So for me, if I don't get enough sleep, I'm fucking done. If you just can't focus, try getting a bit more sleep. I find that about 9.5 hours of sleep is just the right amount of sleep for me, but it could be different for you. Eating in the morning also seems to help. However if other things are distracting you like checking your phone constantly or that one girl who always wears yoga pants and happens to bend over in front of you that's another story. Try the previously mentioned 50 minutes of work = 10 minute break. The girl? Tap that in the bathroom, continue on with your day. If all else fails, try a bit of coffee, maybe a cup before school or bring a decent sized thermos of it and sip throughout the day. Don't over do it or you'll fuck yourself out of sleep.
