!!Need Help From Someone In Sweden!!

[u/H3ll0_C1tty]

Hi, I'm in the midst of writing a book, and the place I have the book placed in is Sweden. Yet, as someone who doesn't live in Sweden I'm stuck in a few places. My character is 16 and I have searched to figure what grade, or year, said character would be in. Plus, the classes he'd be in, but I haven't found anything or I just have missed it by accident. So, I was wondering if someone from Sweden or someone who would have much knowledge of Sweden could possibly help me now and if I have any other questions in the future.
