In Christmas Eve we find out that Maggie came home from her first semester of school with a GPA 'above 4.0'... Maggie is in Elementary School (my math says 5th grade).
GPA is out of 4, the highest you can get is 4, straight A's is a 4.0.
In Highschool if you take AP courses you get +1 point per AP course (so an A is 5.0) making it possible for a HIGH SCHOOL student to get higher than a 4.0. A Junior High School student would need to take a high school level AP course to get higher than a 4.0, an Elementary School student would not be able to get a 4.0. Period.
Goof? or did Maggie skip grades? (Skipping grades (three of them?) AND taking AP classes and getting straight A's and doing all that after immigrating from South America to Chicago and growing up without parents and...)
This is just a mistake by Butcher right?
