I wouldn't mind a little bit of homework, but an hour or more per class is excessive

One of the pluses of being a working adult is no homework, among other things.

Wait until you're dumb ass is out in the real world. That homework will seem like a fond memory.

My 6yr old has been begging for homework. I finally bought her a workbook and assign her pages to do everyday. Just wait until you get older little girl.

I do think they give kids more homework than they did my generation, at least. I totally get that you want some time to be a kid and have a social life. I am not going to point out that your generation - on the average - spends too much time staring at a smaller version of the idiotbox than I used to have. That's where a lot of your free time goes.
There's a program that you can probably find at the library called, "Where There's a Will, There's An A". It is probably a little old school, but it made my academic life a LOT easier. Maybe it can help you, too.
My last words on the subject: when I was at school, I was mainly competing with other Americans for a place at uni or in the work force; that's no longer true. Because of the internet, we live in a global marketplace. Some accept it and others don't, but the latter group failing to recognize this is going to have a hard life as a wage slave. Think of school as if you were building a fortress of knowledge to face the challenge

*Plays sad violin* I think some schools assign too much homework, but you live your life with deadlines and obligations.

I think having 90 minutes of class is rather nice because we can work in class and ask the teacher directly for help

Your homework as an adult is pretty much just bills, taxes, and the occasional paperwork if you want to get an apartment or a house. If you ask me, it's a lot better than homework. After working my ass off all day, I get to come home, peel my clothes off and go right to bed if I want to. I don't miss school work.

Six hours a day? I had 8, plus homework.

Wait... 6 hours? Not 7 or 8? Wow...

THIS! THIS! THIS!
