That's easy. All you do is click on my account. When that screen comes up click on "Q&A". When that screen comes up click on "Your Answers". All the questions that you have answered will appear on pages. There are 15 answers per page, so for example if you have 4 whole pages of answered questions then you have answered 60 questions. If you have 4 whole pages plus the next partial page has 6 questions answered on it then you have answered 66 questions so far. By doing it this way you don't have to count every single question that you answered to get your grand total.
