Please change classes before the start of the year. You CAN do this. Five years ago when I was her age that happened to me, only I could not go to a different class since we only had one. Immediately contact the school and inform them of your wish. Bullying makes your "normal" child "weird." It can get REALLY out of hand if she gets some friends against your daughter, at such a great speed that no one will want to stay or become friends/allies with her. Do not wait, that is all I ask. She might act tough, but inside she will be breaking apart.
