Physics is one of the most rewarding IGCSE subjects, but it also has a reputation for being challenging. The good news is that with the right strategy, you can turn physics from a source of stress into one of your strongest grades. This guide breaks down the approach that works for the vast majority of students we have tutored over the years.
Start with the Syllabus, Not the Textbook
Before you open a single textbook, download the official syllabus from your exam board (Edexcel, CIE, or AQA). The syllabus tells you exactly what is examinable. Every topic, every equation, every learning objective is listed there. Use it as a checklist throughout your revision.
One of the most common mistakes students make is spending weeks on a topic that carries very few marks in the actual exam. The syllabus keeps you focused on what the examiners will actually test.
Understand the Topic Breakdown
IGCSE Physics typically covers seven broad areas, regardless of exam board:
- Forces and Motion-- including speed, velocity, acceleration, and Newton's laws
- Electricity -- circuits, resistance, current, and voltage
- Waves -- sound, light, reflection, refraction
- Energy Resources and Transfers -- conservation of energy, efficiency
- Solids, Liquids, and Gases -- particle theory, pressure, gas laws
- Magnetism and Electromagnetism -- fields, motors, transformers
- Radioactivity and Particles -- nuclear decay, half-life, safety
Approximate mark weight by topic (CIE 0625, based on recent papers)
Start your revision with the topics you find hardest. It is tempting to begin with what feels comfortable, but that just delays the difficult work. Tackle electricity and forces early, since these topics carry the most marks and appear on almost every paper.
Why Past Papers Are Non-Negotiable
If there is one piece of advice that experienced physics tutors agree on, it is this: do past papers. Cognitive science research consistently shows that retrieval practice -- actively recalling information under exam-like conditions -- is far more effective than re-reading notes or highlighting textbooks.
Start with papers from the last five years. Do them under timed conditions. Mark them using the official mark scheme. Pay attention to where you lose marks -- those are the topics that need more work.

Watch step-by-step walkthroughs of every question. See exactly how to earn each mark, not just the final answer.

Reading a mark scheme tells you what the correct answer is. Watching a step-by-step video walkthrough tells you how to get there. That is a meaningful difference, especially for multi-mark calculation questions where the working matters as much as the final answer.
At PaperSolve, every past paper is solved on video. You can pause, rewind, and watch the tutor work through each step at your own pace. This is especially useful for topics like circuit calculations and projectile motion, where a single misstep early in the working carries through to the final answer.
Build a Revision Timetable That Actually Works
Cramming the night before does not work for physics. The subject requires understanding, not memorisation. Space your revision over at least 6-8 weeks before your exam, covering 2-3 topics per week.
Here is a sample weekly structure:
- Day 1-2: Review notes and key equations for one topic
- Day 3-4: Attempt past paper questions on that topic
- Day 5: Watch video walkthroughs for any questions you got wrong
- Day 6-7: Move to the next topic and repeat
“Physics went from my son's weakest subject to his second-highest grade. The video walkthroughs made the difference — he could finally see how to set up the calculations.”
Exam Day Tips
On the day of your exam, remember these practical points:
- Read each question twice before writing. Many marks are lost by students who answer a different question than the one being asked.
- Show all working in calculation questions. Even if your final answer is wrong, you can pick up method marks.
- Use the correct units. Forgetting to convert millimetres to metres is one of the most common errors in IGCSE physics.
- If you are stuck on a question, move on and come back later. Time management is a skill that past paper practice develops.
