It does help to play all the Global Challenge trivia games. There you have to answer 15 questions, so answering 10 is that much easier. Many questions are repeats. Sometimes I'll merely look at the answers first and know the correct one.
For me the hardest quizzes are the ones with the easiest questions. I take WAY too much time making doubly sure I get the right answer checked.
I say well done to evryone who is willing to play. Everybody adds to the fun and the challenge. I have learned a ton of stuff by doing the trivia and thank Rindy (or maybe curse him

) for getting me into it all!
