Dorothy Millies had to quit school after the eighth grade and go to work during the Great Depression, but she never gave up her dream of finishing high school.

Years later, when one of her grandchildren dropped out of school, she decided to challenge him — if he graduated, so would she.

So, at the age of 92, she finally got her diploma.

She talked to Growing Bolder about what it was like to study again and do homework 80 years after she did it last.
