This is far easier said than done. I've always been a night-owl anyhow, and I particularly had a difficult time staying awake in school as a teenager. To further complicate matters, when I was taking Ritalin, I would crash at specific times during the day; thankfully, my teachers understood this, and the fact that my grades improved drastically allowed them to let it slide. Recent studies have found that, during puberty, people require more sleep in order to function properly - it's not just a matter of what time you go to bed. Scientists simply confirmed what everyone has secretly known all along: puberty is physically stressful on the body. You're growing more, you're under the influence of wacky hormone cocktails, and it makes life difficult all around. Some school districts put this to the test in California by starting the school day at 10:30 am instead of 9:00. The result was overwhelmingly positive: students were paying more attention and were less disruptive in class, and test scores improved significantly. Why this has only been implemented in a handful of schools is beyond me. Perhaps it's the long way around, but it would be of benefit to you and your peers if you took action. I would perform the research, get credible medical professionals in your corner, and find out the proper way to address this issue with the superintendents. You may need petitions, but I wouldn't start there. Build your case first, find the evidence you need, and prepare to answer questions by those who will play devil's advocate or bring opposing arguments. You could even use this as the basis of a paper for class. If you are prepared and your arguments are well-constructed, you might turn the tide and demonstrate to the adults that classroom sleepers aren't lazy slackers who partied too hard the night before. You will not only accomplish something major for yourself but also bring positive change to your classmates.
