The lemma method

Every GCSE and A-Level maths exam is around 67% mechanical questions. Master those first, then build clear conceptual understanding.

Most students lose marks not from lack of understanding but from failing to drill the patterns they already know. lemma fixes the floor before building the ceiling.

Phase 1: Mechanical
~67%
Pattern recognition, procedural fluency, method marks. Drilled to automaticity so you bank these marks every time.
Phase 2: Conceptual
~33%
Proof, novel problems, deeper understanding, built on a solid mechanical foundation, using visualisations and Socratic dialogue.
Features

Everything your grade needs.
Nothing it doesn't.

Built around a specific revision philosophy, where every feature earns its place.

Pattern drilling engine
Curriculum-mapped questions by topic and exam board target the marks you're most likely dropping. Your weak patterns get drilled until they're automatic.
Pre-loaded exam content
lemma already has every past paper and the full curriculum loaded for your exact exam. Upload your own notes to personalise it further.
abc
Skip the typing
Scan the QR code in your session, point your phone at your written answers, they're uploaded automatically and read by lemma. Save time typing up answers.
A*
Predicted grade
Activates after your first paper attempt and updates in real time as your weak areas improve. Follows official grade boundaries for your exact exam board.
Predicted paper
Generated from years of frequency analysis, weighted by how marks have actually been allocated. Attempt it in past paper mode, just like the real thing.
Mark loss analysis
lemma tracks exactly which question types you consistently lose marks on. Those gaps get prioritised.
A recipe for improvement.
Past paper mode
Screen goes blank, the timer starts, and there's no help until you're finished. lemma marks your paper question by question and feeds your predicted grade.
Blackout mode
lemma generates your formula and definition sheet, then hides it so you recall from memory. Repetition of this process results in key content memorised.
Visual explanations
Original animations slide into the chat, moving through graphs, geometric proofs, and more. Built to make abstract concepts click instantly.

Your tutors

Two personalities.
One method.

Both follow the same revision philosophy. The difference is how they get you there.

P
The Professor
Rigorous, precise, Socratic. Builds understanding from first principles and won't let sloppy reasoning pass unchallenged. Best for proof work, chains of reasoning, and mark-scheme precision.
S
Study Buddy
Warm, conversational, encouraging. Works through problems with you like a peer. Best for drilling and late-night revision.
