I've never been in trouble. I've never had detention or anything. I wasn't a teacher's pet though either.
In middle school, I had this one teacher who would kick me out all the time. He just didn't like me. I could ask a person next to me to borrow a pencil, and he'd kick me out of class. Besides that, I've never been in trouble.
I liked all of my science classes from biology to chemistry. I thought dissecting was one of the most interesting parts of it.
