She earned her Bachelor of Arts in 1957 with a minor in Fine Arts. At the time of her graduation she hoped to become a social worker. Koo was the first Chinese woman to graduate from Mount Allison. She was part of a wave of Chinese students who attended Mount Allison in the post-war years, and came with her future husband, Benny Lam. Lam also earned a bachelor's degree from Mount Allison University, as well as a master's degree from the University of New Brunswick, and a PhD from McGill University. On September 28, 1957, Lam and Koo married. They lived in Montreal where Lam had a successful career as a scientist and a senior engineer.
