When Should You Start Revising for Your IGCSEs?

"Am I too late to start revising?" "When should I have started?" "What if I haven't done anything yet?"

If those questions are circling your brain, you're not alone. They're some of the most common worries IGCSE students have as exams creep closer.

Juggling eight or nine subjects, each with its own topics, papers and deadlines is stressful. And when everyone around you seems to have a colour-coded timetable already, the pressure piles on fast.

Don’t worry. This guide breaks down when to start revising for your IGCSEs, what to focus on at each stage, and how to catch up if you feel behind. Read on to find out more.

Key Takeaways

• Start around six months before your exams for the best results. Beginning in October or November of Year 11 gives you time to build understanding gradually and strengthen long-term memory without the panic.

• Year 10 is for building habits, not cramming. Light, regular review after each topic makes Year 11 revision far easier.

• Match your strategy to the stage you're in. Consolidate early, add past paper questions in the middle, and practise full timed papers as exams approach.

• It's never too late to start. Even if you feel behind, focusing on high-yield topics, past papers and active recall can still get you strong results.

When Should You Start Revising for IGCSEs?

IGCSE exams usually begin in late April or May. 

For the summer 2026 series, Cambridge IGCSE papers run from 24 April to 9 June and Edexcel from 7 May to 15 June. Always check your own exam timetable, as dates vary by board, subject and zone.

Work backwards from your first paper, and the timeline becomes clear.

If you're in Year 10

You don't need a full timetable yet. The aim is to build habits gradually.

Reviewing material at the end of each topic will make a huge difference later. Spend 20–30 minutes a week on light consolidation, like making flashcards and summarising your class notes.

By term 2 or 3, start adding short practice questions and quizzes so your memory is tested regularly.

If you're in Year 11

Your timeline has two key milestones:

• Early-stage revision: around six months before exams (October or November). This lets you cover all your topics at a steady pace.

• Mid-stage revision: around three to four months before (January or February). This is when things get more structured, with past papers (opens in a new tab) and active testing.

Start earlier and you can work in shorter, calmer sessions focused on understanding. Start later and you'll lean more heavily on high-priority topics and past papers, which is still a solid plan.

What If You're Behind?

First, breathe. Loads of students feel late to revision, especially after busy terms or mock exams. You can still catch up.

Here's how to do it smartly:

• List your subjects and rank topics by priority. Focus on the ones that come up most often and the ones you find hardest.

• Use efficient active techniques. Think flashcards, blurting, and mind maps rather than passive re-reading.

• Get straight into past papers. They show you exactly what exams expect.

• Be consistent. Even short, focused daily sessions add up fast.

Revision Strategies for Each Stage

Your approach should shift as exams get closer. Here's a simple breakdown of what to prioritise and when:

Two techniques do the heavy lifting at every stage.

• Active recall means testing yourself instead of re-reading notes. 

• Spaced repetition means revisiting topics at growing intervals. 

How to Create an IGCSE Revision Plan

Knowing when to start is half the battle. The other half is having a plan you'll actually stick to.

You don't need anything fancy. A good IGCSE revision plan does four simple things:

• Lists every subject and topic. Use your syllabus or a topic checklist so nothing slips through the cracks.

• Prioritises your weak spots. Give more time to the topics and subjects you find hardest, but keep reviewing your stronger ones so they stay sharp.

• Gets specific. Swap vague slots like "revise Biology" for clear tasks like "10 past paper questions on osmosis." Specific tasks are easier to start and easier to tick off.

• Stays flexible. Review it weekly and adjust as you improve. Build in breaks and at least one day off so you don't burn out.

Why Timing Matters for IGCSE Revision

Your brain forgets faster than you'd think

Revision works best when information moves from your short-term memory into your long-term memory.

The problem is, your brain forgets new material surprisingly quickly. Research on the Ebbinghaus "forgetting curve" (opens in a new tab) shows we can forget new information within 24 hours if we don't review it.

Spacing your revision over months, rather than cramming it into weeks, lets you return to each topic again and again. Every time you do, the memory gets stronger.

This is why starting early matters so much. It gives you the chance to review content actively several times before exams, which makes it far more likely to stick.

The risks of leaving it too late

Putting revision off until the last minute might feel doable at first. It rarely stays that way.

Trying to cover eight or nine subjects in one or two weeks makes it more difficult to do anything thoroughly.

Last-minute revisers also tend to memorise facts rather than truly understand concepts or practise exam skills. Starting earlier helps you stay calm, build confidence and perform better on the day.

Sitting the November IGCSE Series?

Not everyone takes exams in the summer. Some students sit the October/November Cambridge IGCSE series instead, often for resits or specific subjects.

If that's you, the same logic applies, just shifted. Count back six months from your first November paper, and you'll land around April or May to begin early-stage revision.

Frequently Asked Questions

What month should I start revising for IGCSEs in Year 11?

Start early-stage revision in October or November, six months before your first exam. Move into more intensive, structured revision about three to four months before.

Is it too early to start revising in Year 10?

No. Light revision in Year 10 builds strong study habits and reduces stress in Year 11. Even short weekly reviews of your classwork are worthwhile.

Can I still do well if I start revising late?

Yes. By prioritising key topics, using active recall and working through past papers, it's absolutely possible to do well even if you start later than planned.

What's the best way to revise for IGCSEs?

The most effective revision combines active recall, spaced repetition and past papers. Our guide to the best revision techniques walks you through how to use them.
