What's on the P3 to P5 year-end maths paper
The short version
The year-end paper covers the whole year, not just the topics your child studied last term. Most of the marks are not lost on new or difficult material. They go to careless mistakes and half-learned topics that have been there since Term 1. The tables below list every topic your child is tested on, and what goes wrong on each.
Why this paper is harder to revise for
A Weighted Assessment covers a few topics, so revising for one is manageable. You know what is coming and you practise it.
The year-end paper reaches back to Term 1, which your child studied nine months ago, was tested on once, and has not looked at since. There is too much to cover, so most families end up revising whatever is in the current workbook. That is the material your child is least likely to get wrong.
Every topic, and what goes wrong on it
This is the full list for each level, not a selection. Find your child's level and read down it. Telling a child to "revise fractions" is not something they can act on. Telling them what goes wrong in fractions is.
Primary 3
| Topic | What goes wrong |
|---|---|
| Numbers to 10 000 | The smaller digit taken from the larger |
| Division | The remainder left out of the answer |
| Fractions | One quarter called bigger than one third |
| Length, mass and volume | 3 km written as 300 m |
| Time | An hour counted as 100 minutes |
| Area and perimeter | Sides added instead of the space inside |
| Angles | Judged by how long the arms are drawn |
| Parallel lines | Called parallel because they do not touch |
| Bar graphs | A bar read as the lines it reaches |
Primary 4
| Topic | What goes wrong |
|---|---|
| Numbers to 100 000 | A digit confused with its value |
| Four operations | Rounding by chopping off the rest |
| Factors and multiples | HCF used where the question wants LCM |
| Fractions | 1/2 + 1/3 becomes 2/5 |
| Decimals | 0.45 read as bigger than 0.5 |
| Angles | The wrong protractor scale: 60° becomes 120° |
| Rectangles and squares | The wrong pair of sides assumed equal |
| Symmetry | A rectangle's diagonal taken as a fold line |
| Nets | Squares counted instead of folded up mentally |
| Area and perimeter | An L-shape split up for the perimeter |
| Tables and graphs | The nearest number taken, not the crossing |
| Pie charts | A slice taken as the answer |
Primary 5
| Topic | What goes wrong |
|---|---|
| Whole numbers | 5 + 3 × 10 worked left to right |
| Fractions | "Of the remainder" read as of the original |
| Decimals | A dropped place makes it ten times too big |
| Percentage | The decimal moved one place, not two |
| Ratio | The same number added to both sides |
| Rate | A unit left unconverted |
| Patterns | Multiplied by 10 when the rule needs 9 |
| Angles | 180° on a line taken as 360° round a point |
| Triangles | On an isosceles, the leftover not shared |
| Quadrilaterals | An angle copied onto its neighbour |
| Area of a triangle | The slanted side used as the height |
| Volume | Answered in cm² instead of cm³ |
| Solid shapes | Only the cubes you can see get counted |
| Line graphs | The steepest climb read as the highest |
Most of these are careless mistakes rather than gaps in understanding, and that is the good news. They are quick to check, they come back every year, and they are worth more marks than another chapter of new material.
Four weeks out
There is more time than it feels like, as long as it goes to the right topics. In order:
- 1Ask the school what the paper covers. The assessment letter says what is being tested. Most parents read it for the dates and never for the scope, and the scope is the part that tells you what to revise. For how the windows fall across the year: the assessment-window guide
- 2Go through one marked paper together. Not to correct it. To find out why each mark went, because a careless mistake and a topic your child is still learning look identical on a report card and need completely different fixes. how to read a marked paper
- 3Fix the careless mistakes first. A careless mistake is one habit and a handful of questions. A topic your child is still learning needs teaching, and teaching takes time. Doing the quick ones first is what leaves enough time for the slow ones.
- 4Revise Term 1, not Term 4. The latest topics are still fresh. The ones from the start of the year are where the marks hide. This is the most common revision mistake for a year-end paper, and it is the one this format creates.
Three things not to do
Don't buy more assessment books. Volume is not the problem. A child who makes the same conversion mistake across forty questions has practised the mistake forty times.
Don't try to re-teach the whole year. You will run out of weeks somewhere in Term 2, and the topics you never reach will be on the paper.
Don't treat a bad practice paper as a verdict. Four weeks out, a poor result is the most useful thing you will get all term. It is a map of what to fix while there is still time to fix it, and the mark itself counts for nothing.
Where StudyLah fits
Everything above can be done with an old paper and a pen. What is tedious by hand is the part that has to happen every day for four weeks: marking, working out which topic each lost mark belongs to, and keeping track of what is still wrong.
- 1Look at it yourself first. Ten minutes, no account. Three real exam-standard questions, for you rather than your child. You see the walkthrough Lah, the tutor, talks through out loud, with the working appearing on the question as she says it. Try it free
- 2Then register your child, free. The free plan gives them ten questions a day, split across a daily round and a topic drill, plus one full exam paper a month that comes back with an Achievement Level, or a Band for P3 and P4. Start free
- 3Read the mistake book at the end of the week. Every question your child gets wrong, in any mode, is collected there, grouped by topic and sorted into still learning, careless slips and left blank. It is free to read on every plan, and it is the list this guide is about: not the topics that cost most children marks, but the ones costing your child marks.
Every topic in the tables above has its own page, with the mistake worked through and what to say at home. Pick your child's level to see the year term by term. See the syllabus by level

PSLE ready, lah.
Now the practice has to happen.
These guides tell you what usually goes wrong. Your child's own practice tells you what's going wrong for them. StudyLah does the second part, and shows you the answer.
