Public high schools run about eight hours and middle schools about six or seven and a half (I'm not a middle school student). Obviously hours could be extended. But for what purpose? As for school being "cooler" that depends on your opinion of school. It depends on your dedication to school. You also have to define what cooler means to you. Does cooler mean better learning environment? Does it mean better teachers? I'm curious to see how you define "cooler" before I go any further.
So I take it instead of actually debating about your topic you're going to give up. How do you expect to win a debate if you don't have an argument to present to the contender. That is so counter intuitive. I mean, literally this website is called debate.org and instead of actually presenting a debate you give up before the debate even begins.. Makes no sense at all.
