Description
Cognito is a free online revision platform for secondary and pre-university students studying toward GCSE, A-level, IB, AP and Key Stage 3 exams. What began as a Maths-and-Science resource has grown into a full-subject platform covering 15 subjects, including Physics, Chemistry, Biology, Mathematics, Further Mathematics, Computer Science, Economics, History, Geography, English Language, English Literature, Religious Studies, French, Spanish and German, mapped to ten UK and international exam boards (AQA, Edexcel, OCR A, OCR B, WJEC, CCEA, SQA, CIE, IB and AP).

The platform organizes over 300 courses around short video lessons and written revision notes for every topic, backed by a bank of more than 1.5 million quiz questions students can answer topic by topic or assemble into a custom quiz. A flashcard system lets students build and study their own decks to memorize key facts and definitions. For exam preparation specifically, Cognito provides exam-style questions and past-paper style practice with AI marking, so a student gets feedback on a written answer rather than only a multiple-choice score.
Cognito reports that its video lessons have accumulated more than 184 million views and that students who use the platform improve by an average of two to two-and-a-half grades, along with a claim that 80 percent of students who start on Cognito for GCSE stay on it through A-level. The service says it is used by more than a million students across over 100 countries and is free to use, with sign-up required to track progress and save flashcard decks or quiz results.
Cognito is aimed at students studying independently or supplementing classroom teaching, rather than at teachers looking for a classroom management tool, though a separate area of the site addresses schools. Its core strength is Maths and Science, its original focus, with humanities and languages added as the subject list expanded; coverage depth may vary more by subject as a result.
