Sleep.....or not

So it seems like every night i come home completely wiped out after sports practice just to know that i have 3 hours of homework piled up waiting for me in my bag. the way i see it is you can do it until some crazy hour of the night, or you can do what your body wants and go to bed take a failing grade on the homework. We are kids our body NEEDS sleep we grow that way it how our systems work. i'm not saying homework is bad it helps our brain work but when you have six other classes with the same amount of homework we can't handle it... now i need to get good grades in school(thanks to mom) but sleeping is to important not to have.
