Cambridge IGCSE October/November 2026 timetable — note that in Chemistry the theory paper comes before the practical paper.

Where IGCSE Chemistry marks actually go missing

From marking hundreds of Paper 4 and Paper 6 scripts — the same five leaks every session, and what the plan below does about each one.

1 · The mole

Moles ↔ mass ↔ volume ↔ concentration. Students know the formulae but lose the 3-mark chain on the second step.

Week 2 — every calculation type drilled, then re-drilled in Week 7
2 · Electrolysis & redox

Which ion goes where, the half-equations, and "explain" questions answered with a description instead of a reason.

Week 3 — electrode rules as a one-page map + half-equation practice
3 · Organic naming & reactions

Mixing up alkanes/alkenes, forgetting the functional-group test, drawing displayed formulae wrongly.

Week 5 — homologous series table, reactions in one sheet
4 · Tests for ions and gases

Paper 6 gives these marks away — only if the table is memorised word-for-word.

Week 6 — flashcards + the full table tested every day
5 · Paper 6 technique

Reading burettes, writing "to make it a fair test" instead of naming the variable, graph lines of best fit.

Weeks 6–7 — three timed Paper 6s marked like an examiner
Bonus · Command words

"State", "describe", "explain", "suggest" each pay differently. Write the wrong type and the mark is gone.

Built into every model answer in the solved papers

Seven weeks to Paper 4: the week-by-week Chemistry plan

Seven weeks for 60 lessons? As revision, yes. Topics you already score on: watch at 1.5× and go straight to the quiz. Topics that bled marks in June — usually the mole, electrolysis and organic — get the full lesson, the notes and every past-paper question on them. The last two weeks are papers only.

Retaking Chemistry after June — or sitting it for the first time in November?

Same syllabus, same papers, same grade descriptors as June. The only thing that changes is how you revise.

If June's Chemistry grade wasn't yours…

  • You understood the chemistry but lost marks on calculations, equations and "explain" questions
  • Paper 6 felt unpredictable — apparatus, readings, variables, conclusions
  • You revised from the textbook and the bare mark scheme, never from model answers
  • You need a day-by-day structure for the next seven weeks, not another pile of notes

If this is your first Chemistry sitting…

  • Your school rushed or skipped topics (organic and electrolysis are the usual victims)
  • You're a private or home-schooled candidate and want a teacher who answers on WhatsApp
  • You want the 2026–2028 syllabus taught the way Paper 4 asks it
  • You want the past papers solved step by step — not just the answer line

Three facts for November Chemistry retakers

Results for the Oct/Nov 2026 series are published on 14 January 2027 — in time for most sixth-form and university deadlines.

Nothing new to learn Oct/Nov 2026 examines the same Cambridge 2026–2028 syllabus (0620 A*–G / 0971 9–1; identical content). You're improving answers, not starting over.
Entry closes 21 September Retake entries for a June 2026 subject close on 21 Sep 2026 with late fees. Speak to your exams officer this week; private candidates enter via the British Council or a registered centre.

Chemistry in November — the questions we get asked

How much maths is there in IGCSE Chemistry Paper 4, and can I fix it in seven weeks?

Typically 15–25% of Paper 4 is calculation: moles, concentration, gas volumes, percentage yield, energy changes, rates from graphs. Seven weeks is plenty if you practise daily — Week 2 teaches every type and Week 7 re-drills them in timed papers. Most students find it is the method , not the maths, that was missing.

Do I really have to memorise the tests for ions and gases?

Yes — word for word, including the observations. They appear in Paper 4 and especially Paper 6 almost every session and are the cheapest marks on the paper. The course gives you the full table as flashcards and tests it every day from Week 6.

Is the October/November Chemistry paper harder than June?

No. Same syllabus, same structure, same grade descriptors. Thresholds move a few marks each session because the cohort is different — not because the paper is set harder. Prepare exactly as for June.

I'm retaking after June 2026 — is anything different in November?

Nothing in the content: both sessions examine the Cambridge 2026–2028 syllabus (0620 / 0971, identical content, different grading scale). Entry for a retake closes on 21 September 2026. What changes is your technique — the course teaches you to write what the mark scheme rewards.

What if I end up sitting in June 2027 instead?

Your access lasts two years from purchase, so the same course — and the same WhatsApp support — carries you into June 2027 at no extra cost.

Unsure whether to retake Chemistry in November?

Send Mr. Hosni your June grade, your paper marks and your target — you'll get an honest, personal recommendation within the day.

Paper 4 is on 12 October. Week 1 starts tonight.
