When submitting an art portfolio, what do you think is the lowest gpa/sat score UVA will accept for admission?

To be honest, I don't know the average cut-off but I am answering to confirm your rumor. UVA has admitted students with lower credentials if they are outstanding artists. I was in an advanced art cl where 2 average students(think B/B+ at highest) were admitted. I would definantlyapply regardless of your grades if its your dream school.
