> He hates homework (as do most kids)

I just didn't do my homework and got bad grades. Luckily in my country you can always get in via standardized tests instead of grades so I did well in life anyway. I'm not sure why homework is weighed so heavily in grades, it mostly just shows how much free time the students are willing to sacrifice. The biggest cost this had for me was the guilt that I hadn't done what I was supposed to do, which made me feel like a bad person, but in hindsight I did much better than most of my more studious peers so it really wasn't all that important.
