The AI Tutor Built for GCSE and A-Level
Ask a general AI tool a biology question and you'll get a perfectly good answer — for someone, somewhere, sitting some exam. It doesn't know your board, it hasn't read your mark scheme, and it can't tell you why you got 3 out of 6.
Medly is built the other way round. It's constrained to your exam board — AQA, Edexcel, OCR or CIE — working from content checked by qualified teachers, including senior examiners. Ask it about photosynthesis and you get the version your board examines, with the assessment objectives your marks actually depend on.
It marks your answer, not a model one
Anyone can show you a perfect answer. The useful bit is finding out what's wrong with yours.
- Write an answer, get it marked. Typed or handwritten on the built-in canvas — Medly goes through it like an examiner would: which specification points you hit, where the marks went, what to change.
- Bring any paper. Found questions elsewhere? Upload it and Flexible Marking handles it.
- It remembers what you don't know. Every answer feeds a picture of your understanding, topic by topic — so revision time goes where the marks are, not where the highlighters are.
Does it work?
Over 400,000 students have used Medly. In our 2025 GCSE analysis, 74% of surveyed students improved their grades while using Medly — methodology included, because a claim without one is just marketing.
How it compares
| Private tutor | Revision websites | Medly | |
|---|---|---|---|
| Cost | ~£24/hour (≈£96/month weekly) | Free–£12/month | Free to start; £24.99/month for AI marking and unlimited use |
| When | One hour a week | Any time | Any time |
| Marks your answers | In the lesson | Model answers only | Every answer, instantly |
| Knows your exam board | Depends on the tutor | Broadly | Constrained to your spec |
| Adapts to your gaps | Yes | No | Topic by topic |
A good tutor is brilliant — that's not the argument. The argument is an hour a week at £24 an hour, when most of what you need is someone to mark your practice and point at the gap. Medly does that part, every day, and the full cost comparison does the sums.
Free to start
Sign up and study every day at no cost — no card, no trial that quietly expires. The paid plan, £24.99/month or £180/year, unlocks AI marking and unlimited use. There's also the Medly Bursary Scheme, and Medly Mocks: free, examiner-made national mock exams.
FAQ
Is an AI tutor as good as a real tutor?
They're good at different things. Medly marks every answer instantly, any time, and never forgets which topics you find hard. A human tutor brings motivation and accountability. Plenty of students use both — the difference is that one costs ~£96 a month and the other starts free.
Which exams does it cover?
GCSE, A-Level, IGCSE, IB, AP and SAT, across AQA, Edexcel, OCR and CIE — maths, the sciences, English literature and language, and more.
Is it safe for under-16s?
Yes. Medly is built for school-age students, with safeguarding designed in from the start. The details are on our safety page.
Can it mark handwritten answers?
Yes — write on the built-in canvas or upload a photo of your answer, and it's marked against the real mark scheme.
How is this different from ChatGPT?
ChatGPT answers from the open internet. It doesn't know your exam board and won't mark against a specification. Medly is constrained to exam-board-specific content checked by qualified teachers, marks your exam answers, and keeps track of what you've mastered — because getting you marks is the whole job.
