School is boring for most people but not all people.
If you're bored of school it's usually because you're not interested in learning about the subjects they are teaching in school.
When I was in elementary and high school it was very boring for me as well but when I went to college for something I was passionate about it was actually pretty fun and I loved showing up to college to learn.
So you're likely hating school and being bored at school it's probably because it's just not interesting to you.
It's also probably because you're forced to be at school and time is dragging on and you can't leave until the school day is over with.
Try finding something in school that you might be interested in such as shop class or something else that they may have if they have those classes.
It seems like school takes forever to be over for good but in reality it passes and soon you'll maybe go to college if you want too or be working at some other job and it will seem like the school part was the easiest part.
