The papers are done. The 2026 GCSE and A-Level exam season officially wrapped at the end of June, and up and down the country there's a familiar sight: stacks of revision guides being shoved to the back of the shelf, never to be opened again.
Here's the thing most people miss. The few weeks right after exams are the single best window of the year for revision guides — whether you're trying to buy them cheaply for next year or sell the ones you've finished with. Prices are soft, supply is high, and almost nobody's thinking about it.
At Revision Lab we spend a lot of time tracking this stuff. Here's the practical playbook.
If you're buying for next year: don't pay full price
New revision guides from the big names — CGP, Collins, Pearson REVISE, Letts — barely ever go on a real discount. The publishers keep prices tight, so whether you walk into WHSmith (now trading as TGJones on the high street), browse The Works, or check Amazon, a new CGP guide costs roughly the same everywhere: around £6–7 for a single-subject revision guide and £11–13 for a "Complete Revision & Practice" book.
So if you're buying new, the only real saving is a voucher code or a multibuy. A few worth knowing:
- The Works regularly runs multibuy book deals (often "3 for £6" or "4 for £10") that can bring educational titles well under cover price. Worth checking in store and online.
- TGJones / WHSmith rotate book voucher codes — there's frequently an "extra 10% off books" code floating around. Stack it on their sale section.
- Don't overlook the publisher's own site. CGP Books occasionally bundles a guide + workbook for less than buying them separately.
But here's the smarter move…
The best-value revision guides are second-hand — and right now they're everywhere
A revision guide is a one-season item for most students. They use it, sit the exam, and never need it again. That means a guide in genuinely excellent condition can be picked up for a fraction of its cover price the moment exams finish.
Where to look in late June and July, while supply is at its peak:
- eBay — search "GCSE revision bundle" or "[subject] revision guide" and sort by newly listed. Bundles of several subjects often go for a couple of pounds per book.
- Facebook Marketplace — local, often cheaper, and you skip postage. Search your town plus "revision guides."
- Music Magpie and other used-book sites — good for individual titles at a fixed price with no bidding.
- Charity shops — July is when the post-exam donations land. Oxfam Books and bigger high-street charity shops are worth a browse.
One tip that saves money and stress: check the edition before you buy. For most subjects you want the current "Grade 9–1" specification. Older editions are cheaper and still useful for practising past papers, but make sure the core content matches your child's exam board (AQA, Edexcel, OCR).
If you're selling: clear the shelf and make a bit back
Finished your exams? Those guides are worth more than the recycling bin. A clean GCSE or A-Level guide still has real resale value, especially in the run-up to September, when the next year group starts buying.
How to get the most for them:
- Sell now, or hold until late August. Demand climbs sharply at back-to-school. If you can wait, you'll usually get more in September than in July.
- Bundle by subject or year. "Full set of GCSE Triple Science guides" sells better — and for more — than the same books listed one by one.
- Photograph honestly and price to move. Used revision guides are a volume game. Clear, well-lit photos and a sensible price beat holding out for top dollar.
- Mention the spec and exam board in the title. Buyers search for "AQA GCSE Biology revision guide," not just "biology book."
The most in-demand subjects — the ones that sell fastest — are Maths, Combined and Triple Science, and English Language & Literature. If you've got those in good nick, they'll go quickly.
Build a revision kit, not just a pile of books
A guide on its own is one thing. A system is what actually helps students revise — and it makes a thoughtful, low-cost gift for anyone starting their GCSE or A-Level year in September.
A simple "revision survival kit" — under a tenner from The Works, Poundland or B&M:
- A current-spec revision guide for each core subject
- Blank flash cards (for active recall — the single most effective revision technique)
- A mini whiteboard and dry-wipe pen
- Highlighters and sticky index tabs
- A wall planner or study timer to map out the term
It's far cheaper than buying a pre-made "revision bundle," and you can tailor it to the exact subjects and exam boards that matter.
The takeaway
Exam season ending isn't the end of the revision-guide story — it's the cheapest moment of the whole year. Buy second-hand now for next year, sell your finished guides into the September rush, and build a proper kit rather than paying over the odds for new books one at a time.
A little timing goes a long way.
