About Revizona
Revizona helps IGCSE and A Level students do the thing that works best for exams: practise real exam-style questions, get marked straight away, and fix the exact mistakes that cost marks.
Why we built it
Past papers are the most effective way to revise, but marking your own answers is slow and easy to get wrong. Most students never find out why they lost a mark. Revizona marks each answer against the mark scheme in seconds, explains what was missing, and keeps track of the topics you need to revisit.
What we do
- Practice questions for Cambridge IGCSE and A Level and Pearson Edexcel International GCSE, organised by syllabus topic.
- Instant marking: a rule-based marker for short answers and an AI model for written answers, with a human review route for any mark you disagree with.
- Clear explanations and a progress map by topic.
- Free revision guides on our blog, written to match the official syllabuses.
How we check our content
We check exam facts in our guides against the official Cambridge and Pearson syllabus documents. We review questions before they go live, and we compare samples of AI marks with human marking to find and fix errors. AI marks can still be wrong, so you can ask a person to review any mark. Read how AI marking works and its limits in our AI Marking notice.
