How can I sharpen my trivia IQ for xbox 1 vs 100 game?

When it comes to trivia, how do you learn the information. Xbox's 1 vs 100 game is so fun. I spend hours playing, but I never get anywhere with it. I have no clue about most of the questions asked. There are players on there that get every single question right at lighting speed. How can I sharpen my trivia skills. Is there a place that I can obtain general trivia knowledge to become a more challenging player?
