Add the work
Paste notes or upload a worksheet, PDF, Word doc, image or revision sheet.
It starts with the messy bit: notes, worksheets, half-remembered lessons.
Most revision apps begin with a giant menu of topics. GradeNinja begins with what the pupil has in front of them today, then turns that into practice they can repeat.
Make it testable
Generate questions or flashcards, then save them under the right subject.
Keep it alive
Wrong answers come back as reviews, not as vague "try harder" advice.
What makes it different
Less portal. More training session.
A good revision session is short, specific and honest. GradeNinja keeps the game layer, but the point is the work: retrieval, correction, spaced review and visible progress.
Personal packs
School material becomes saved practice, not a one-off chat response.
Topic practice
KS3 and GCSE subjects are split into smaller chunks pupils can finish.
Feedback that says what to fix
Hints, explanations and mark-style comments after mistakes.
No feed, no adverts
The app can be fun without becoming another thing to scroll.
Fun on the surface. Boringly sensible underneath.
Pupils
Short runs, XP, battles and a guide character, but every game hook points back to a question, flashcard or review.
Parents
A clearer answer to "did you revise?" What was practised, what was missed, and what needs another pass.
Schools
Retrieval practice and homework support without a social feed, adverts or public pupil messaging.
GradeNinja came from a real revision fight at home.
It had to be useful enough that the work improved, and lively enough that opening it did not feel like losing an evening.
