Almost every student “does past papers,” yet only some get a grade improvement out of them. The difference is method. A past paper isn’t a test to pass — it’s a diagnostic that tells you exactly what to fix next. Used that way, it’s the most powerful revision tool in IGCSE Maths.
Start Topic-by-Topic, Then Go Full
Early in revision, work through past-paper questions grouped by topic — it targets specific weaknesses efficiently. Only once topics are reasonably solid should you switch to full papers under timed conditions, which build the stamina and pacing the real exam demands.
Mark Strictly Against the Scheme
This is where most students fall short. Mark your own work strictly to the official mark scheme — counting method marks, not just final answers. The goal isn’t a score to feel good about; it’s an honest map of which marks you earned and which you dropped, and why.
Keep an Error Log
Every mistake goes in an error log with its cause: “forgot to rationalise,” “wrong trig ratio,” “rounded too early.” Review the log before each session. Most students lose marks to the same five to ten recurring errors — fixing those is the fastest route to a higher grade.
Redo, Don’t Just Read
A question you got wrong isn’t learned until you can do it again unprompted, days later. Redoing beats re-reading every time.
Time It Right
Start full timed papers at least six weeks out, so exam pace feels familiar rather than alarming.
