I always found it an interesting challenge for students to try and predict the year related question that almost always appears.

Here is the 2025 Junior Maths Challenge question.
What do you think will be in the 2026 paper?

I thought the controversy was over using Venn Diagrams in this way - with repeated prime factors used as different elements.
My preference was always Trees simply because it seems easier in this format for students to check their own work. The structure is the working and short cuts are possible.
