Our family it was done on the dining room table until mid-high school, when the new house was big enough for substantial desks in bedrooms (all rooms held queen sized bed & desks). Study in bedrooms at that level was better for pulling all-nighters & the fact that everybody was studying different things.

I'm at uni and while I have a desk in my study, I still will go and study on the dining room table so I can spread my uni books out.
