Now that you've tested your confidence level once, take a few minutes to answer these ten questions to see how well you apply lessons from the first challenge.
For each question, provide a low and high guess such that you are 90% sure the correct answer falls between the two. Your challenge is to be neither too narrow (overconfident) nor too wide (underconfident). We'll tell you whether your score suggests you're too overconfident.
After the first quiz, you’ll have the opportunity to take another quiz to see if you can improve your score.
