During her senior year of high school, Williams received a D in her algebra course, preventing her from getting a scholarship to the University of Southern California. She enrolled in Los Angeles City College to retake the course. In 1939, Williams expressed interest in pursuing a degree in physical education in order to teach it one day. To earn money for tuition, Williams worked as a stock girl at the I. Magnin department store, where she also modeled clothing for customers and appeared in newspaper advertisements.
