Sorry if this is going off topic of what the thread was about, but I only read the original post.
My daughter (DD14) in 9th grade varies from no homework (though this is rare now), to 3 or 4 hours. I don't have any problem with it. She's going from waking up at 6:00 to get to school by 7:00, and then get home more around 5:00. Since she needs to wake up early, that gives her about until 10:00 to do homework (she does like getting a solid 8 hours, though last year she would stay up until 12:00 a lot of nights, so this is an improvement). That means that she has homework until 8:00 or 9:00 a lot of nights. This gives her, an hour of free time on those nights. I actually think this amount of homework is great, because she has become more responsible and she likes to be busy. I also think this prepares them for in college when the course load might be greater.
Of course, some parents might disagree. Maybe it is too much homework, I don't really know. I just generally think it's good to have a good amount of stuff to be busy with.
