Adjustment of Status - I-485

I moved to the US a couple of years ago on k1 visa. my ex-husband filed my I-485 and I-130. Things didnt work out, he was abusive and we got divorced and he withdraw my petition . I was depressed and didnt know what to do next. I got a call from Immigration asking me to come in.

I consulted with a lawyer and she said i was eligible for VAWA and filed for me,I overstayed in U.S and was preparing my stuff for Vawa during this time DHS called me and took my passport and said I will be having a immigration court because I overstayed in U.S

Now my VAWA case is almost done (EAD received) but I got a letter to go for court hearing next week. It is a Notice of Hearing (master hearing)

I have My Notice Of Hearing next week, what to expect when I go there ? Are they gonna ask me question about my case ? Do I need to take any documents with me ?
