First of all talk to your mom, not when she is mad at you either. Stat by saying I wanted to talk about ways that we can get along better. You don't want to back her into a corner where she feels defensive. Tell her you feel that since you haven't had any drug issues or trust issues you are ready for a little more responsibility. Then give her simple examples like a later bed time or some extra time with your friends. Point out that you will be honest with her and keep her in the loop if anything seems to be too much for you or out of the norm.

Next tell her you think she is doing a good job loving you and you know that you can be stressful but you want to devise a plan that will help you learn when you are out of line other than physical tactics and that you promise to listen when she uses these new tacts and think about your actions.

Also tell her that you would like the chance to earn some of the nice things that you want. Maybe if you can ask her if you keep your agreements with her on the punishments and responsibilities if she'd be willing to spend a little money on some of these things you'd like. 

Honey goes a lot farther than vinegar. Remember though that what she is doing is not necessarily right and that if you can get her to agree to all those things and you keep up your end of the bargain and it doesn't get better you may all need family counseling. she does need to be fair.

The school counselors are there for you. They can help address these issues and can help set you all up with family counseling if need be. But try the relaxed more adult approach first. I say this because if it does work she will likely have a much more positive view toward you and you may find that she reverses the equilibrium of her scales.
