The three questions in every PSLE Paper 2 for fourteen years
We are told the PSLE is unpredictable. Yet when we counted fourteen years of Paper 2, three question structures turned up every single time, like clockwork. That is good news, because what repeats can be learned.

Most of what parents hear about the PSLE leans on one word: unpredictable. You cannot know what will come up, so you must prepare your child for anything. I understand the instinct, and there is a grain of truth in it. But it is not the whole truth, and the part it leaves out is genuinely reassuring.
When we built our tagged index of past papers, a pattern surfaced that I find quietly remarkable. Across all fourteen Paper 2s from 2012 to 2025, with no exceptions in the papers we counted, three question structures appeared every single year. Fourteen years, fourteen out of fourteen, for each of the three.
The three that show up like clockwork
These are not three topics chosen by hope. They are what the count shows, drawn from our tagged index of 709 PSLE questions, with the frequency figures here based on the 664 questions from the sat papers (the MOE Specimen paper we keep reported separately). Here are the three structures that turned up in every Paper 2:
- A Geometry question, an angle to chase. A figure where one angle leads to another, and the marks go to the child who tracks the reasoning step by step rather than guessing.
- An Area and Perimeter question, a figure to measure. A composite shape to break into parts, where the work is in seeing the pieces, not in the arithmetic.
- A Volume and Rate question, a tank that fills. A container, a flow, a before and after. The structure is the same each year even as the numbers change.
Geometry
an angle to chase, in every Paper 2 from 2012 to 2025
Area & Perimeter
a composite figure to measure, every single year
Volume & Rate
a tank that fills, without exception in the papers we counted
How often, across the decade
It is not only that each appears once a year. Looked at across the whole stretch, by structure, these three are among the most-tested in the entire paper. Geometry is the most-tested structure of all, at 87 questions across the years. Area and Perimeter is among the most-tested, at 61. Volume and Rate appears 31 times, and crucially, it lands in every Paper 2 we counted.
So when a parent asks me what is "worth" focusing on, I can answer with the count rather than a hunch. These three structures are three of the ten that the PSLE keeps returning to, and they are the ones a child will almost certainly meet on the day.
Why this is good news, not a shortcut
I want to be careful here, because certainty about the past is easy to oversell. I am not saying these will appear next year. I am saying that for fourteen years running, with no exceptions in the papers we counted, they have. That is a statement about what has happened, not a promise about what will.
But it changes how you prepare. A structure that recurs is a structure you can teach to mastery. The skill that matters is not memorising last year's question; it is learning to recognise the structure on sight, an angle to chase, a figure to measure, a tank that fills, and then reaching for the right method calmly. A child who can name what kind of question they are looking at has already won half the battle, because they are no longer staring at a blank page hoping. If you would like to see the full picture, the count lives in our pillar guide on the most-tested PSLE math topics, and you can work through worked solutions at the hardest-questions hub.
Where to start with each one
If you would like to go deeper on the three, we have written a focused guide for each, with worked examples and the common traps to watch for: PSLE geometry questions, PSLE area and perimeter questions, and PSLE volume and rate questions. Start with whichever one rattled your child most in their last paper; the structure is the same every year, so the practice carries forward.
