How to revise IGCSE Physics: a practical system for notes, questions and feedback
Good IGCSE Physics revision produces evidence that you can use the subject. You should be able to explain why a method applies, perform the calculation and recognise the idea in a different context. A completed notebook or a long list of watched videos does not show that on its own.
The system below works as a repeatable learning cycle rather than a fixed countdown timetable. It links the academy’s free notes, diagnostic tools and practice guidance, while keeping the official syllabus as the coverage checklist. Adjust the time available and level of support to your starting point, school teaching and exam date.
Start with your course, not a generic resource collection
Write down the awarding body, qualification code, exam year and component or unit entry. Cambridge 0625 or 0972, Edexcel linear 4PH1 and Edexcel modular 4XPH1 require different assessment checklists. If you are unsure, use the exam-board finder as a starting aid and confirm the details with your school. Do not infer the route from a friend’s paper or a video title.
Use the current official specification to track topic coverage. Shared physics explanations are helpful across boards, but the required depth and assessment format can differ. Organise resources into a small set: your coverage checklist, reliable topic explanations, suitable questions, matching mark schemes and an error log. A larger collection is useful only when you know when and why to use each item.
Diagnose a skill before deciding what to revise
Begin a topic with a few short questions covering an explanation, a calculation and, where relevant, an experimental decision. Attempt them without notes. Mark both the result and the route you took. The free diagnostic test can help identify a starting point, but a short test is a sample of understanding rather than a prediction of your final grade.
Turn the result into a narrow question. ‘Electricity is weak’ is difficult to act on; ‘I confuse potential difference across parallel branches’ directs you to a particular explanation and circuit diagram. If several topics fail because of units or rearranging equations, work on that shared skill too. A correct guess belongs on the practice list until you can justify it.
Learn the missing idea, then close the explanation
Read the relevant revision note or watch a focused explanation. Use its diagram and worked example to understand the model, the quantities and the conditions under which an equation applies. For example, learn that current is charge passing per unit time before using Q = It. Explain what each symbol means and why seconds and amperes give coulombs.
Then close the explanation and reconstruct it. For an original example, a current of 0.40 A flows for 30 s, so Q = 0.40 × 30 = 12 C. Next reverse the unknown: how long would 18 C take at the same current? The answer is 45 s. If you can calculate only when the question has the original layout, practise identifying the relationship rather than memorising one substitution.
Practise calculations, written reasoning and experimental decisions
Include different ways of using each topic. A circuits session might combine a numerical charge question, an explanation of potential difference and a decision about connecting a voltmeter. A forces session might combine a diagram, resultant-force calculation and interpretation of a motion graph. This reveals whether understanding survives a change in presentation.
Keep practical skills in the routine. Cambridge students should match practice to their entered practical route; Edexcel students should use the practical questions in their own qualification’s assessments. Work on variables, measurement, graphs and evaluation alongside theory. Do not postpone every experimental question until after the content has been revised, because the practical reasoning often depends on understanding that same content.
Mark, repair and return to the skill later
Use the matching official mark scheme after attempting the questions. Identify the first incorrect decision and distinguish missing physics from incomplete wording or calculation errors. If you cannot tell why your answer differs, bring the question and your working to a teacher. Copying a model answer may help you study it, but does not demonstrate that the difficulty has been resolved.
An example week could revisit circuits three times: first diagnose and repair the explanation; next attempt fresh circuit questions alongside an older mechanics topic; later complete a short mixed set and check whether the earlier error returns. Choose spacing that fits your course and available time. The important sequence is independent attempt, feedback and another independent attempt after the solution is no longer immediately in view.
Use full papers and support at the right stage
As coverage becomes more secure, use timed papers to practise selecting methods across topics and managing the whole assessment. Keep some unfamiliar papers for this purpose. Review incomplete answers as well as incorrect ones, and use the resulting evidence to update the next week’s targeted work. A paper score is useful feedback; its meaning depends on the paper, conditions and coverage.
If you repeatedly need help identifying the first step, a structured course can provide explanation, practice and feedback in sequence. Dr Desouky’s IGCSE groups follow the relevant board, with recordings for enrolled students to help them catch up. For an enquiry, bring your course code and one marked attempt. That makes it easier to discuss the right group and the learning support you actually need.
Questions, explained
Choose a question for a direct answer, then explore the explanation and supporting resources. Each answer has its own link to save or share.
Where should I start revising IGCSE Physics?
Confirm your exact course and exam entry, then attempt a short set of questions on a topic you have studied. Use the errors to choose a specific explanation or skill to repair. The revision pathway, topic notes and diagnostic test can help organise that start, but your school’s current specification and feedback should determine the coverage you need.
Should I revise IGCSE Physics with notes or past papers?
Use both for different jobs. Notes and explanations help build or repair understanding; independently attempted questions reveal whether you can apply it. Mark the questions, revisit the missing idea, and retest with a fresh example. Full timed papers become especially useful when enough content is secure to practise choosing methods and managing the assessment as a whole.
How many hours a day should I revise IGCSE Physics?
There is no useful universal number. Your needs depend on current understanding, exam timing, other subjects and the quality of each session. Plan manageable tasks with an observable outcome, such as solving unfamiliar circuit questions and explaining the method. Review the results with your teacher and adjust the time or support when the planned work is not resolving the gaps.
