What parents and students say
Real Results: Success Stories from Our High-Achieving Students
Over fifteen years of teaching mathematics, I've worked with students from a range of UK senior schools — including Epsom College, Fettes, Wycombe Abbey, City of London Freemen's School, Stowe, and others. The testimonials below are from real parents whose children worked with me, sharing their own experience of the programme.

Testimonials | Guffick Tuition
Brighton College
Supporting a Brighton College student in her A-level Maths and Further Maths over the past two years has been an incredible journey. Initially underperforming, she has now achieved predicted grades of A* in both subjects, thanks to our focused and strategic approach. Her remarkable improvement was acknowledged by her school, paving the way for university applications to Yale, Harvard, Princeton, MIT and Carnegie Mellon, with interview invitations already underway.

"Lee is very structured in his teaching and provides clear, thorough explanations. He is patient and always happy to revisit a topic if necessary. I would have no hesitation in recommending him."

Concord College
Our Founder Lee Guffick supported a Concord College student who began our sessions with a grade C in A-level Maths. With a personalised teaching plan and consistent encouragement, the student achieved an A* in his final exams, exceeding all expectations.

"Mr Lee Guffick has been excellent for our son. With Lee’s exceptional teaching, my son achieved an A* for Pure Maths/Mechanics in his first year of A-levels. We highly recommend him."

Whitgift School
Over five years, Lee Guffick has worked with a Whitgift student from Year 7 to Year 11, helping him progress from below-average assessments to consistently achieving results above his class average. He is now considering A-level Maths. Additionally, I supported his sisters, one of whom improved from an E to an A* in A-level Maths, earning a place at Imperial College London for Medicine. The other achieved an A in Maths and is studying Law at Manchester University.

"Lee has been by far one of the best tutors for my children. He is patient and encourages them to reach their best potential."

Take Me ThereCase Studies | Guffick Tuition
A selection of past student journeys, showing how the same precision-led approach adapts to different challenges. Note that current programmes focus on GCSE and A-Level Mathematics; some of the case studies below cover entrance and scholarship preparation work from earlier years, included to demonstrate range of teaching contexts rather than as advertised current services.
Case Study 1:
Preparing a Sussex House Student for the King’s Scholarship Entrance Exam at Eton College - Lee Guffick Reflections
"By the time of the exam, he not only demonstrated mastery of the material but also a newfound ability to tackle challenges with resilience and independence."
Case Study 2:
Preparing a Student for 16+ Maths Entrance Exams at King’s College School, Wimbledon, and Latymer
"Her progress was remarkable—she performed exceptionally well in both entrance exams and received offers from both schools, ultimately choosing King’s College School, Wimbledon."
What I bring to the work
Fifteen years in the classroom, an MA in Mathematics Education from Warwick, active examining work alongside the teaching, and a methodology built around the specific patterns where students lose marks. The testimonials above describe what that adds up to in practice.
