Not to depress you, but have you ever thought about the average high school student's day? Seven hours, a short lunch, rushing around from class to class. Tutoring or clubs or practice or games or other things to do after school. Home by dinner time, then homework for like two or three or four hours. Homework assignments on weekends, and even on holiday breaks. It's like having a full time job and a part time job too.
The longer we work and the tired-er we get doing homework, the less we get done and the harder it is to do good work.
Breaks are the answer. The later it gets, the more breaks we need. Try taking 10 or 15 minute breaks every 30 or 45 minutes. It really makes a difference, even though what you probably want to do is just push through and get it over with.
Just make sure you get back to work after the break.
