How much homework should an 8th grade student get?

I think that an 8th grade student should get a fair amount of homework and classwork. We will be going into High school next year and if we get a low amount of work, we will be surprised and shocked about the amount of work in high school. We will basically get "pounded" with work. I think that we should get a medium amount so that we can be somewhat ready but noy too much because then we will get stressed and overwhemed since we didn't get that much work in 7th Grade.
