Citizenship

I have been on this forum for months watching every boody 's case and see their experiences wich very useful for my whole process while I was waiting on the line .infact the forum is a very very important tool for people that have immigration cases going on. Other people experience help you understand your process better
Is my whole story

I was granted conditional resident on September 26 2016 and after 2 years i will have to file to remove the condition on my green card. Which I did on 1 years and 9 months before the green card expired this is how the whole process went through.

06 26 2018 I filled the I751
07 03 2018 uscis receive my application
O7 13 2018 receive I receive the I797C which is extended my conditional resident for 18 months
After that I had never heard anything from uscis for months
11 26 2018 I had received a letter tha say they will use my previous fingerprint that was captured no need for any other biometric, then on
05 29 2019 I received a biometric appointment letter wich was code 5 type
06 10 2019 I attended my biometric appointment

After my fingerprint taken everything went calm again, until
After 2 years and 9 months being an LPR I'm able to apply for citizenship because I was granted my green card through my wife who is a US citizen
I file my my N400 paper filled while my I751 is pending, I filled with a copy of the I797 I was received when I filled the I751 and a copy of the expired 2 years green card
I wrote a nice cover letter with my application where I asked to combine the N400 with the already pending I751 I could have a combo interview they would adjudicated together
06 26 2019 N400 filled (paper filled)
07 12 2019 I have received an other 797 C biometric appointment (code 5 type) again
07 24 2019 biometric appointment attended
The same 07 24 2019 I received a letter that said my I751 had been transferred from CSC to NBC where the N400 is processing
09 17 2019 N400 had been selected for an interview
11 06 2019 I attended my interview

I went to the interview with my wife and our 3 year 9 month old son, go with him was not mandatory because the interview was at 7:40 we wouldn't have enough time to get him to daycare then go to the interview but we come to realize go with him was the best choice my wife and I did anyway , is why
When they call me for interview the IO saw My wife and I together with our son sit in the lobby she asked. Is this little fellow outside with your wife your son together ? I respond yes then she replied ok your wife don't have to come she can stay with your son outside
Then she went straight to the I751 just asked a few questions in confirm a few stuff like your adress and I forgot to ad my daughter's name wich was born before I met my wife on the I751 she correct it and added it , then she said the I751 can wait now let's go with your N400
She starts asking me the questions . But before we started I made a mistake on the N400 before I swear to tell the truth I asked her to correct wich she said no problem we will go to that after

To be honest i forget the questions I was being asked but I remember I answer all af them correctly
Except for the reading and writing part which was who lives in the white house she asked me to read and the president lives in the white house I wrote for writing
Then start asking me the yes an no the questions
After the test, she gave me a paper that says your N400 is approves
Then she said go wait in the lobby because I have to ask someone godhead and take out the condition on your green card before I can give you an ceremony appointment letter for next week because we have one coming up
After 20 minutes sitdown someone call my name gave me the paper and said congratulations Sir your citizenship ceremony is
