There is no reason anyone should beat you, a spanking is normal, but beating is not for any reason. think seriously before you decide what to do because what your saying is a serious thing and you could loose your parents or more,but if there really hurting you physically take care of this before its too late and call another family member you can trust first, and decide together what to do don't go through this alone.
Learn some self defense and start working out, that way, if they even touch you, you are prepared to take it like a bitch or just show them that beating you doesn't work anymore. Wewt.
I have been through that. If it's abuse for no reason, then call the cops. If it's abuse for reasons like you getting bad grades, then just do better..
Be careful of the things you say. They could come back to hurt you if people take your words seriously. If you are serious, this isn't the way to handle it. God be with you.
