Short answer: serious IGCSE preparation should start at the beginning of Grade 9 (Year 10), when the two-year IGCSE course officially begins. If your child is joining from a different board — CBSE, ICSE, or IB MYP — add a 2–3 month bridging phase before that. And if your child is already in Grade 10 (Year 11) and hasn’t started structured preparation yet, don’t panic: a focused 6–8 month plan built around past papers can still deliver strong grades. Here’s the full grade-by-grade timeline, including what actually moves grades and what wastes time.
First, Understand How IGCSE Is Different
IGCSE (offered mainly by Cambridge and Pearson Edexcel) is a two-year course taken in Grades 9–10 (Years 10–11), ending in external board exams — usually in May/June, with an October/November session also available at many schools. Unlike Indian boards, where marks come largely from recalling taught content, IGCSE exams reward application: interpreting unfamiliar problems, structured working, and analytical writing. This is why students who “know the syllabus” can still underperform — the exam tests how you use knowledge, not just whether you have it. It also means preparation looks different: past papers and mark schemes matter more than re-reading notes.
The Grade-by-Grade Timeline
| Stage | When | What to Focus On |
|---|---|---|
| Bridging (if switching boards) | Grade 8 / summer before Grade 9 | Close syllabus gaps (especially Maths & Sciences); get used to IGCSE question wording and answer structure; strengthen English writing |
| Foundation | Grade 9 (Year 10) | Cover syllabus topics thoroughly as school teaches them; fix weak topics immediately — gaps compound; start topic-wise practice questions, not full papers yet |
| Consolidation | Grade 10 (Year 11), Term 1 | Finish the syllabus; begin past papers topic-wise; learn the mark schemes — how examiners award marks changes how you should answer |
| Exam mode | Final 4–5 months before boards | Full timed past papers (aim for 8–12 per subject); mock exam analysis; target the recurring high-mark topics; exam technique — showing working, command words, time management |
Grade 8: The Bridging Year (Especially If You’re Switching from CBSE or ICSE)
If your child is moving into an IGCSE school for Grade 9, use Grade 8 — or at minimum the summer before Grade 9 — to bridge. The content overlap between CBSE Grade 8 Maths and IGCSE is actually high; the gap is in style. CBSE questions tend to test the method just taught; IGCSE questions embed the method inside an unfamiliar, multi-step problem. Two to three months of working through IGCSE-style questions, with someone correcting the approach (not just the answer), is usually enough. Don’t over-invest here: full coaching in Grade 8 is rarely necessary and can burn a child out before the course even starts.
Grade 9: Where Grades Are Actually Built
Most families treat Grade 9 as a warm-up and Grade 10 as “the real year.” This is the single most expensive mistake in IGCSE preparation. The two-year syllabus is continuous — a Grade 9 gap in algebra becomes a Grade 10 wall in trigonometry, functions, and graphs. The right Grade 9 routine is unglamorous: stay current with school teaching, fix every weak topic within weeks of it appearing, and do topic-wise practice questions regularly. Students who enter Grade 10 with no backlog need only exam training in the final year. Students who enter with a backlog spend Grade 10 re-learning content when they should be practising papers.
Grade 10: Past Papers Are the Whole Game
Once the syllabus is done, grade improvement comes almost entirely from past papers and mark schemes. The mark scheme is the most underused document in IGCSE prep: it shows exactly what earns marks. In Maths, for example, Cambridge awards method marks for correct working shown clearly — even when the final answer is wrong. A student who shows every step will consistently outscore an equally capable student who writes only answers. Aim for 8–12 full timed papers per subject in the final months, and always review errors against the mark scheme, sorting them into three buckets: didn’t know the content, knew it but applied it wrong, or lost marks on technique (working not shown, misread command word, ran out of time). Each bucket has a different fix.
A 2026 Warning for Maths Parents: Check Which Syllabus Your Child Is On
Cambridge IGCSE Mathematics (0580) changed significantly from the 2025 exams onward. Papers 1 (Core) and 2 (Extended) are now non-calculator papers, each worth 50% of the grade — a major shift for students used to reaching for a calculator on everything. A few topics were removed (like linear programming) and new ones added (such as exact trigonometric values, which are required precisely because of the non-calculator paper). Two practical consequences: your child needs deliberate mental-math and manual-calculation practice, and pre-2025 Paper 2 past papers no longer match the current format — useful for content practice, but not for format practice. If a tutor or resource isn’t aware of this change, that’s a red flag.
What Doesn’t Work (Save Your Money and Your Child’s Evenings)
- Endless video lectures: passively watching topic videos feels like studying but doesn’t build exam performance. Practice questions with feedback do.
- Starting too early: starting intensive coaching in Grade 8 for exams in Grade 10 mostly produces burnout, not grades.
- Note-making marathons: beautiful summaries of content the student hasn’t practised applying are decoration, not preparation.
- Spec-blind resources: generic content not aligned to the exact syllabus code (e.g., 0580 vs 0980, Core vs Extended) wastes time on topics that won’t be tested — and misses ones that will.
Frequently Asked Questions
My child is in Grade 10 and we haven’t started. Is it too late?
No. With 6–8 months left, a focused plan works: finish remaining syllabus in 6–8 weeks, then go straight to topic-wise past paper questions, then full timed papers. What you no longer have time for is passive revision — every study hour should involve answering questions.
Should my child take Core or Extended?
Extended keeps all grades (A*–E) and all university doors open; Core caps the maximum grade at C. If your child is borderline, note that schools can usually change the tier entry up to the final exam-entry deadline — so you don’t have to decide on day one of Grade 9. Discuss it with the subject teacher after the first Grade 10 mocks.
How many past papers should my child solve?
For each major subject, roughly 8–12 full timed papers in the final phase, plus topic-wise questions throughout Grade 10. Quality beats quantity: one paper reviewed thoroughly against the mark scheme is worth three papers done and forgotten.
Are IGCSE mocks important?
Very. Mocks are the best predictor of board performance and often feed into predicted grades, which matter for university and sixth-form applications. Treat the first Grade 10 mock as a diagnostic, not a verdict — its real value is showing exactly which topics and which exam habits to fix.
Does my child need a tutor for IGCSE?
Not every child, and not for every subject. A tutor adds the most value in three situations: bridging from another board, a subject where gaps have already built up, and the final exam-technique phase where personalised past-paper feedback makes the biggest difference. For a student who is on top of the syllabus with no backlog, self-study with good past-paper discipline can be enough.
If your child is starting IGCSE, switching from another board, or heading into the final stretch before boards, the difference between a good grade and a great one is usually structured, personal guidance — not more hours. edvi helps students via 1-to-1 online classes to prepare for school admission exams and provides regular tutoring across Cambridge/IGCSE, IB, and other curricula, with tutors who teach to the exact syllabus your child is sitting.
