Should I be a doctor?

I would like to help people medically. I get A's in science and don't hate it, but it's definitely NOT by favorite subject. I hate most things about science, but I liked dissecting A LOT, and genetics, cells, mitosis/meiosis, and stuff like that was easy and not boring for me. My biology teacher this year wasn't that good, so I don't really know if i would like more things or not if i had a good one. Confused.
