Which one is the correct preposition in the following sentence?
My family moved here, when I was in/at highschool.
Thanks
I'll confirm that we'd say "in school."
If you say you're family moved while you were "at school" it sounds like they packed up and left while you were in school that day.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
