<p>I’ve gotten more sleep this year, but my junior year was crazy. I was getting 3-5 hours of sleep a night, mostly 3. I think I went kind of nuts last year at school and I could never concentrate. My grades went downhill and I would often study so hard for tests yet still do bad on them. 
This year, I’ve been getting more sleep and even though I’m studying less, I’m getting better grades…:). But I think it really depends on the person, my friend barely sleeps and he’s doing VERY well.</p>
<p>I am living on 3-4 hours of sleep since the school year started…AND its starting to show.</p>
<p>its dangerous if you drive yourself to school and aren’t getting enough sleep. you don’t want to fall asleep behind the wheel!</p>
