Jon, I'm a little confused by your narrative.
You said
But thenThe interviewer allowed me to sit in the interview to so he told me to explain my mom that she will get second chance and asked us to study only questions from part 13 of N400 form
Are you saying that your Mom, because of the stress, did prepare for that part as much as she could and wasn't expecting to answer other questions from the agent? Or that she didn't prepare at all?She asked my mom lot of personal questions pertaining to my maternal uncles death and my mom is not a good in english and she barely prepared the part 13 of N 400.
