Find something you want to learn, something you think you could do well in life at. Then use your time to really learn it, and do it. Work with professionals at it if you can. With the rest of the stuff at school, just do your best.
You hate school because you have decided that you don't like it. I loved school. I never missed and it was one of the best times of my life. I wish I could go back. My teachers knew things I did not know yet and I was happy to learn from them.
I think everyone hates school cause it means getting up early and don't boring things in class for like 6 hours. Also because you dont really get any free time away from school besides weekends and brakes. Im in 8th grade and I hate school for all those reasons:(
