## What is GradeNine?

GradeNine is your AI exam coach for UK GCSE, IGCSE, A Level and IB Science. Write any answer, tap Mark, and within seconds GradeNine breaks it down sentence by sentence against your exam board's published assessment criteria.

Requires an internet connection. GradeNine's marking, hints and questions are powered by AI models that run on our servers, so the app needs to be online to work — it does not function offline.

WHAT IT DOES

• Per mark feedback. See exactly which sentence earned the mark, which one missed, and the phrase examiners actually want.
• Real spec coverage. Every Biology, Chemistry and Physics specification across AQA, OCR, Pearson Edexcel, WJEC and Eduqas at GCSE and A Level, plus IB Diploma.
• Examiner phrasing built in. Tap any missed mark to see the precise wording the spec rewards.
• Adaptive practice. GradeNine tracks mastery per spec point and brings back the topics you keep getting wrong with spaced retrieval.
• Streaks, XP and daily goals.

HOW IT WORKS

1. Pick your exam board and specification at signup. Twenty seconds, no card.
2. Choose a topic or let Coggy, your AI tutor, pick today's question.
3. Write your answer or dictate it using voice on the Pro plan.
4. Tap Mark. About three seconds later you get a colour coded breakdown of every rubric point.
5. Tap any underlined phrase to see why it scored.

PRICING

Free forever for two marked answers per day, every specification, every board.

Pro Annual: equivalent to £6.58 per month, billed once a year at £79. Saves almost half.
Pro Monthly: £12.99 per month, cancel any time.
