In Prisoner of Azkaban (I’m rereading the book now so this has been on my mind), Hermione uses time travel to take multiple classes that occur at the same time. I’m wondering how much extra she ages according to the other characters in the book because she is reliving the same time period multiple times. I know on a basic level it’s a simple equation (if she takes three classes at 9AM she is living two extra hours per class compared to her classmates) but there are factors I don’t know due to the fact that I grew up going to public schools in the US not private boarding schools in England.
What I know from the book:
1) She takes 12 classes versus Harry and Ron’s 9 class schedule.
2) Three of these classes occur at the same time.
3) She has a set of three exams that overlap as well as another set of two exams that overlap.
What I don’t know:
Hogwarts is based on a typical UK boarding school so
1) How many days a week do typical classes occur?
2) How long does a typical class last for?
3) What is an expected amount of homework for a class?
I understand every school is different, every teacher gives a different amount of homework, and every student puts a different amount of time and effort into homework and this question is therefore unsolvable BUT I’m hoping people who have taught at or attended a British boarding school can weigh in and come up with some average values to enter into the equating. Can we:
1) Form an algebraic equation with defined variables to figure the answer out.
And
2) Create values that make sense for all these variables based on the unknowns.
Finally, let’s assume for purposes of this equation that she is not also using the time turner to catch up on lost sleep. She is only using it to take additional classes and do additional homework.
