Just got back from USCIS. I was in and out in about 20 minutes. The whole process was very smooth. It was honestly a blur, so I can't remember what civics questions I was asked, but the officer started with those, before we moved to the reading and writing part of the test. After this, he reviewed my demographic information and asked me to confirm that I would be prepared to take the oath. After a few clicks on his computer he printed my recommendation for approval and told me to expect notification of oath ceremony in about 4 weeks.
I'm so happy and relieved! I'm incredibly grateful to everyone on this forum and this website for helping me through this process. Good luck to everybody who has their interviews coming up soon!
