Adjustment of Status - I-485

So today was my interview...8am..I was called in first and went through a gruelling experience. Nerves got the best of me and i messed up a few questions. Like which school my husband's son attend. I told him I didn't remember the name. I also didn't remember my husband's supervisor name. I gave him all my joint documents he kept them. My husband also messed up a few questions like the month I moved in. He said September, I said December. December is correct anyway. The officer was very serious and didn't smile at all. I now leave it in God's hands. He said he was satisfied with the interview and we will hear from him in 30 days.
