IGCSE Physics 0625 — March 2023 Past Papers, Topics & Exam Tips
The Cambridge IGCSE Physics (0625) March 2023 session consisted of 6 papers, covering 15 syllabus topics across all papers. This page links to every question paper, mark scheme, grade threshold and session feedback document released by Cambridge for this session, together with a topic-level breakdown of what was tested and topic-matched exam tips in our own voice.
Topic coverage in March 2023
Marks in this session were weighted unevenly across the 15 syllabus topics, with the heaviest emphasis on Kinetic particle model of matter. Substantial weight also fell on Physical quantities and measurement techniques and Energy, work and power , with Electrical quantities and Electric circuits rounding out the five most-tested areas. Together these five topics made up well over half of the topic-level marks awarded in the March 2023 session — a useful signal for where to focus revision time. The full topic-by-paper breakdown is further down the page.
Exam tips for topics in March 2023
- → Kinetic particle model of matter: Whenever explaining kinetic theory, specifically talk about the motion of particles and how momentum changes.
- → Physical quantities and measurement techniques: The main technique for setting up the experiment is being as close to perpendicular to the surface as possible.
- → Energy, work and power: Master the energy conservation principle and rehearse the transformation of energy between GPE and KE as an object falls.
- → Electrical quantities: Memorize Lenz's law: the induced e.m.f. resists the change in magnetic flux that caused it.
- → Electric circuits: A closed switch makes a complete circuit, allowing current to flow; an open switch breaks the circuit, stopping the flow.

0625 Study Tips & FAQ
What are paper variants?
Cambridge releases multiple variants of each paper (e.g., Paper 11, 12, 13) to accommodate different time zones around the world and maintain exam security.
- Variant 1 (e.g., 11, 21): Usually for Zone 1 (Americas)
- Variant 2 (e.g., 12, 22): Usually for Zone 2 (Europe, Africa)
- Variant 3 (e.g., 13, 23): Usually for Zone 3 (Asia, Oceania)
All variants cover the same syllabus and have similar difficulty. Practice with any variant to prepare effectively for your exam.
How to use Mark Schemes effectively
Mark schemes show exactly how examiners award marks for each question. Understanding them helps you write answers that earn full marks.
Example from a Physics mark scheme:
Mark scheme answer:
• speed = distance / time [1 mark for formula]
• speed = 150 / 5 = 30 m/s [1 mark for correct answer with unit]
Tips:
- Look for key words that must appear in your answer
- Note how many points are needed for each mark
- Check if units are required for the final mark
- Understand the difference between "state" (brief) and "explain" (detailed)
Understanding Grade Thresholds
Grade thresholds show the minimum marks needed for each grade. They vary each session based on paper difficulty — harder papers have lower thresholds.
Example Grade Thresholds (out of 100 total):
* Actual thresholds vary by subject and session
How to use thresholds:
- Set realistic target marks based on your goal grade
- Track your practice paper scores against thresholds
- Remember: you don't need 100% for an A* — aim for consistency
- Compare thresholds across sessions to gauge difficulty trends
How is the topic breakdown calculated?
The "Topics Breakdown by Paper" section above shows which syllabus topics are tested in each paper and how many marks they carry. Here's how we calculate this:
Our methodology:
- Extract questions: We analyze each question paper (QP) and identify individual questions and their mark allocations (shown in square brackets, e.g., [3]).
- Match to syllabus: Each question is matched to the official Cambridge 0625 syllabus topics based on keywords, concepts, and question content.
- Sum marks per topic: For each paper, we add up the marks for all questions testing the same topic. For example, if Q1 (4 marks) and Q5b (3 marks) both test "Enzymes", that topic shows as "7 marks" for that paper.
Example: If Paper 3 shows "Photosynthesis - 13 marks", it means questions worth a total of 13 marks (out of the paper's 80 marks) tested the Photosynthesis topic from the Plant Nutrition unit of the syllabus.
How to use this: Look at the paper(s) you'll be taking (e.g., Papers 2, 4, 6 for Extended tier). The topics with the highest marks in YOUR papers are where you should focus your revision. A topic worth 15 marks deserves more study time than one worth 3 marks.
Note: Our topic matching may be inaccurate for questions that span multiple topics. Use this as a guide alongside the official syllabus.
