CGP vs Letts Revision Guides: Which Is Better for GCSE 2026?

Every year, somewhere around October half-term, the same question appears in school corridors, WhatsApp group chats, and desperate late-night Google searches: CGP vs Letts revision guides which is better? It is, frankly, the Marmite debate of the British education world. You either swear by CGP’s peculiar brand of cheesy humour and jam-packed pages, or you prefer Letts’ cleaner, more visual layouts. And both camps will defend their choice with the kind of conviction usually reserved for whether a scone gets jam or cream first.

Here’s the honest answer upfront: neither publisher is objectively superior. What makes a revision guide genuinely useful depends almost entirely on how your brain works, how you learn, and — critically — how much time you have left before those exams land. A student who loves reading dense, comprehensive notes will thrive with CGP. Someone who learns visually, needs audio support, or has left revision until April half-term might find Letts/Collins a better fit.

According to Ofqual, the regulator overseeing GCSEs in England, the 9-1 grading system introduced from 2017 has shifted expectations at the top end of the scale — Grade 9 demands demonstrably exceptional performance, not just competence. That raises the stakes considerably when choosing revision materials.

This guide cuts through the noise. We’ve analysed the top products from both publishers currently available on Amazon.co.uk, assessed their strengths for specific subjects and learning styles, and given you a clear framework for deciding which one actually deserves your money in 2026.

Quick Comparison: CGP vs Letts at a Glance

From the table above, one thing is immediately clear: both publishers are closely matched on price and exam board coverage, so those factors alone won’t make the decision for you. The real differentiators are writing style, learning format, and digital extras — which is where things get genuinely interesting. CGP’s RevisionHub gives it a notable edge for students who want a fully integrated digital revision experience, while Letts’ structured time-based formats (such as their “In A Week” series) are a godsend for students who need a clear plan and a ticking clock.

Top 7 GCSE Revision Guides: Expert Analysis

1. CGP GCSE Maths AQA Complete Revision & Practice: Higher — with Online Edition, Videos & Quizzes (for the 2026 and 2027 exams)

The flagship CGP Maths guide for Higher tier students is, to put it plainly, an absolute unit. This Complete Revision & Practice edition combines the full revision guide and exam practice workbook into a single book — which already makes it exceptional value in the £10–£14 range. It covers every Higher tier topic for AQA Maths with CGP’s characteristic no-nonsense clarity, and comes with access to the CGP RevisionHub platform where you’ll find video solutions, online quizzes, and a full digital edition of the book.

What most students underestimate is just how thorough the exam-style questions are. Unlike some publishers who recycle the same three question types, CGP varies the wording to mirror the unpredictability of real exam papers — something that matters enormously once you’re sitting in an examination hall in June. UK reviews consistently rate it as a trusted, comprehensive study companion, with tutors across the country recommending it as a core revision tool.

✅ Genuinely comprehensive Higher tier coverage

✅ Combined guide + practice = excellent value

✅ RevisionHub digital access included

❌ Can feel overwhelming in smaller doses — not ideal if you need concise snapshots

❌ Humour-heavy style won’t suit every learner

Best for: Committed Higher tier students who want one book to rule them all, from initial revision through to mock-exam practice.

2. CGP New GCSE English Language AQA Revision Guide with CGP RevisionHub (for exams from 2026)

The updated 2026 edition is a substantial step up from earlier versions. It covers every reading and writing skill on the AQA specification, includes a full set of practice papers, and — crucially — the RevisionHub digital component now includes graded sample answers. That last detail is surprisingly rare and genuinely valuable: seeing exactly what a Grade 5 answer looks like versus a Grade 8 helps students calibrate their writing in a way that abstract mark schemes simply don’t.

For GCSE English Language, where student progress is notoriously difficult to track (there’s no neat “right answer” to practising analytical writing), having structured sample answers to benchmark against is the kind of practical support that makes a real difference. In the £8–£11 range, it’s also well priced for what’s included.

✅ Updated for 2026 specification changes

✅ Graded sample answers — genuinely unusual and useful

✅ Integrated RevisionHub with exam skills videos

❌ Some students find the written explanation density heavy going for humanities

❌ Companion workbook sold separately

Best for: AQA English Language students who want depth, structure, and a clear model of what examiners are actually looking for.

3. CGP New GCSE Combined Science AQA Higher Revision Guide with CGP RevisionHub

If there’s one subject where having a reliable, accurate revision guide matters most, it’s Science. Specifications change, new content gets added, and an outdated book can actively mislead a student who doesn’t know better. CGP’s updated Combined Science AQA Higher guide — revised for the current specification — covers Biology, Chemistry, and Physics in one volume with CGP’s trademark structured layout and now includes RevisionHub access.

