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."

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."

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.
