Our Science Quiz

Test your knowledge of The Fellowship of Science, science, our universe, and related subjects through a series of open-ended questions. Reading The Book of Science beforehand is recommended, especially for questions about TFOS, but is not required.

When you submit your responses, TFOS will receive, review, and score them. Your results will be sent to the email address you provide.

Prospective TFOSian are encouraged to take the quiz before submitting a Request to Become a TFOSian. Participation is optional, however, and neither completion of the quiz nor the score received is used to determine eligibility for becoming a TFOSian. The quiz is intended as an educational and enjoyable way to explore TFOS and test what you know
