I thought, "If Lindsey was a real person, did she graduate college yet?" After that thought, this post was born. The only reason why I'm only doing GOTYs is because all of the historical dolls would be either out of school/dead if they were real people.
Now, here's the list-
Lindsey- Regardless of when her birthday is, she's out of college. Unless she wants to be a doctor.
Kailey- Same as Lindsey.
Marisol- Since Marisol's book begins on October 22, 2005 (which is a Saturday) and she is in fourth grade, that means she is in 4th grade in the 2005-06 school year. People who were in fourth grade then are in senior year of college in the 2016-17 school year, so that's the same for Marisol.
Jess- Same as Marisol, because her book begins in January 2006.
