How Many Past Papers Should You Do for IGCSE? (Real Numbers)
It's one of the most-asked questions in every IGCSE forum, every year: "How many past papers should I actually do?" — and the usual answers ("as many as possible!", "all of them!") are useless for planning. Here's a real answer with real numbers: how many papers per subject, in what order, over what timeline — and the one rule that makes five papers outperform fifteen.
- The working benchmark: 5–10 complete, timed, marked papers per subject — fewer done properly beats more done sloppily.
- A paper you don't mark against the scheme is half a paper. Marking + fixing the dropped marks is where the grade moves.
- Work newest backwards: recent papers match the current syllabus; papers older than ~5 years risk testing content that's changed.
- Start topic-by-topic early, switch to full timed papers in the final 6–8 weeks, roughly one per subject per week rising to 2–3 near the exam.
- Stop counting papers; start counting your distance above the grade boundary. Consistently 10+ marks clear = ready.
The honest numbers
| Your situation | Complete papers per subject | Plus |
|---|---|---|
| Comfortable pass target | ~5, timed & marked | Topic questions on your red areas |
| A/A* target | 8–10+ | Mark-scheme fluency: know why each mark exists |
| Resit in 8–10 weeks | 6–8, front-loaded on the failed paper type | Re-do the exact question types that broke you |
| Two weeks to go | As many as fit at ~1/day per priority subject | Mark same-day, re-test the dropped marks next day |
Why these numbers work: by paper 3–4 in a subject you've seen every question format the examiners use; by paper 6–8 you've seen most of the recurring themes (the data across our library shows how concentrated they are — see the most-tested breakdowns for Maths, Physics, Chemistry and Biology). Beyond ~10, returns diminish sharply — if you've been marking honestly. If you haven't, no quantity saves you.
The sequence that works
- Early (months out): topic questions, open bookPractise by topic as you revise each one — untimed at first, mark schemes open. This is learning, not testing.
- Middle (6–8 weeks out): full papers, timed, weeklyOne complete paper per subject per week, strict time, no notes — then the marking loop. This is where the timetable's Saturday slot goes.
- Late (final fortnight): papers ARE the planRising to 2–3 per priority subject per week (or ~1/day in the last days), always marked, always with the fix-list re-tested.
- Throughout: track boundary distance, not paper countPlot each marked score against the grade boundary you need. The trend line answers "am I doing enough?" better than any target number.
Which papers to pick
- Newest first, working backwards — the most recent series match today's syllabus and question style exactly.
- Mind the ~5-year horizon: syllabuses get revised; a 2017 paper may test removed content or use retired formats. Older papers are fine for extra practice on stable topics — just check against the current syllabus.
- Cover all paper types: if your subject has multiple components (core/extended, theory/ATP/practical-alternative), your 5–10 must include each type you'll sit — grades die on the neglected paper.
- Both boards ≠ interchangeable: practise your own board's papers; Cambridge 0580 and Edexcel Maths are cousins, not twins.
FAQ
How many past papers should I do for IGCSE?
Is doing past papers the best revision for IGCSE?
How old is too old for an IGCSE past paper?
Should I repeat past papers I've already done?
So: five to ten per subject, newest first, strictly timed, marked the same day, dropped marks diagnosed and re-tested — while you watch your distance above the boundary grow. The students who ask "how many papers" are usually asking "when can I feel safe?" That number isn't a paper count. It's the week your marked scores sit ten clear of the grade you need.
