Hi Robin! I was looking at the ages of Deepdean girls and started wondering: would they have graduated at age 17?
If girls enter 1st form at age 11, and turn 12 while there, then…
2nd form is age 12, going on 13
3rd form is 13-14
4th form is 14-15
5th form is 15-16
6th form (Big Girls) is 16-17
And since Big Girls are the oldest students at the school, do Deepdeanites graduate at 17? If so, was this typical of girls’ schools at the time? If not, have I misunderstood the Deepdean age groups?
You have not misunderstood Deepdean age groups at all, but you are missing a crucial bit of knowledge that I never wrote down in the books: there are two years of being a Big Girl. It’s essentially modern Sixth Form, but I was hand waving that a little because I knew it was a more modern concept.
So, basically, you would be a Big Girl for your final two years of school, from 16 to 18.
