How would you act around a teacher if you felt like they disliked you, but you still want to pass the class?

I have a teacher that obviously doesn’t like me for any particular reason. I realize that this happens a lot (with people who aren’t just your teachers), but I have to pass this class to graduate and I am not a suck up, so I’m not sure how to act in order to pass it. Maybe it doesn’t matter how I act? What would you do? Have you experienced this before?
