"There is an atmosphere at the university of elitism," Shanley added.
She said she had been ridiculed.
"My accent has changed so much since starting at uni because I was getting comments if I said a word like 'canny'. They liked to point it out."
She also said tutors would ask Scottish students to repeat themselves or to speak more clearly.
"Accent bias is one of the biggest issues. And they made assumptions from our accents on our intelligence levels and whether we would be friends or not," she said.
A University of Edinburgh spokesman said: "We are incredibly proud of our diverse community and work hard to create an environment that eliminates discrimination and allows all of our students to have the best experience possible during their studies.
"Our Dignity and Respect policy sets out clear expectations of behaviour, including recognising when comments or behaviour may be harmful or upsetting to others and acting accordingly.
"We have a well-established equality, diversity and inclusion committee which brings together staff and student representatives from across the university to provide oversight on our progress around EDI activities.
"After listening to students, we have also introduced and continue to evolve a new support model that provides more dedicated pastoral and academic guidance throughout their studies."
