Thank you! Only one part was written. They asked me "who was the first president" and I had to write down the answer on a little tablet. All other questions were verbal, I didn't have to write anything down.
I had my interview today in Boston. It was pretty straight forward. They asked me 6 of the easier questions from the civics knowledge test. They didn't ask for any documents other than my passport and green card. I passed the interview and my oath ceremony is scheduled for March 6.
