What to do when a friend is mad but I still have to go to her house?

So my friend is mad at me and she said she wants a break from me. And well, she really do seems angry and doesn't want to talk to me. And no matter how hard I tried to fix things she doesn't seem to like it. Anyway, we were working on an assignment before we had a fight, and so I need to finish it with her. I ask to go to her place tomorrow and work on the assignment only, she said ok. But it will be very awkward for me because we had a fight but I have to pretend everything it's fine in front of her parents. I don't know if I should hug her when I see her and talk like we normally do or just say hi and simply work on the assignment. I really do want to fix the relationship but I don't think that's what she wants to do, at least not now. So I just want some advice on what to do when I'm over at her place. Like how should I treat her and stuff like that.
