Was rejected for BA COS/Bio + BS CIS

[Captainrekt000]

Since the change from BSBA-CIS TO BS CIS. It was my understanding that we could double that up with the BA COS. I emailed an advisor to add the BS CIS on top of my BA COS/Bio (double major). She said "I can't add th BS CIS because the dean says you already have your BS Chem from a different school". I thought I could earn 2 TESU bachelor's? The advisor did not specify any reason other than "The dean didn't allow it".
