Yesss I’m British too so it’s weird sending my teens to what feel like an American high school.
I really wish the did a High school years EP part 2 - (call it secondary cause it’s 2nd) and they could do a British focus.
They should make it fully customisable where you can have a new school lot type… yes they should bring primary school in too!! …. Then if you had a new school lot type you could select it to be primary or secondary and chose which students went to the school and the teachers.
They should make it fully customisable where you have a school planner section in the calendar and make a full timetable for your sims, choose the teacher and the students and the subject. Same for after school clubs.
You should be able to have parent teacher meetings and have more things your teens can get in trouble for that they would have to go to detention for.
