What Tassomai does well
Tassomai is built around revising little and often. Students answer short multiple-choice quizzes each day, and its algorithm sets daily goals, picks out weak areas and brings those topics back for more practice. When it spots a gap, it serves a short tutorial video of 60 to 90 seconds. Its AI tutor, Mai, gives hints and explanations on quiz questions without giving away the answer.
It began with GCSE science, mapped to AQA, Edexcel, OCR 21st Century, OCR Gateway, IGCSE and WJEC specifications. It now also covers Maths, English Language, English Literature, Geography, History, Computer Science, Latin, and vocabulary for French, Spanish and German, with content for Years 3 to 6 and for 11+ and 13+ Common Entrance. The Tree shows a student's knowledge growing, and parents get a dashboard to follow progress.
Where Medly is different
Written answers, marked
GCSE papers ask for more than choosing the right option. You'll write extended answers, show your working in calculations and plan 6-mark responses. In AQA's GCSE Biology, for example, about 40% of the marks are for knowledge and understanding, and about 60% for applying that knowledge and analysing information.
Medly's questions span more than 14 types, from multiple choice to 6-mark extended responses and essays, written to exam board specifications and checked by teachers and examiners. Each answer you write comes back annotated, showing which marking points you hit, where marks were lost and what to change, tied to the specification points and assessment objectives for your board. Every result feeds a mastery score for that topic, so Medly can suggest what to practise next.
An AI tutor that works through questions with you
Tassomai's Mai helps with quiz questions. On Medly, if you're stuck on a longer question, the AI tutor can work through it with you, and it remembers what you've covered before.
Handwritten answers
You'll sit most of your exams on paper, so Medly lets you practise that way. Write your answer on the built-in canvas with a pen, eraser and text tools, and handwriting recognition reads it so it can be marked. If you've done a past paper on paper, Upload & Mark lets you upload it and have that marked too.
Mocks run like the real thing
Medly Mocks are free mock exams set by examiners and sat by students across the country at the same time. They come with grade boundaries, a results day and a percentile showing where you sit in the cohort.
GCSE and beyond
Tassomai covers Year 3 to GCSE, offers AS-level science on request, and doesn't list A-Level, IB, AP or SAT courses. Medly covers GCSE, A-Level, IGCSE, IB, AP and SAT, so you can keep using it into sixth form.
Does Medly raise marks?
In a randomised controlled trial in GCSE science, students using Medly for 30 minutes a week for four weeks scored 22% higher on the post-test than classmates revising the same topic in their usual way, adjusted for where they started. That's 2.56 more marks out of 35 across 644 students, an effect size of 0.33.
The trial was designed, randomised and analysed by WhatWorked Education with Professor Steve Higgins of Durham University. You can read our summary of the trial or the paper on arXiv.
