Each day, Monday to Thursday there will be one difficult question with an answer in the range 000 – 9999. These are based on the Australian Mathematics competition type questions, so are designed to test your mathematical skills. They will take a while to do and will require pen and paper working

You will need to record your daily answers. On Friday you total up all of the answers and submit it online.

If this total is correct you will get a link to a page where you fill in your name and school. You can then print out your Super Challenge certificate.
