ABOUT SIMON

I am a Mathematics specialist, Pearson Edexcel Examiner and experienced international school leader.

Most recently, I served as Head of Secondary at Discovery Bay International School in Hong Kong, where I held overall accountability for academic standards, curriculum provision, student outcomes and public examination delivery across a secondary phase that grew from approximately 300 to over 500 students.

Alongside senior leadership responsibilities, I have continued to teach Mathematics, including Pearson Edexcel International A Level Mathematics, maintaining direct engagement with current specifications, examination requirements and effective classroom practice. 

As a Pearson Edexcel Examiner, I have extensive experience working with mark schemes, standardisation processes and large-scale assessment systems. In Summer 2026, I was awarded a Grade V examiner rating, recognising exceptional marking accuracy and quality assurance performance. 

WHY STUDENTS WORK WITH ME

Examiner Insight

As a practising Pearson Edexcel examiner, I understand exactly how marks are awarded and where students most commonly lose marks in examinations. Tuition focuses not only on learning the mathematics but also on improving examination performance. 

Genuine International A Level Expertise

I specialise in Pearson Edexcel International A Level Mathematics, including:

• Pure Mathematics 1–4

• Mechanics 1–2

• Statistics 1–2

This enables lessons to be highly focused on the specific demands of the qualification.

Educational Leadership Perspective

Having served as Head of Secondary and previously Deputy Director, Assistant Director and Head of Mathematics, I bring a wider understanding of educational success, university preparation and long-term academic development.

Proven Record of Academic Improvement

Throughout my career I have successfully improved student outcomes at both IGCSE and A Level, while supporting students applying for competitive university courses including Mathematics at Oxford and Cambridge.
