Adjustment of Status - I-485

Hi everyone. I had my interview last week on feb 22 at 2:30 at boston office. My IO was beautiful women. My IO was not a friendly but not rude as well. It was saperete interview. First called my USC wife asked 45-50 questions to her after 30 mint. Called to me and same questions asked to me. Just 1 question was mismatch (actually we both give the right answer but give different answer. Question was where your wife’s father do job? My wife said in rastaurant and i said at gas station. Actually her dad go to rastaurant in morning and go to gas station in evening as part time job on cash.so we gave right answers but different answers) rest the interview was good. In the end IO said if we need any additional information we will send you notice in mail otherwise you will get your Green Card in mail. What it mean? I’m anxious.no any updates and online status is stuck on “Interview is scheduled”. I’m anxious. Please reply me if anyone have knowledge,experince or same situation.

Thanks
