A while back, I had a conversation with my american LD boyfriend in which he explained to me how it wasn't uncommon for students at his high school to stay up late to study for tests and complete homework, which is more in line with what I experienced during my school years here in Italy and less like the impression I had gotten from pop culture and past interactions with americans other than my boyfriend.
Edit: I feel like Italian media on the other hand tends to depict high school in a more gritty manner, focusing on the negative experiences of the characters, so I was wondering why and how US media differs in this regard.
