When 19-year-old Lesley Wright entered her freshman year at the University of Florida -- Gainesville, she dreamed of being a pediatrician.
But she quickly realized she faced an uphill battle.
"Everyone already had volunteer positions at the local hospital by the time I got to UF, so there weren't any even left when I applied," Wright says. "Chemistry 1 is also a weed-out class, meaning it's extra difficult and meant to determine who is cut out for the pre-med life. I failed first semester."
Wright eventually dropped her health-science major in favor of a degree in public relations.
