Rate my american accent please?

I think it is about a 7 or 8. Remember that in America there are many different nationalities so if you can speak English fluently then it doesn't really matter. People don't really look at you funny. Within America there are many accents depending on what part of the country you were born too. There is no real "perfect" but I would say you would pass for American if talking on the phone. A few different spots where the pronunciation probably indicates it is your second language such as "q" in a word, but overall very good. Just speaking two languages should be a thing to be proud of
