If you guess incorrectly on a question, you immediately lose the points you "wagered" when setting your confidence level. If you answer the question correctly after that initial incorrect guess, however, you can earn back half of those points in most cases. So, here’s a math question for you: Suppose you set your confidence level at "I think I know it," which means that you’re initially risking 80 points. You guess wrong on the first attempt. How many "second-chance" points will you be able to earn back?
