IGCSE October/November 2026 Study Plan: How to Use the Next 18 Weeks Properly

The Actual Timeline From June to Exam Day

The Cambridge IGCSE October/November 2026 series runs from late October through to late November. Exact exam dates vary by subject and are published on the Cambridge Assessment International Education website, but the window is consistent across years: papers typically begin in the last week of October and run through the third week of November.

From today, June 3, that gives you roughly 18 weeks before the first papers start. Which sounds comfortable. Until you account for what those 18 weeks actually contain.

Weeks 1 to 7: school is still in session in most UAE schools for the next few weeks, followed by summer holidays starting in late June or early July. Summer runs until late August or early September. Then term starts again, and the period from September to October is the busiest few weeks of the school year before exams — assessments, coursework deadlines, and the general chaos of a new year that doesn’t feel like a new year because exams are already close.

The 18 weeks split roughly into three usable phases. Each phase has different objectives, and treating them all as “revision time” is the mistake that produces students who feel like they’ve been working hard since June but arrive at October still shaky on foundational material.

Phase 1 (Weeks 1 to 6, June to mid-July): Foundation and Gap-Finding

The most common mistake in June is starting with past papers. Past papers are essential, but not yet. Doing them in June tells you what you don’t know without giving you the time to do anything about it in a structured way. The right use of Phase 1 is building the foundation and identifying the specific gaps you’ll need to address in Phase 2.

What to do in Phase 1

Go through each subject’s syllabus — the actual Cambridge syllabus document, not just your school textbook — and mark which topics you’re confident on, which you’re shaky on, and which you haven’t properly covered. Be honest about this. A student who marks “confident” next to everything and then scores 60% on their first past paper is just going to repeat that experience in October.

For the shaky topics, go back to the content. Textbook reading is fine at this stage. The goal is understanding, not exam performance. You’re building material to work with in Phases 2 and 3. If you can’t explain a concept in your own words without looking at your notes, you don’t understand it yet — you’ve just memorised the shape of the words.

Keep sessions manageable. Two hours per subject, rotating across subjects across the week, is sustainable. Three subjects a day at two hours each is six hours of focused work. That’s realistic for a motivated student during this phase. More than that, and quality tends to collapse before the session ends.

A note on the Maths / Sciences split

For students sitting Maths and Sciences, Phase 1 is especially important because these subjects are cumulative. A gap in Chapter 3 of IGCSE Chemistry creates problems in Chapter 7. A gap in quadratic equations creates problems in multiple later topics. Getting those foundations solid before Phase 2 is the single thing that most reliably determines whether the rest of the plan works.

Phase 2 (Weeks 7 to 12, mid-July to mid-September): Consolidation and Past Papers Begin

Phase 2 includes the second half of summer and the return to school. It’s the phase where most students lose momentum, because summer holiday and study don’t naturally coexist, and the return to school brings a new set of demands that compete for the same mental bandwidth as revision.

This is also the phase where the gap map from Phase 1 pays off. Instead of revising everything broadly, you’re targeting what you identified as weak, which is significantly more efficient. A student who spends Phase 2 drilling their weak topics rather than re-covering material they already know will arrive at Phase 3 in a much stronger position than one who just worked through the textbook again.

Introducing past papers

Start past papers properly from Week 7 or 8. Not as a test — not yet — but as a teaching tool. Sit a paper, then immediately go through it against the mark scheme. The mark scheme is the key document. Understanding why answers receive marks, specifically what phrasing or content IGCSE examiners reward, is a skill that takes time to develop and that matters enormously in the actual exam.

At this stage, focus on one or two papers per subject per week rather than rushing through as many as possible. Going deep on two papers, reviewing every answer and understanding every mark, is more valuable than doing ten papers and just circling your mistakes.

Managing the summer holiday honestly

Some students will study consistently through summer. Most won’t, or will study for two weeks and then drift. If you know you’re in the second group, build that into the plan now rather than pretending you’re in the first group and feeling bad about it in August.

Two hours of focused study per day, five days a week, across the summer is 200 hours of preparation by September. That’s more than enough to complete a thorough foundation review across six to eight subjects. The problem isn’t that summer is too short. It’s that two hours a day feels negligible in the moment and enormous in aggregate by September.

