Between your spelling and your lack of punctuation, it was very hard to understand what you are saying. Translated into English, what I gather from your post is that your performance group instructor had you do a new routine in front of her beginners class with no warning. She wasn't happy with it, buried her face in her hands, and yelled at you in front of the class.
If that's what happened, I'd say let it go. She's probably learned her lesson that it wasn't a great idea. She was probably embarrassed about it. If she doesn't mention it again and doesn't try it again, it won't be a problem. If she does bring it up in your performance class, then I think you can say something to the effect that it wasn't really fair to expect you to perform a new routine with no notice. Or if you have such bad feelings about it that it's interfering with your ability to learn from her, then speak to her privately.
