Students have been told they must take their final exam in the nude or fail.
Associate Professor Ricardo Dominguez - who will also be naked in the exam room - looks after the visual arts class in UC San Diego and says that these exam conditions have been the same for the past 11 years.
He claimed everyone knows the deal from start of term and those who don't like the idea of being naked for their final exam simply shouldn't take the subject.
One parent is protesting over the rule and told ABC 10: "It bothers me, I'm not sending her to school for this. To blanket say you must be naked in order to pass my class. It makes me sick to my stomach."
