DS who is just 7 gets this much homework. 3 subjects every night apart from Wednesdays. One subject he finds harder than the others so always takes a long time. This weekend he has a science project to complete as well. He does do other out of school activities as well and the evenings now are just so long. We still haven't finished the difficult homework from yesterday and haven't even started the science project. Is this an unreasonable amount of homework at his age? We aren't in the UK btw.
