Should I stay or should I go ? (continuation)

I'm tired of school, I'm looking forward to finish school because nowadays, the exercises seem all the same, day by day, therefore, I don't feel like being at school... we have to study things which are not really important, for an example, on a Monday, I was in a maths class and the teacher told us to solve a really hard problem and then, I asked myself " will I need to know this crap in the future? this doesn't make sense... at all. " The person who created the whole school thing should be processed and I'm serious... no one likes school and I'm not an exception.
