O-Level G3 Math Paper 1 vs Paper 2: What's Different? (2026)

Compare 2026 O-Level G3 Math Paper 1 and Paper 2: duration, marks, calculator rules and question style, plus what to revise for each.

Quick answer

For 2026 Mathematics 4052, both papers last 2 hours 15 minutes, carry 90 marks each (50%), and allow an approved calculator. Paper 1 has about 26 shorter questions; Paper 2 has 9–10 longer questions and a real-world application.

Paper 1 vs Paper 2 at a glance

How question style, pacing, working, common mistakes and revision differ between Paper 1 and Paper 2
What to comparePaper 1Paper 2
Question styleMany shorter questions across the syllabus.Fewer, longer questions with connected parts; the final question has a real-world application.
PacingKeep a steady rhythm across many separate starts.Budget time across multi-part questions and move on when one part stalls.
Working depthShow enough steps to make the method clear; keep routine work concise.Set out intermediate steps, label quantities, and show how each result follows.
Common mistakesRushing familiar methods, copying a value incorrectly, or missing signs, units and rounding.Losing track of an early value, rounding too soon, or leaving a method unclear.
Best revision approachShort mixed timed sets, followed by a consistent final-line check.One longer question at a time, reviewed from the first step that went wrong.

How to revise for each paper

How to revise for Paper 1

  1. 01Use a short mixed set so the topic is not named for you.
  2. 02Keep a steady pace and mark any question that takes longer than expected.
  3. 03Check signs, copied values, units, rounding and the quantity asked for.

How to revise for Paper 2

  1. 01Read every part and note what each answer needs to represent.
  2. 02Show intermediate steps and carry earlier values carefully.
  3. 03Find the first line that went wrong before retrying the whole question.

Key takeaways

  • Paper 1 needs speed without rushing the final line.
  • Paper 2 needs organised working and early error control.
  • Both papers need targeted review after timed practice.

Worked examples and more about the paper differences

Same syllabus, different pressure

O-Level G3 Math Paper 1 and Paper 2 come from the same 4052 syllabus, but the experience can feel different. Paper 1 has more shorter questions, so small slips and rushing hurt quickly. Paper 2 has longer questions, so one early mistake can affect later parts.

A student should not revise both papers in exactly the same way.

Is Paper 2 harder than Paper 1?

There is no universal answer. Both papers assess overlapping G3 Math skills, but their question structures can make the demand feel different. Paper 2 has fewer, longer questions, so organising several steps and carrying earlier results can feel demanding. Paper 1 has more shorter questions, so pace and accuracy across many starts can be demanding too. Which feels harder depends on the student's strengths and the question.

Original practice examples: short method and connected application

Short-question practice: solve 4(2x − 3) = 20. Expanding gives 8x − 12 = 20, then 8x = 32 and x = 4. Substitute back: 4(8 − 3) = 20. The useful habit is a compact solution followed by a quick substitution check.

Connected application practice: a hall is 8 m by 6 m. Each box of tiles covers 1.5 m² and costs $24. Allow 10% extra area for cutting. The area is 48 m²; including the allowance gives 52.8 m². The box requirement is 52.8 ÷ 1.5 = 35.2, so buy 36 whole boxes, costing 36 × $24 = $864. Rounding down fails the coverage requirement.

A longer question can combine mensuration, percentage and interpretation. Write the units beside each stage and explain why a whole-number decision needs rounding up. These examples practise useful habits; they do not predict which topics will appear in either paper.

How Mentora would split the practice

If Paper 1 mistakes are mostly slips, the next task may be checking and fluency. If Paper 2 mistakes happen at the setup stage, the next task may be method selection or prerequisite repair.

That split matters because both papers can produce the same score for very different reasons.
