Harvard University is Jaime Sommers' would-be alma mater. She was accepted there for undergrate studies, but was unable to attend, due to her need to care for her sister, Becca. ("Sisterhood"). Had she matriculated, she would have likely persued a course in literature, likely concentrating on Irish authors such as James Joyce. ("The Education of Jaime Sommers")
It has never been said exactly when she was offered a place at Harvard, Given her stated age of 24 in "Face Off", and the fact that she and her sister seem to have only recently begun living together in "Second Chances", it would seem somewhat unlikely that she received the offer straight out of high school.