For Combined Science students (the majority of GCSE pupils in England), the challenge is breadth rather than depth. You need confident coverage across three sciences without the luxury of three separate books. This guide handles that well, flagging Higher-only content clearly so Foundation students borrowing it don’t accidentally start revising material they won’t be tested on. UK reviewers frequently note its reliability and accuracy as standout qualities.

✅ All three sciences in one volume — practical and cost-effective

✅ Higher-only content clearly flagged

✅ RevisionHub integration with up-to-date science content

❌ Doesn’t replace Triple Science guides if you’re doing separate qualifications

❌ Jokes feel a little forced in Chemistry pages, if we’re being honest

Best for: Combined Science Higher tier students who want comprehensive, exam-board-accurate coverage without buying three separate books.

4. CGP GCSE History AQA Revision Guide — with Online Edition, Quizzes & Knowledge Organisers (for the 2026 and 2027 exams)

History is the subject where revision guide quality varies most wildly between publishers — because the material is rich, contextual, and highly specific to which topics and exam boards you’re studying. CGP’s AQA History guide earns its reputation by being exhaustively specific rather than vaguely general. The inclusion of knowledge organisers is particularly smart: these condensed visual summaries function brilliantly as final-week flashcard replacements and are the sort of practical addition that students actually use, rather than just nodding at appreciatively and then never opening again. Available in the £8–£12 range on Amazon.co.uk.

✅ Knowledge organisers — rare and genuinely useful

✅ Quizzes and online edition included

✅ Strong AQA specification alignment

❌ Only covers AQA — Edexcel History students need a different edition

❌ The condensed format means some context gets trimmed

Best for: AQA History students who want both comprehensive content notes and quick-access revision tools in the final fortnight before exams.

5. Letts GCSE 9-1 Maths Higher Revision Guide (Letts GCSE 9-1 Revision Success)

And here is where Letts earns its place in the conversation. The Letts GCSE 9-1 Maths Higher Revision Guide (ISBN: 9781844198023, available on Amazon.co.uk in the £6–£9 range) takes a notably different approach from CGP: it’s visually cleaner, with more white space on the page, and organises content into defined revision modules that each take roughly 30–45 minutes to complete. For students who find CGP’s densely packed pages anxiety-inducing — and there are more of them than you’d think — this structure is genuinely liberating.

The Letts guide also supports multiple learning styles more explicitly than CGP does, which research on effective study techniques from the University of Cambridge has consistently highlighted as important for sustained knowledge retention. The layout is more accessible for learners who process information visually rather than through reading dense text.

✅ Clean, uncluttered layout — lower visual noise

✅ Timed revision modules aid planning

✅ Covers AQA, Edexcel, OCR, and WJEC Eduqas

❌ Less comprehensive per page than CGP — some nuances are trimmed

❌ No equivalent to CGP RevisionHub

Best for: Visual learners and students who struggle with information overload, particularly those needing a structured timetable to manage their revision.

6. Collins GCSE 9-1 Maths Higher In A Week: Ideal for the 2026 and 2027 exams

A Collins rebranding of the Letts “In A Week” format, this guide (available on Amazon.co.uk in the £5–£8 range) is built on a brilliant, honest premise: some students genuinely do leave revision until the last week. Rather than judging them for it, this book helps them. Each day covers a focused set of topics, with concise explanations, summary boxes, and quick-test questions that take no longer than 45 minutes per session.

The spec sheet won’t tell you this, but the real strength of this format is psychological. A manageable seven-day plan reduces the paralysis that students feel when staring at 18 months of content. As BBC Bitesize — which millions of UK students use alongside their guides — emphasises, breaking revision into smaller, digestible chunks is one of the most effective strategies for knowledge retention. This book essentially builds that principle into its structure. Works across AQA, Edexcel, OCR, and WJEC Eduqas.

✅ Brilliant for last-minute, structured revision

✅ Daily plans remove the paralysis of open-ended revision

✅ Concise and manageable — no information overload

❌ Not comprehensive enough for students starting from scratch

❌ Best used as a supplement to earlier revision, not a standalone guide

Best for: Students in the final week or two before exams who need a focused, time-bounded plan to consolidate and test knowledge quickly.

7. Letts GCSE Revision Success — AQA GCSE Chemistry Complete Revision & Practice

The Letts Complete Revision & Practice for AQA Chemistry is worth singling out for one reason: it combines revision guide content, exam practice workbook questions, and an audio walkthrough of every topic in a single edition. The audio component — downloadable from the Collins website — is something CGP doesn’t currently offer, and for auditory learners it’s a meaningful differentiator. Listening to a topic summary while making notes, rather than reading it cold, is a well-supported learning strategy. Available on Amazon.co.uk in the approximately £8–£11 range.

