In high school I did near 0 homework. I ended up with a 69 average which rounded up to a 70 allowing me to graduate. I ranked in the bottom 20 students in a class size of around 450 students.
I was a few questions away from a perfect score on my SAT and had an app with over 2 million users so I still got into a good college. So it is doable and I would still encourage others to refuse to do homework.
