Looking for a copy of the paper, is there anything anywhere?

Honestly you can't tell. They could do probability again just a different style of question, seeing as 2016 and 2017 last question were from vastly different areas of probability. They literally could ask a hard question on halving the interval (was in my trial once), Pascal's triangle or even...
Both the papers were challenging and orginal in their own ways. Questions such as the milk one in 3u and non-uniform circular which turned into a projectile were both creative and challenging. Thanks again for an amazing day, never gonna forget being humiliated that much!!!!!
