Madonna attended St. Frederick's and St. Andrew's Elementary Schools, and then West Middle School. There she was known for her high GPA, and achieved notoriety for her "unusual" behavior—particularly a kind of an underwear fetish. Madonna would perform cartwheels and handstands in the hallways between classes, dangle by her knees from the monkey bars during recess, and pull up her skirt during class—all so that the boys could see her briefs.