Higher-tier content is clearly highlighted throughout, and the magazine-inspired visual pages break up what would otherwise be an overwhelming density of chemical equations and mechanisms. UK buyers note it as particularly effective for students who don’t respond well to CGP’s humour-heavy style.

✅ Audio walkthroughs — unique feature among major publishers

✅ All-in-one guide + practice format

✅ Magazine-style layout reduces cognitive load

❌ AQA-specific — check your exam board before purchasing

❌ Some reviewers note coverage can feel slightly surface-level on harder Higher topics

Best for: Auditory learners and visual learners studying AQA Chemistry who want multi-modal revision support in one book.

How to Get the Most from Your Revision Guide: A Practical Usage Guide

Buying the right guide is only half the job. The other half — the part nobody puts in the blurb — is using it properly.

Don’t read it like a novel. This seems obvious, but it’s the most common mistake. Passive reading produces almost no long-term retention. Instead, read a section, close the book, and attempt to recall the key points from memory. Both CGP and Letts build practice questions into their guides precisely for this purpose — use them. The Education Endowment Foundation, which conducts UK-based research into effective teaching and learning, consistently identifies retrieval practice as one of the highest-impact revision strategies available.

Time your sessions. Letts’ “In A Week” format does this for you. If you’re using a CGP guide, create your own sessions: one double-page spread per 30-minute slot, followed by 10 minutes of self-testing. Short and frequent beats long and infrequent every time.

Use the online extras. CGP’s RevisionHub is included in the price of new books — don’t leave it sitting idle. The graded sample answers and exam skills videos are particularly useful for English Language and History, where mark-scheme thinking is everything. Similarly, Letts/Collins audio walkthroughs (downloadable from collins.co.uk) are free to access with a new book; auditory learners who ignore them are leaving support on the table.

Write in the margins. A revision guide isn’t a precious artefact — it’s a tool. Annotate it, highlight it, add your own mnemonics. The act of engaging physically with the content strengthens memory far better than neat, untouched pages ever will.

Who Should Use What? Real-World UK Student Scenarios

Scenario 1: The Thorough Planner in Leeds, starting revision in January. You’ve got five months, you’re aiming for Grade 8s across the board, and you have the patience for dense content. CGP Complete Revision & Practice editions are your natural home. Buy one per subject, work through them systematically, and supplement with past papers from the exam board websites. The RevisionHub digital extras keep things fresh when the paper format starts to feel relentless.

Scenario 2: The Last-Minute Panic in Bristol, two weeks out from exams. You know, roughly, what you’re supposed to know. You just haven’t looked at it since December. Collins/Letts “In A Week” or “In Two Weeks” guides are specifically engineered for your situation. They won’t build deep mastery, but they’ll consolidate what’s already in your head and give you the structured plan you desperately need right now.

Scenario 3: The Visual Learner in Birmingham who finds CGP overwhelming. CGP’s dense pages are specifically not for you — and that’s perfectly fine. Letts’ magazine-inspired layout, with its generous white space, diagrams, and clearly separated modules, will feel far more navigable. For Science subjects especially, the Letts Complete Revision & Practice editions with their audio support offer a multi-modal approach that suits non-textual learners well.

Scenario 4: The Student Doing Both Core and Humanities GCSEs in Manchester. Buy CGP for Sciences and Maths (the depth and RevisionHub digital support justify the investment), and consider Collins/Letts for History, Geography, or English where the visual and audio formats complement essay-based revision more naturally.

How to Choose a GCSE Revision Guide in the UK: 6 Key Questions

1. What learning style suits you? Honest answer required. If dense text works well, CGP is outstanding. If you need visual variety and audio support, Letts/Collins is the better fit.
2. How much time do you have? More than two months? CGP Complete Revision & Practice editions offer the depth you need. Less than three weeks? Collins “In A Week” and “In Two Weeks” formats are purpose-built for this.
3. Which exam board are you sitting? Both publishers cover AQA, Edexcel, OCR, and WJEC — but always double-check the specific edition matches your specification. Buying an Edexcel CGP guide when you’re sitting AQA is a genuinely costly mistake.
4. Do you want digital support? CGP’s RevisionHub is a clear advantage here — online edition, quizzes, graded sample answers, and exam skills videos, all accessed with the unique code in your new book. Only ever buy new for this reason.
5. Is budget a factor? Both publishers are similarly priced (around £6–£12 on Amazon.co.uk), but if you’re buying multiple subjects, CGP’s Complete Revision & Practice editions — which combine guide and workbook — often represent slightly better value per page.
6. Are you replacing or supplementing? If you have strong class notes and a good teacher, a slim Letts revision guide may be all you need. If your school uses photocopied resources and your teacher moves quickly, CGP’s comprehensive coverage becomes more important.

