With thanks to eagle-eyed quizzers, errors have been spotted in five of the questions.
A full list of errata is on the page where the quiz was first posted. I will continue to update this if others are discovered.
With just over 20 days to go, happy solving!
How do we submit answers? The quiz says “email me”, but I don’t know your email address, and the contact form on your website doesn’t seem to accept attachments.
We have now resolved this! But for others with the same question, message me through the contact form and I will send you my email address. 🙂
