School is the most interesting place to be. You will realize this when you pass out. Show your interest in every subjects, read textbooks and try to answer every question your teacher ask.
Let me tell you, In college whatever you're going to study would be 80% of your schooling, so once your basics are clear your college would be fine.
To make school a happy place you should do following things:
1. Find a middle way in breaking rules and not getting caught. To find a middle way you gotta run your mind and play politics, Which is sort of interesting and will develop your mind.
2. Show off whenever you get chance, Participate in curricular activities, play sports, Quizzes, etc.
3. The most important thing is to earn respect in teacher's eyes. Merely getting good grades would not make your personality smart & adorable you've to be versatile, learn the art of influence.
4. Homework: Don't get irritated by homework. Now a days internet would give everything related to education. It doesn't means you should copy and paste, instead of that learn conceptually and apply to your homework.
