I have 9 hours of school tommorow! help?

Tommorow I have to go into school an hour early because I am struggling in math, but I also have a 2 hour detention because I was late to school the first day back from break, for the 5th time. This is completely absurd, them putting me in a room for 2 hours wont teach me anything it will make me angry at the school and less willing to do what they want me to do. I feel like filing and injunction so that, they dont give me an unnecessary two hour detention. It seems these attendance ladies are doing this out of spite because they are 40 year old woman who sit at a desk all day giving out detention. Any answers that are negative, I will respond to in a unkindly verbal manner. What should I do?
