Supplemental Application to CCS at UCSB!

Okay so when I applied to UCSB I put Art as my alternate major and it says I need to send in a supplemental by today and to be honest Im regretting it because I dont want to have my alternate major in art anymore. I’d rather minor in it. Anyways they say the priority deadline is today and I really dont want to turn it in. Is it bad if I do not submit the supplemental app. Will they be harder on my regular application for not filling out something that I originally wanted to do? Lastly is there even a way I can opt out of my alternate major? Thanks! :slight_smile:
