GUFFICK TUITION
Specialist GCSE and A-Level Mathematics tuition for ambitious students
I'm Lee Guffick, a former Head of Mathematics and current Edexcel A-Level examiner, with 15 years' classroom experience in the state and independent sectors. Across those years I've come to a clear view: most able students don't lose marks on the maths itself. They lose them on the language of the maths — on how to read, interpret and answer exam questions with precision.
I run a small-group programme for a limited number of high-performing GCSE and A-Level students who want structured, rigorous preparation that holds under timed conditions.

After 15 years in the classroom — with many of those years as Head of Mathematics — I now run Guffick Tuition alongside my ongoing work as an Edexcel A-Level examiner.
Those two roles inform each other. Examining sharpens my understanding of how marks are awarded; teaching keeps that insight grounded in the real challenges students face.
Again and again, I see the same pattern: able students often do understand the mathematics. Where they lose marks is in how they read the question, structure their response, and express their reasoning with the precision the exam demands.
That gap — between knowing the maths and communicating it in the language the mark scheme rewards — is often where the difference between an A and an A* is found.
For me, good tuition isn't about covering more content. It's about closing that gap deliberately, until students leave able to write maths the way the exam rewards.
Programmes
Three cohorts, one programme. Each runs as a capped small group of ten students, live online, with the same approach to exam-question precision adapted to the stage.
Year 12 A-Level Mathematics
From the start of the course.
For Year 12 students at the start of their A-Level. Builds exam-question precision early in the course, so students enter Year 13 already fluent in the language of the exam — not learning it under pressure in their final term.
Year 13 A-Level Mathematics
Final-year preparation.
For Year 13 students preparing for the final A-Level examinations. Focuses on closing the gap between understanding the maths and communicating it in the way the mark scheme rewards. Timed-paper practice is built into the cadence, not bolted on at the end.
GCSE Mathematics
Grades 7–9 / Higher tier.
For GCSE students aiming for the higher tier and grades 7–9. The same precision-led approach applied to the GCSE syllabus and the structure of its three-paper assessment.
Is this programme right for your child?
The programme is built for students aiming for top grades — A and A* at A-Level, grades 7–9 at GCSE. It is not a homework-help group, a last-minute crammer, or a low-cost revision club. Students who succeed here typically have the mathematical capability already and want structured, precision-led preparation that holds under timed exam conditions.
