like to ask how much of an effect on the type of undergraduate school one attended has on their MBA application. I have heard expert opinions going both ways.

Having completed my undergraduate studies at a medium sized state school (probably not too well known out of the region), would I ever have to justify why I did not go to larger, more renowned university? I mean if the general consensus is that it matters more of what you made of your experience, I guess I am not too concerned given my background, but occassionally I when I read consultants responses here I get the impression this is not necessarily the case per se.
