How was your experience of obtaining citizenship through marriage?

Anyone in here obtain their green card and then citizenship through marriage? How was your experience? After 3 years of having GC, did you just apply and go take the test? Is there another interview? Do I need to keep preparing proof along the way? Any personal experiences, what exactly happened? Thank you in advance.

I just had my citizenship interview last week. I applied after the 3 years with green card, it took 1 year from when I applied till interview date. You just have to know the questions for the test they ask 10 questions out of the 100. You have to pass 6 it's easy. All they asked was for 2018 taxes, green card, ID and passport. The rest were questions that are on the application. It was easy. My oath ceremony is next month.

Failed pretty hard so I filed a VAWA petition.
