She wrote nasty things about me on Twitter?

So, this is my background of her......please read.
So, basically what happened was that I had to correct her test, and she recieved an "F" on it. I wrote some comments such as "messy handwriting" or "bigger drawings" or whatnot. This was a month ago.
I found out today that she had apparently written about it on Twitter.
I decided to look it up and I found them. She wrote like five tweets about it; she was calling me "Bitch" and posted some pictures of her test and saying she wanted to fight me and that she was going to look me up on Twitter and "tag" me (I actually don't have a Twitter).
My school is against bullying, I'm not sure what the policies state, but I can print these tweets out and give them to the office.
What should I do about this? Should I report her or should I talk to her in private about this?

I wouldn't worry about on less she starts bullying you. If she tried to pull anything at school then you could print them out. But I'm not sure if the school can do anything about that. Make sure you have witnesses with you so you have some proof.
