People can vote for their choice on the magazine's Web site, http://www.stuffmagazine.com.
Each month, the magazine features a different contestant that readers can vote for. The winner will receive a $4,999 scholarship.
Wingler said she sent her pictures to the magazine last January. She was the featured contestant for April.
"I read about the contest in the magazine," Wingler said. "The main reason I entered was for the money. I couldn't afford to go to (UNC) if I didn't because the tuition seems to be hiked up every other week."
But Wingler said she does not think she is like the typical girls who enter these contests. "I really don't look that good physically," she said with a laugh. "Those were just really good pictures."
Wingler added that she doubts her parents would approve of her participation in the contest. "My father is a Southern Baptist deacon and my mom is a Sunday school teacher, so we tried to keep (the contest) quiet," she said. "I think my mother knows, but she hasn't seen the pictures."
Wingler said she has an advantage over the other finalists because of her intelligence. She said she was valedictorian of her high school, and made a perfect score on the verbal portion of the SAT.
"The rest of the girls are 24-year-old, community college students," she said.
But Wingler said the competition is tough. "They're all tan, with big, fake breasts," she said. "There's not a whole lot I can do to compete with these girls. Maybe if there was a SAT competition, I could win."
