This lesson explains how to allocate time across each IGCSE Physics paper to avoid running out at the end.
The time-per-mark rule
Paper 2/4 (Theory): 80 marks in 75 minutes = about 56 seconds per mark. A 4-mark question deserves roughly 3.5 minutes. A 6-mark extended response question deserves about 5.5 minutes.
Paper 1/3 (Multiple Choice): 40 marks in 45 minutes = about 67 seconds per question. That is just over a minute per question.
Paper 6 (Alternative to Practical): 40 marks in 60 minutes = 1.5 minutes per mark. Graph plotting and data analysis take longer per mark than recording, so budget extra time for graph questions.
Strategy for Paper 2/4
- Read the question and underline key words (20 seconds).
- Write the answer (time proportional to marks).
- Move on immediately when done. Do not polish.
If a question takes more than double the expected time, leave it and return later. The marks at the end of the paper are worth the same as those at the start.
Strategy for Paper 1/3
First pass: go through all 40 questions. Answer every one you can quickly. Mark uncertain ones with a pencil.
Second pass: return to marked questions. Spend remaining time on these.
Never leave a question blank. There is no penalty for guessing.
Strategy for Paper 6
Graph questions are typically worth the most marks and take the most time. If the paper has a graph question worth 8 marks, allocate 12 minutes to it (allowing extra for ruler work and plotting accuracy).
What to do if you run out of time
If 5 minutes remain and you have not started a question, write bullet points instead of full sentences. Show equations and substitutions for calculation questions. Even partial answers earn marks.
Practice under timed conditions
Do at least three full papers under strict time conditions before the exam. Use a stopwatch and do not allow extra time. This builds the pacing instinct you need on exam day.
Need a Plan Based on Actual Work?
A private taught trial can help distinguish whether the repeated difficulty is mainly Physics knowledge, Mathematics, practical reasoning or exam technique before regular lessons are discussed.
