I agree with what Jared Goudsmit says in "Sitting in sixth hour" when he says "in sixth period, [...] where our only goal is to learn things I already know" because I feel the same way about the fact that there are some subjects that are unesscesary to keep on learning because we already know a lot of the content we are being taught over and over again. Also when he writes "lunch just happened and [...] we'er full and sleepy," I interpret that as him kind of saying that sixth hour isn't needed because they're so sleepy or maybe suggesting that sixth hour become a nap hour which would rejuvenate students to pay more attention. 

Thank you Jared Goudsmit for pointing out sixth hour and how unneeded it really is to students.
