Stuff yourself with food in the morning before school, dont eat at school, use eating time to work, when everyone is eating beat them to the library so it isnt as crowded, when a teacher is boring focus on work you want to be doing. When you get home stuff yourself again and start working , hard, on what you missed out while you were ignoring the teacher and maybe one day you will become superior to your school. Killing yourself is also an option but it is the weak way out. Fire also works
