I love the quiz, but you should reduce the horizontal padding so that the quiz isn't so wide. I'm getting a horizontal scrollbar. You might still get it if less padding causes the longer names go from two lines to one, so you may have to use two columns instead of three.
Also, you could use color indicators like red and blue in the Year column to indicate whether it was the Summer or Winter Olympics.
