A maths test in New Zealand is causing a lot of controversy because many students felt it was too hard. The story is getting huge coverage in New Zealand and even in some British and American news outlets. In this video I share one of "impossible" questions and explain how I would solve it. I'm curious if you think this is too difficult for 15 year old students.

*I expedited production of this video to be timely and ultimately got a foot stuck in my mouth! Around 4:10 I should have said "1 metre." Plus I said "1 feet" which anyway should have been "1 foot."

Update 6 April 2018: They uploaded an exemplar answer script 2017 – Excellence. See the file available at:

I did a video about the kite problem from the exam:
