A clear, week-by-week plan for turning Edexcel International A-Level and IGCSE past papers into a higher grade — what to do, in what order, and how to find the marks you keep missing.
If you only change one thing about your revision, make it this: do more past papers, and do them properly. For Edexcel International A-Level (IAL) and International GCSE (IGCSE), the exam is the most honest guide to the exam. Textbooks tell you what could be asked; past papers tell you what actually gets asked, how it's worded, and how marks are awarded. This guide is the exact plan we'd give a student aiming for an A or A*.
Start by being honest about where you are. Pick a recent paper for your subject — say an Edexcel IAL Biology unit or an IGCSE Maths paper — and sit it under full exam conditions: timed, no notes, no phone. It will feel uncomfortable, and that discomfort is the point. A timed paper reproduces the real pressure and exposes the gap between 'I understand this' and 'I can do this in 90 minutes against the clock'. That gap is where your grade lives.
Next, mark it ruthlessly against the official mark scheme. Every Edexcel paper is published with its mark scheme, and the mark scheme is not a suggestion — it is the rulebook the examiner uses. Do not give yourself 'half marks for trying'. Award only what the scheme awards, and write down every mark you lost and the precise reason you lost it. Most students discover their problem isn't knowledge at all; it's method marks, units, or not answering the actual command word ('explain' vs 'describe' vs 'evaluate').
Then read the examiner's report. This is the most underused free resource in the whole system. After every session, Edexcel publishes a report explaining exactly where candidates went wrong and what the top answers did differently. Reading the examiner's report for the paper you just sat is like getting the answers to next year's mistakes in advance. SuperExam keeps the question paper, mark scheme and examiner report together for every paper, so you can run this loop in one place.
Now the part that actually raises your grade: for each mark you dropped, find the method — not the answer. Anyone can read a worked solution and nod along. The skill is being able to reproduce the steps on a fresh question. Use worked solutions and an AI tutor to understand the 'how', then close the page and redo the question from scratch. If you can't, you haven't learned it yet.
Space it out. A few days after a paper, redo only the questions you got wrong — not the whole paper, just your weak spots. This is spaced repetition applied to exam technique, and it is dramatically more efficient than re-reading notes. Your brain remembers what it had to effortfully reconstruct, not what it passively reviewed.
A realistic weekly rhythm in the final stretch: two full papers a week per subject, each followed by honest marking, the examiner's report, and a method-fixing session; then one 'redo your weak questions' session mid-week. That's roughly three focused sessions per subject, per week — enough to see a clear upward trend without burning out.
Track the trend, not the single score. One bad paper means nothing; the direction over five or six papers means everything. Watch your score climb toward the grade boundary for each session (remember an A* is rarely a fixed 90% — boundaries move with paper difficulty). When you can sit any paper in a unit and land comfortably above the boundary, you're ready.
The papers themselves are free. On SuperExam you can browse every Edexcel IAL and IGCSE question paper, mark scheme and examiner report by subject, and unlock step-by-step worked solutions and an AI tutor when you want the method explained. Pick your subject, pick a paper, and start the loop today — that single habit, repeated, is what separates the students who hope for an A* from the ones who get it.