Common Mistakes When Buying GCSE Revision Guides

Buying the wrong exam board. This happens more often than you’d think — particularly with Science, where AQA, Edexcel, OCR Gateway, and OCR 21st Century all have meaningfully different content. Always cross-reference the guide’s exam board against your school’s specification. When in doubt, ask your teacher. Your school’s website or the exam board’s own site will confirm which specification code you’re following.

Buying second-hand to save money. Tempting, yes. A mistake, usually. Older editions may cover content that’s been removed from current specifications — and for new CGP books specifically, the RevisionHub access code will already have been used. As CGP themselves warn, a second-hand book means you lose all the digital features. Given that a new guide costs around £7–£10 on Amazon.co.uk (with Prime delivery the next day), the saving rarely justifies the risk.

Buying every guide available and using none of them. There is a certain type of GCSE student — and many of us have met one, or been one — who buys six different revision guides for every subject, arranges them beautifully on the desk, and then revises exclusively by staring at the covers. One good guide, used actively, is worth ten guides used passively. According to The Guardian’s coverage of exam pressure and revision habits, one of the most consistent patterns in GCSE underperformance is resource accumulation without structured use.

Ignoring the workbook. The revision guide explains. The workbook tests. You need both. CGP Complete Revision & Practice editions combine them, which is partly why they’re so popular. If you buy a standalone revision guide from either publisher, budget for the matching workbook — or use CGP RevisionHub’s built-in tests as a substitute.

CGP vs Letts: The Honest Verdict on Layout, Humour & Learning Style

Let’s be direct about CGP’s humour, because it divides opinion almost as reliably as the guides’ content coverage. CGP books are famously peppered with groan-worthy puns, cartoon illustrations, and the occasional extended joke that has absolutely no business being in a science textbook. The mnemonic “sedimentary, my dear Watson” — which has floated around Student Room threads for well over a decade — is a fair representative sample.

For many students, this levity is transformative. Revision is stressful, and anything that makes the material feel less like a punishment is neurologically helpful. Humour improves engagement, and engagement improves retention. For others — particularly more anxious students or those who find the jokes patronising — it actively gets in the way of focus. Letts/Collins’ magazine-inspired visual approach is more serious in tone, more spacious on the page, and more explicitly structured. It feels like something you could hand to a nervous student and not have them feel overwhelmed before they’ve read a single page.

Neither approach is wrong. They’re just different — and knowing which one describes your student is, genuinely, the most important factor in this entire decision.

Long-Term Cost & Value for UK Students

Over a full GCSE programme (typically eight to ten subjects), the cost of revision guides adds up quickly. Here’s a realistic breakdown:

• CGP Complete Revision & Practice (combined guide + workbook): approximately £10–£14 per subject × 9 subjects = roughly £90–£126 for a full set
• CGP Revision Guide + separate Workbook: around £7–£10 each × 2 × 9 subjects = roughly £126–£180
• Letts Revision Guide (standard): approximately £6–£9 per subject × 9 subjects = roughly £54–£81
• Collins “In A Week” series: approximately £5–£8 per subject — excellent for targeted top-up revision

The total-cost-of-ownership case for CGP Complete Revision & Practice editions is strong: combining guide and workbook into one book, with RevisionHub digital access included, arguably gives you more revision infrastructure per pound than any comparable Letts equivalent. That said, if you’re supplementing solid school notes with a single publisher, the Letts core range at around £6–£9 per title is excellent value.

Prime members on Amazon.co.uk get free next-day delivery on most of these titles — particularly useful when exam season suddenly feels very close and the Royal Mail’s standard delivery window feels less like a service and more like a gamble.

Frequently Asked Questions

Conclusion: So, CGP vs Letts Revision Guides — Which Is Better?

Here’s the verdict, stated plainly: CGP is the better all-round investment for most GCSE students — particularly those with time, multiple subjects to cover, and the patience for its style. The RevisionHub digital integration, the sheer breadth of subject coverage, and the depth of content make it the closest thing British secondary education has to a Swiss Army knife revision tool. There’s a reason it’s described across UK schools, student forums, and education blogs as the default first choice.

But Letts/Collins is not a lesser product. It is a differently designed product for differently wired students. The “In A Week” series is arguably the most honest piece of revision publishing in Britain — it accepts reality rather than pretending students will spend six months meticulously working through a comprehensive guide. The magazine-inspired layout, multi-learning-style support, and audio extras serve a real audience that CGP simply doesn’t reach.

The smartest approach? Use CGP as your core resource, and Collins/Letts as your targeted top-up tool — particularly when exams are close and you need a structured, time-boxed plan to consolidate what you already know.
