Why Students Run Out of Time on Paper 4
Paper 4 is 150 minutes and carries 130 marks. That is approximately 1.15 minutes per mark — meaning a 10-mark question should take roughly 11–12 minutes.
Most students who run out of time do not have a speed problem. They have a prioritisation problem. They spend too long on early questions and have insufficient time for later ones — where many high-value marks are available.
Common Time Wasting Patterns
Over-working question 1 and 2 — early questions are typically easier and shorter. Spending 20 minutes on the first 2 questions (which may only carry 8–10 marks combined) leaves insufficient time for later 10–12 mark questions.
Getting stuck on one part — spending 8 minutes on a single part (b) that is worth 2 marks while a later 6-mark question goes unattempted.
Re-doing calculations repeatedly — checking and re-checking a calculation that looks wrong (when it may be correct) wastes 5–10 minutes over a paper.
The 1 Minute Per Mark Rule
A simple guide: spend approximately 1.1–1.2 minutes per mark. Track time loosely:
- 10 marks done → approximately 11–12 minutes used
- 50 marks done → approximately 55–60 minutes used
- 100 marks done → approximately 110–115 minutes used
If you are significantly over this pace at any checkpoint, consciously speed up for the next question.
The Move-On Rule
If you are stuck on a single part of a question for more than 3 minutes without progress, write what you know, mark the question, and move on. Return to it in the last 10 minutes if time allows.
3 minutes stuck earns 0 marks. Moving on often earns 2–4 marks elsewhere.
Using the Final 15 Minutes
Leave 15 minutes at the end of Paper 4 for:
- Returning to skipped/incomplete questions
- Checking answers on questions where you felt uncertain
- Verifying units and rounding on key answers
Students who finish Paper 4 with 15 minutes remaining and use it productively typically recover 3–8 additional marks.
Building This Habit Through Practice
Time management is a habit, not just a strategy. It must be practised in timed conditions repeatedly. Students who sit 5+ full timed Paper 4s before the exam develop instinctive pacing; students who have never timed themselves often have no instinct for when they are running behind.
