I'm going to skip school for 2 days to  go to the beach
I get bored at school.
I'm tired of studying all the time.
It sounds like you're just a little burned out. It's against the rules to skip school without a valid reason. You could get suspended.
My parents will cover for me and they can't do anything if I disobey them.
I understand if you feel burnt out but you shouldn't skip school. A good education will help you a lot in life.
