I want to know the answer to the following question:
In what year did Notre Dame have its earliest undergraduate that was female?
All the background I'm provided with is that "In the mid-1960s Notre Dame and Saint Mary's College developed a co-exchange program whereby several hundred students took classes not offered at their home institution, an arrangement that added undergraduate women to a campus that already had a few women in the graduate schools.". Is that enough to answer the question?