Phase 3 (Weeks 13 to 18, mid-September to Exam Day): Intensive Revision and Exam Technique

By September, term has started. You have roughly six weeks until the first O/N papers begin. This is the phase most people think of when they think of “revision,” but it only works well if Phases 1 and 2 were done properly. Students who arrive at September with unfixed gaps and no past paper experience will spend this phase in a permanent state of barely-catching-up.

For students who did the work in June, July, and August, Phase 3 is where everything consolidates.

What Phase 3 looks like week by week

Weeks 13 to 15 (roughly September): increase past paper frequency to three or four papers per subject per week. Full papers, timed, under exam conditions. No phone. No breaks except the ones built into the paper. This is the stamina-building phase. Two hours of concentrated exam work is different from two hours of reading notes, and students who haven’t practised under real conditions often find the actual exam more draining than expected.

Weeks 16 and 17 (early to mid-October): pull back to targeted revision of any topics that past papers keep revealing as weak. At this stage you’re not starting anything new. You’re fixing specific recurring gaps. If your Chemistry papers keep losing marks on electrochemistry, that topic needs another pass. If your English essays aren’t earning marks on inference questions, look at exactly what the mark scheme rewards for those.

Week 18 (the week before each paper): light revision, sleep, and logistics. Know your exam dates and times. Know your exam centre. Have your stationery sorted. Don’t cram the day before a paper — the marginal gain from one more evening of notes is far smaller than the cost of walking into an exam tired and wired.

How to Prioritise Subjects Without Abandoning Any of Them

Students sitting eight or nine IGCSEs can’t give all subjects identical attention. The physics of time doesn’t allow it. But abandoning subjects entirely is also a mistake, because IGCSE grades compound — a weak grade in one subject affects your overall picture in ways that matter for A-Level subject choices and university applications.

A sensible prioritisation framework works like this. Divide your subjects into three groups.

The first group: subjects where you’re already reasonably strong and just need to maintain and sharpen. These get two or three sessions per week in Phases 1 and 2, increasing to daily past paper practice in Phase 3. The goal is protection, not transformation.

The second group: subjects where you have clear gaps but the material is teachable and you have time. These get the most intensive Phase 1 and 2 attention. These are your highest-leverage subjects — the ones where focused work now will make the biggest grade difference by October.

The third group: subjects where you’re weakest and the gap feels large. Be realistic about what’s achievable in 18 weeks. You can move meaningfully in 18 weeks, but probably not from a D trajectory to an A. Set a specific, achievable target for these subjects and build a plan around getting there, rather than an aspirational target that leaves you feeling like you’ve failed even if you improved.

How to Actually Use Past Papers Rather Than Just Do Them

Past papers are the most overused and underutilised revision tool at the same time. Students do a lot of them. Most students don’t get nearly as much from them as they could.

The paper itself is data collection. Sitting it tells you what your current level is. The real work is what happens after. A student who sits a paper, marks it, notes the score, and moves on is doing data collection without analysis. The score by itself tells you almost nothing actionable.

What tells you something actionable: looking at each question you lost marks on and asking three things. Did I not know the content? Did I know the content but phrase the answer wrong for the mark scheme? Did I run out of time and not attempt it? Those are three completely different problems requiring three completely different responses. “Do more past papers” addresses none of them specifically.

The mark scheme is as important as the paper itself. Cambridge mark scheme language is very specific. Command words matter. “State” wants a brief factual answer. “Explain” wants a mechanism or process. “Evaluate” wants argument, counter-argument, and a reasoned conclusion. Students who answer “explain” questions with “state”-level answers lose marks regardless of whether the content is correct. Learning to read the question correctly and match the answer format to the command word is a skill, and past paper review is where that skill gets built.

Build in a minimum of 30 minutes of mark-scheme review after every paper. More if any section produced a lot of wrong answers. Less if you were checking work you already know well. The review is not optional. It’s the session.

The Revision Mistakes That Feel Productive But Aren’t

A few specific things that come up consistently and are worth naming.

