So last night DD was working on her homework from 4:00 to nearly 9:00 (she had a break for dinner of course I made her). AIBU to think this is too much time to be spending on homework. The school told us at the start of the year she'll be getting 2-3 hours with 3 hours being a heavy night when in reality she's had a few times this year when it's been closer to 4. She's a smart student so it's not her struggling it's the amount she's set. I've seen the homework myself and I'm shocked at the quantity. Also it's not exactly major subjects like maths that are adding major bits to the pile. Maths and English are somewhat reasonable. It's subjects like RS and IT both are mandatory in her school which are setting massive massive chunks. She is also getting a lot in science and apparently the teacher doesn't actually teach them the stuff (the missing notes and texts from her usually top scoring friends about frustration help me to believe this).
Is there anything I can do about this I don't want her working 4 hours a day every week day. She needs some downtime as well as time to have a social life outside of school.
