Not even giving birth could stop Briana Williams from taking her final exam at Harvard Law School. The class? Family Law, of course. The 24-year-old single mom opened up about the experience after graduating in May. "A lot of times, I didn't think I could do it," Briana told InsideEdition.com. "The reason I kept going is because I didn't give myself an alternative." She says having her daughter Evelyn was the best decision she's ever made.
