Bitesize, now used by three-quarters of secondary students and half of those in primary schools, is one of the BBC's most successful online brands.

The Bitesize family of sites helps school students from 6 to 16 with their coursework, homework and test preparation for Key Stages 1 to 3, GCSE, Scottish Standard Grade and Highers, and subjects in Welsh. The sites provide 'bitesize chunks' of interactive learning content, including Flash activities, video and audio summaries, quizzes, games and mock exams.

Since it started in 1998, Bitesize has constantly evolved to keep pace with changes in technology, the curriculum and young people's expectations.
