General Certificate of Secondary Education
GCSE
GCSEs are the foundation qualifications taken by students aged 14–16 across England, Wales, and Northern Ireland. They determine sixth-form and college entry, and set the stage for A-Levels, apprenticeships, and vocational pathways. Koydo builds an adaptive revision plan around your child's specific subjects and exam board — whether that's AQA, Edexcel, OCR, or WJEC — and uses an AI tutor to explain mark-scheme thinking step by step. From maths and English to the sciences, history, geography, and languages, every topic is covered with timed mock papers, flashcard drills, and progress-mapped spaced repetition.

Frequently asked questions
Which GCSE subjects does Koydo cover?
Koydo covers the most-sat GCSE subjects including Mathematics, English Language, English Literature, Biology, Chemistry, Physics (and Combined Science), History, Geography, Religious Studies, French, Spanish, German, and Computer Science. More subjects are added continuously.
Does Koydo support all exam boards?
Yes. You select your exam board (AQA, Edexcel/Pearson, OCR, WJEC, or CCEA) and Koydo filters content, past-paper questions, and mark schemes to match the exact specification you are studying.
Can parents track their child's progress?
Absolutely. A shared family subscription gives parents a read-only progress view showing completed sessions, mock-paper scores, and which topics still need attention — without interrupting the student's study flow.
How is Koydo different from a revision guide book?
A book gives every student the same content regardless of what they already know. Koydo starts with a diagnostic, identifies your specific gaps, and then delivers the practice, explanations, and mock papers most useful for you — updating in real time as your knowledge improves.
