Homework is at the discretion of the teacher, and is also highly correlated to subject. For example, math might be every day, history once a week or so, and a couple gym class health assignments the whole year. But it seems to have nothing to do with what grade you're in. I thought that writing assignments would gradually get longer, but my final essay senior year was half the length of my 7th grade science report on the human body, so I was clearly mistaken.

I always thought the whole sleeping at school thing was pretty lame. I can't say I haven't nodded off a few times, but it seems disrespectful to your teacher and peers. Although, it is a pretty funny break from material when the teacher creatively awakens or badgers the offender. (Or, best of all, let's them sleep through to the next period and awake to utter confusion.)

"I thought that writing assignments would gradually get longer, but my final essay senior year was half the length of my 7th grade science report on the human body, so I was clearly mistaken."

I remember my college freshman year class where every writing assignment could not exceed a single page. The professor's explanation: "You have spent several years learning how to put more things into your writing. Now you will learn to take things out." It was a very important lesson in writing concisely.

Not that this reflects your case, but it reminded me of this and thought I'd share.
