Most students revise IGCSE Physics by rereading notes and highlighting. Research on retrieval practice shows this is the weakest method available, because recognising material is not the same as recalling it. The system below replaces rereading with testing. It fits inside 8 weeks at 4-5 hours per week.
How long does it take to revise IGCSE Physics properly?
Eight weeks at 4-5 hours per week is enough for most students starting from a C/D level. That is roughly 36 hours total, about 6 hours per syllabus topic, since 0625 has six topics. Students aiming to move one grade in under four weeks need closer to 8 hours per week and should prioritise their two weakest topics.
The 0625 syllabus has six topics: Motion, Forces and Energy; Thermal Physics; Waves; Electricity and Magnetism; Nuclear Physics; and Space Physics. They are not equal. Topic 1 and Topic 4 together supply roughly half the marks in most papers. They deserve half your time.
What should a revision session actually look like?
Use a 60-minute block with three fixed parts. First, 10 minutes of recall: write every equation and definition for the topic from memory, then check against your notes. Second, 35 minutes of topic-sorted past-paper questions, done without notes. Third, 15 minutes marking your answers against the official mark scheme and writing each lost mark into an error log.
The error log is the engine of the whole system. Rule one: record the mistake, not the question. “Forgot to convert minutes to seconds” is useful; “got Q3 wrong” is not. Rule two: reread the log before every session. Most students repeat the same five mistakes for months because nothing forces them to look at the pattern.
Sequence the syllabus, do not just “do past papers”
Full past papers come last, not first. Weeks 1-5: revise topic by topic using topic-sorted questions. Weeks 6-7: mixed-topic sections of real papers. Week 8: at least two full papers under timed conditions, 45 minutes for Paper 2 and 1 hour 15 minutes for Paper 4. Our 8-week revision plan lays this out week by week with checkpoints.
Why this order? A full paper diagnoses; it does not teach. If you sit a full paper in week 1, you confirm what you already suspect and burn a scarce resource. Cambridge publishes a limited number of recent 0625 papers, so save the newest two series for timed practice.
Make the equations automatic before anything else
0625 does not give you a full formula sheet, and around 40% of theory-paper marks involve a calculation. If recalling an equation costs you 30 seconds of doubt per question, you lose both time and method marks. Spend the first week drilling the equation list until you can write every Core equation from memory in under ten minutes. Use the complete 0625 equations list and test yourself daily. Five minutes at breakfast beats an hour on Sunday.
“But I understand physics, I just mess up exams.” This is the most common objection we hear, and the error log usually disproves it. When students audit four of their own marked papers, most lost marks trace to three causes: missing or wrong units, no working shown, and misread questions. None of these is a understanding problem. All three vanish with deliberate, repetitive practice. That is exactly what rereading notes never provides.
What if you are stuck below the grade you need?
Self-study works when you can diagnose your own errors. It fails when you keep losing marks and cannot see why. That is the point where 1-to-1 help pays for itself fastest. In our online classes (RM80/hr, 1.5-hour sessions), the tutor builds the error log with the student in the first lesson and targets only the recurring losses. The first hour is a free tutor-led trial lesson, so you can see whether your child is comfortable with the tutor before paying anything.
A weekly checkpoint that keeps you honest
End every week with a 20-mark mini-test built from questions you got wrong earlier. Score below 15 and the topic is not done. Repeat it before moving on. Score 15 or above and move forward, but return the failed questions to the pile for week 8. This single habit separates students who feel ready from students who are ready.
Finally, know your papers. Core candidates sit Papers 1, 3 and 5 or 6, with grades capped at C. Extended candidates sit Papers 2, 4 and 5 or 6, with A* available. Check which tier your school entered you for in January. Revising the wrong tier’s content wastes weeks. The 0625 exam format guide breaks down every paper, its length and its weighting.
