student teacher relationship

i get along with most of my teachers. but when i am in a class with a teacher i dont like i dont turn any of the assignments in or do any of the homework. if i could have teachers that i got along with then my grades would be way better then they are right now. like my 5th grade teacher. she was a big jerk and i hated her class but as soon as i switched into a different class my grades got way better.
