# Cognito

> Cognito is a revision platform for KS3, GCSE, A-Level, IB and AP students, and US middle and high school science. Each course follows one exam board's specification, so students only revise what's on their exam. Most GCSE and KS3 courses have revision notes, quizzes, flashcards and exam-style questions for every topic, plus past papers; many A-Level, AP and 7+ to 16+ entrance exam courses are past papers. It's free to start, with a paid Pro plan.

Over 1 million students have used Cognito, and on average students improve by 2 grades. Courses cover the sciences, maths, English, humanities, languages and more, for UK boards (AQA, Edexcel, OCR, WJEC, CCEA, SQA) and international ones (Cambridge, Edexcel International, Oxford AQA, IB and College Board AP). Written exam answers can be marked by AI. Schools can buy Cognito for their students.

Each course below links to its main page, usually its revision notes. A course's other tabs sit at the same address with the tab's name as the last segment, for example `/quiz`, `/flashcards`, `/exam-practice` or `/past-papers`.
