About Cognito
What Is Cognito
Cognito is a study platform for exam prep, built for secondary-school and college students who sit UK and international exams. It covers KS3, GCSE, A-Level, IB and AP qualifications, and it pulls everything into one place: short video lessons, written notes, practice questions, flashcards and an AI that tells you where your answers went wrong. The site sits at cognito.org, and it has grown to over a million students across more than 100 countries.
The app works by breaking each subject into small topics you can finish in a few minutes. That chunking matters for revision, because long textbook chapters are hard to return to when you only have a bus ride. Cognito keeps the same subject structure across its videos, quizzes and flashcards, so a topic you watch, then test and then memorise all line up.
The main limits are coverage and depth. Cognito is built around UK exam boards first, so students outside that system find less relevant material. And while the core lessons are free, the site is designed as a supplement to classwork, not a replacement for a teacher or a full course.
Getting Started
- Go to cognito.org and pick the reading mode, then create a free account with an email.
- Choose your qualification and exam board, then select your subjects from the list.
- Open a topic, watch the video lesson and read the short notes underneath.
- Answer the quiz questions at the end, then use flashcards to lock in what you got wrong.

Key features
Video Lessons
Each topic opens with a short video that explains one idea clearly, with illustrations built to make abstract points easier to picture. Lessons run long enough to cover the concept but short enough to hold attention. It is the feature most students point to when they say a five-minute clip taught them more than a full class period.
Quiz Questions
Cognito carries a bank of over 1.5 million quiz questions you can answer topic by topic. You can also build your own quizzes to test yourself across several topics at once, which mimics a real exam better than a single-topic drill. Answers come with feedback so you can spot what you misunderstood right away.
Flashcards
The flashcard decks let you flip through key concepts and definitions for quick recall. You can build your own decks to match what your class is covering, and reviewers regularly mention using them for a few minutes each morning. Repetition like that is what turns a definition you recognise into one you remember under pressure.
AI Feedback
Cognito's AI looks at your answers and explains where you went wrong, rather than only marking them right or wrong. You get the reasoning behind a correction, which is the part a marking sheet usually misses. It is aimed at the moment you get stuck, not at grading you.
Progress Tracking
The platform tracks what you have studied and where you are losing marks. Seeing your weak topics in one view helps you decide what to revise next instead of guessing. It turns a vague sense of "I am behind" into a concrete list of things to fix.
Subject and Exam Board Coverage
Cognito spans over 15 subjects and more than 300 courses, mapped to 10 UK and international exam boards including AQA, Edexcel, OCR, CIE, SQA and WJEC. History, economics, languages and religious studies sit alongside the core sciences and maths. Picking your board keeps the material aligned with what actually shows up on your paper.
Pros and cons
Pros
- Free to use, including video lessons, quizzes and flashcards, with no subscription needed.
- Short, well-illustrated videos make hard topics easier to absorb than a textbook page.
- Covers many subjects and maps to specific exam boards, so the material matches your syllabus.
- Quiz and flashcard tools let you find and fix gaps instead of rereading passively.
Cons
- Tied closely to UK and international exam boards, so students on other systems find limited use.
- Free video content runs on YouTube, which needs a connection and can be blocked on some school networks.
- Written notes stay brief, so deep-dive topics may still need a textbook alongside.
- No public API, so schools cannot plug Cognito into their own learning systems.