Re-reading textbooks and notes without active recall. Reading feels like studying. It isn’t, or not efficiently. Information you read passively has a much lower retention rate than information you retrieve from memory. After reading a section, close the book and write down what you remember. That act of retrieval is what embeds the content. Reading again without retrieval is just passing your eyes over familiar words.

Making elaborate notes and colour-coded summaries. Some note-making is useful. The version that takes four hours to produce a beautiful page of colour-coded content, which you then never test yourself on, is four hours of drawing rather than four hours of learning. If you’re spending more time on formatting than on content, something has gone wrong.

Doing past papers without timing yourself. Untimed past papers don’t build the skill that matters most in the actual exam, which is time management under pressure. Always time your papers. When you run out of time and have to leave a question, note that. Time management is a separate exam skill from content knowledge, and it only improves through timed practice.

Studying the subjects you’re already good at because it feels nice. This one is very human and very counterproductive. Sitting with subjects you’re comfortable in feels like progress. It isn’t, or not much. The marginal improvement from spending three hours on a subject you’d already grade yourself a B in is much smaller than the improvement from spending the same three hours on a subject where you’re currently a D. Do the hard thing first.

The Summer Holiday Problem — and How to Handle It

Summer is Phase 1 and the beginning of Phase 2. It’s also the period when the whole plan most commonly falls apart.

The problem isn’t lack of time. Summer has more free hours than any other period in the school year. The problem is the absence of structure. Without school creating a daily rhythm, study sessions that are purely self-generated require a level of discipline that most people, adults included, find difficult to maintain at a high level for two months.

A few things that actually help. Fixed hours, treated as non-negotiable, are more effective than “I’ll study when I feel ready.” The feeling-ready condition rarely occurs on its own. If you’ve decided you study from 9am to 11am every day, that happens before you’ve had time to talk yourself out of it. The specific hours matter less than the consistency.

Shorter, consistent sessions beat occasional marathons. Three hours a day, five days a week, produces 180 hours of summer revision. Two eight-hour days per week — the marathon version — produces 128 hours, requires significantly more willpower, and tends not to sustain itself past week three. The daily habit is the better engine.

Tell someone about your plan. The mild social accountability of having told a parent, sibling, or friend what you’re going to do is genuinely a small but real motivator. Not a replacement for discipline, but a useful addition to it.

And if summer goes badly — if you hit August having done much less than you planned — recalibrate without spiralling. The plan is Phase 1 through Phase 3. If Phase 1 took longer than expected, adjust Phase 2 accordingly. The October/November exams don’t move. Everything else can be adapted.

Putting It Together

Eighteen weeks is a genuinely good amount of time to prepare for IGCSE October/November exams. Students who use it with a clear phase structure, who prioritise their weakest subjects in the foundation phase, who engage seriously with past papers and mark schemes from mid-July, and who arrive at Phase 3 with specific known gaps to close — those students tend to perform at or above their potential.

The students who struggle aren’t usually the ones who lacked ability or even time. They’re the ones who spent June and July in a loose, unfocused way, who treated summer as a break with occasional guilt-driven study sessions, and who arrived at September realising that six weeks before the exam is not enough time to build what wasn’t built in the four months before.

The plan is simple. The discipline to follow it is the hard part. Start now, not because panic is useful but because momentum is. Each day you build the habit of sitting down and working makes the next day marginally easier. That compound effect is what eighteen weeks of consistent preparation actually produces.

Questions Students Ask Most

Key Takeaways

• The IGCSE O/N 2026 exams run from late October through November — there are approximately 18 weeks from today, which splits cleanly into three preparation phases
• Phase 1 (June to mid-July) is for understanding content and mapping gaps — not past papers yet
• Phase 2 (mid-July to mid-September) is for targeted gap-filling and beginning structured past paper practice with mark-scheme review
• Phase 3 (mid-September to exam day) is for intensive timed practice, closing known gaps, and exam technique — not for discovering new gaps
• The revision habits that feel productive but often aren’t: passive re-reading, elaborate note-making without retrieval, untimed past papers, and studying comfortable subjects instead of hard ones
