Add up all the time you spent doing homework. What would you say: a million billion hours? Roughly a trillion bazillion hours doing homework, over the course of your life? Well, as it turns out, it was a complete waste of your time:

Research reveals primary school homework offers no real benefit - and only limited results in junior high school.

Only senior students in Years 11 and 12 benefit from after-school work, associate professor Richard Walker said.

"What the research shows is that, in countries where they spend more time on homework, the achievement results are lower," Dr Walker, from Sydney University's Education Faculty, said.

Okay, but, why does so much homework get assigned? "At the moment homework (is often) an add-on because parents want it," says Dr. Walker. Haha.
