I was able to pick up my diploma yesterday. Not completely unsurprisingly, it had a nice big mistake on it. I had been told the university makes a lot of mistakes as far as printing honors on diplomas, so I checked that portion, only to have my eyes move up a bit and see the wrong major listed. Yikes!
Fortunately, they have a fancy-schmancy raised print printer on site, and they printed up a new diploma within a few minutes. Everything looks correct now.
