Cognito
Free animated video lessons, notes, quizzes and AI-marked past papers for GCSE, A-Level, IB and AP Maths and Science.
For STEM revision, Cognito is one of the strongest free options you can point a student at. The combination of animated video lessons, written notes for every topic, 1.5 million auto-marked questions with a custom quiz builder, custom flashcard decks, and AI marking on past papers covers the full revision loop without a paywall. Students report a 2.5-grade average improvement, though that figure is self-reported by the platform. Compared with Seneca Learning or Quizlet Plus, neither of which is free at scale, Cognito's price is its weapon. If your revision need extends beyond Maths and Science, Save My Exams or BBC Bitesize will cover more ground. Teachers wanting class analytics should

Skip Cognito if your revision need sits outside Maths and Science, or if you need offline access, a native mobile app, or teacher-level class analytics rather than individual student practice.
The student platform is used at no cost with no ad layer, which puts it in a different bracket from paid revision services such as Seneca Learning or Quizlet Plus, and from paid resource libraries like Save My Exams. If your budget is zero, Cognito competes on coverage rather than price; if you need humanities or multi-subject depth, that budget still has to go elsewhere. Schools evaluating Cognito usually need to talk to the vendor about the schools offering.

About Cognito
Cognito is a free revision platform for students taking KS3, GCSE, A-Level, IB and AP Maths and Science. It hosts over 300 courses spanning 15 subjects — Biology, Chemistry, Physics, Mathematics, Further Mathematics, Computer Science, Geography, History, Economics, English Language, English Literature, Religious Studies, French, Spanish and German — mapped to 10 UK and international exam boards including AQA, Edexcel, OCR A and B, CIE, IGCSE, WJEC, CCEA, SQA, IB and AP. Study material comes in four main forms: short animated video lessons and written revision notes for every topic, more than 1.5 million auto-marked quiz questions you can also assemble into your own custom quizzes, custom flashcard decks, and exam-style questions plus past papers with AI marking and instant feedback. Progress tracking sits across all of it, and there is a schools offering alongside the individual student product. The headline numbers on the homepage are 1M+ students across 100+ countries, an average improvement of 2.5 grades, 80% of students staying from GCSE through to A-level, and 184 million+ views on the companion YouTube channel. There is no ad or paywall layer on the student site, and it runs in a browser rather than as a native desktop or mobile app.
Behind the Verdict
Cognito's pitch is simple: everything a GCSE or A-level STEM student needs to revise, for free, with no ads. It mostly delivers. The four content pillars — video lessons with animations, topic-level revision notes, an auto-marked question bank of over 1.5 million items, and exam-style questions plus past papers with AI marking — map cleanly onto how students actually revise: watch, read, drill, then test under exam conditions. The custom quiz builder and custom flashcard decks are the parts that make it more than a video channel; you can build a quiz across multiple topics rather than being confined to the pre-built sets, and one reviewer on the homepage describes working through a whole biology topic on the bus using flashcards. The curriculum breadth is unusually good for a free product — 300+ courses across 15 subjects and 10 exam boards, with explicit coverage of OCR A and OCR B separately, plus CIE Ireland, IGCSE, SQA, WJEC, CCEA, IB and AP, so international students aren't locked out. Progress tracking gives you a picture of where you stand rather than just how much you've clicked through. The honest constraints: this is a Maths and Science revision tool, and while the subject list includes English, History, Geography, Economics and languages, the platform's identity and its AI marking feature are built around STEM exam practice. There's no dedicated desktop or mobile app — you revise in a browser, including on mobile — so anyone wanting offline downloads or push reminders is out of luck. AI marking on past papers is documented as available, but the site doesn't explain how its grading compares to a human examiner, so treat it as a fast feedback signal rather than a guaranteed mark. There is a schools offering, but the public pages don't detail teacher analytics or class management, so teachers evaluating it for cohort-level insight should check directly. Setup is essentially nil: create an account and pick your course. The right way to read Cognito is as the default free revision resource for a UK or international STEM student, and as a supplement rather than a replacement for a tutor, textbook or a broader multi-subject platform.

