How to relieve stress, I hate my mom?

Sometimes I feel like this, but this by far has been the worst. She always yells at me for not always concentrating my entire mind on school. And when I tell her I try my best anyways for her, she yells at me, smacks me, pulls my hair, and sometimes hits me with a broom, but mostly just threatens. But she gets angry over things that are nothing to be angry about. How can I deal with this? How am I supposed to respond?
