How to find out if someone REALLY graduated with MAGNA *** LAUDE?

i know someone who just keeps on bragging about how they graduated with a magna *** laude. Funny thing is that he/she doesn't put this info oh his/her linkdin, fb or anywhere else. im getting a bit suspicious,im particularly interested cause i just enrolled myself into a grad school and i have to listen to his/her over and over how the subjects he/she selected were better than mine or that the school he/she went to is way better than mine. i know the year he/she graduated and the name of school. is there any place i can find the list of honor students of W.P. Carey School of Business (ASU) class of 2006. im not planning to rub that in his/her face, if i find out the truth i will feel better cause right now i feel really pressured. thanks everyone!
