No i probably would whether to fit in or mess with the teacher's head.....
elementary school tho, hell no
School would be relaxing if you already knew everything. You would just breeze through the work, get good grades, and open a lot more doors for yourself in the future.
been there, ever felt like you were the only one who knows the subject but you have to hang back and learn together with the others who cant understand division?
its a school where the teachers need to consider the others and pace the teachings and decide that you have already learned everything and advance you to the next class and repeat again.
difficult to have friend there if you keep advancing and then you say to yourself...
wtf am i even doing here? lol
Many schools will let you test out of classes, should you be able to prove proficiency, but when I was in school they never gave me any BS over completing homework before the class ended for the day. Of course, that was some decades ago, and it might be different now.
how much do you think will they teach you in medieval school aside from noble etiquette?
were still talking about medieval school right?(were there even any official schools pre dark plague era?)
Any adult in their right mind reincarnated or not wouldn't even wish to go back to some damned school most especially when that era is so technologically inferior.
