    Why do you require an email? That's fishy! Why don't you ask for credit card info too? Try to become better people in the future. And don't you Google's captcha service, they track way too much.

      Hi, thanks for giving this a try. If you wish to receive a report on the questions that you got correct/incorrect tnen you will need to enter your email address. However, if you just want to see your score you can enter a dummy email address as suggested.

    Nice quiz, but IMO there's no reason to ask for an email. For future quiz takers: https://10minutemail.com/

      Thanks for your feedback. I understand the reluctance, from some people, to share their email in this context. Even without an email you should be able to complete the quiz and see your result ... so hopefully the quiz is still useful when used in this way. If you are willing to share your email, you will get an email with a link to access the solution, including the questions which you got correct/incorrect. We will also keep you updated when similar content is published. I felt like this was a reasonable quid pro quo, but will definitely be keeping an eye on how this is received by readers. Thanks.

      Hi Michael, thanks for giving it a go. If you enter your email in the form at the end of the quiz you should be emailed a link that will include the solutions, and allow you to review the questions which you got correct/incorrect.