Real-world workflow fit
Concrete scenarios for the personas Cognito actually fits — and what changes day-one when you adopt it.
Pick your exam board and course, work through the video lesson then the notes for each topic, then build a custom quiz across the topics covered so far to surface gaps.
Outcome: A running list of weak topics you can re-watch and re-drill, with progress tracking showing what's left before the exam.
Move from topic quizzes to exam-style questions and past papers, submitting written answers for AI marking and reviewing the instant feedback against the mark scheme.
Outcome: Faster feedback loops on long-answer questions than waiting for a teacher to mark them, plus familiarity with the exam paper format.
Use the structured lessons and revision notes as the teaching spine, then set the auto-marked quizzes as end-of-topic checks and have your child build flashcard decks for definitions.
Outcome: A complete term's worth of Science content with built-in assessment, at no cost, without needing to source a curriculum yourself.
Use Cases
- Revising GCSE Maths or Science with board-aligned video lessons and auto-marked quizzes
- Preparing for A-Level Biology using custom flashcards and AI-marked past papers
- Building a multi-topic custom quiz to find gaps before a Physics mock
- Homeschooling KS3 Science with structured lessons, notes and assessments
- Self-studying IB or AP Biology, Chemistry or Maths against the full syllabus
Limitations
- Cognito is a Maths and Science revision platform.
- Coverage spans 15 subjects across 10 UK and international exam boards — Biology, Chemistry, Physics, Mathematics, Further Mathematics, Computer Science, Geography, History, Economics, English Language, English Literature, Religious Studies, French, Spanish and German — but the product's depth and its AI marking feature are oriented toward STEM exam practice.
- Access is through a web browser, including on mobile browsers; there is no dedicated desktop or native mobile app, so offline revision isn't supported.
- AI marking is available on past papers, but the site does not document how its grading compares with a human examiner, so it's best treated as fast directional feedback.
- The platform is built for students studying GCSE, A-Level, IB and AP qualifications, not university or professional learners.
- A schools offering exists, but the public pages don't detail teacher analytics or class management capabilities.

Where the pricing makes sense
The company stage and team size where Cognito's pricing actually pencils out — and where peers do it cheaper.
The student platform is used at no cost with no ad layer, which puts it in a different bracket from paid revision services such as Seneca Learning or Quizlet Plus, and from paid resource libraries like Save My Exams. If your budget is zero, Cognito competes on coverage rather than price; if you need humanities or multi-subject depth, that budget still has to go elsewhere. Schools evaluating Cognito usually need to talk to the vendor about the schools offering.
Setup time & first value
How long it actually takes to get something useful out of Cognito — broken out by persona, not the marketing-page minute.
Individual students: create an account, pick your exam board and course, and you can start a lesson in under five minutes — there's nothing to install and it runs in the browser. Parents setting up a homeschooling child: the same, plus a few minutes browsing the course list to confirm the right level and board. Teachers or schools wanting class-level use should expect to contact the vendor about
Switching to or from Cognito
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From YouTube revision channels: use Cognito's video lessons as the structured spine, then add the auto-marked quizzes and flashcards you don't get from a video channel.
- →From paper revision guides: switch topic-by-topic to the revision notes and work the 1.5 million auto-marked questions as practice, keeping printed books for long-form reading.
- →From Quizlet: rebuild your decks in Cognito's custom flashcards alongside the topic quizzes, so memorisation and exam practice sit in the same place.
- →From Seneca Learning: replace paid question sets with Cognito's free auto-marked quizzes and AI-marked past papers for Maths and Science subjects.
- ↗To Save My Exams: if you need coverage beyond Maths and Science plus more written exam-technique content, move the humanities and language revision there.
- ↗To BBC Bitesize: if you want multi-subject free coverage at a broader but shallower level, especially for subjects Cognito doesn't cover deeply.
- ↗To a tutor or paid platform: if you need human-marked long answers and detailed feedback, use Cognito for daily practice and a tutor for assessment.
