I’ve put a full Ai Tong 2025 P6 Prelim Maths paper online for free, with every question fully worked through step by step (not
just final answers). There’s also a quick 10-question sample you can try with no signup:

Why online instead of a photocopied set: it marks instantly, and every answer has the actual working — so when your child gets
something wrong you can see where they went off, not just that they did.

I also have the other 2025 top-school prelim papers (Methodist Girls’, ACS Junior, Catholic High, Henry Park, Raffles Girls, Tao
Nan, Nan Hua) available on the site at a small per-paper price — but the Ai Tong one is genuinely free, take it as-is if that’s
all you need.

Happy to answer any questions in the comments.
