Premium 1:1 Mathematics Tuition · KS3 · IGCSE · A-Level
Bespoke one-to-one mathematics tuition for ambitious international students from KS3 through IGCSE and A-Level. Every programme is personally designed around the student, the examination, and the outcome they are working towards — from closing critical gaps to accelerating well beyond the school curriculum.
Who We Work With
Premium tuition is most valuable when the objective is clear: stronger foundations at KS3, a higher IGCSE grade, an early qualification, recovery from weak teaching, A-Level success, or a long-term academic plan.
01 / EXAM PERFORMANCE
Focused work on the exact knowledge, reasoning and examination habits needed to turn strong potential into reliable performance.
02 / ACCELERATION
Structured progression for students capable of taking IGCSE or A-Level Mathematics earlier than the standard school timetable.
03 / RECOVERY
Precise diagnosis identifies what is actually holding the student back, rather than reteaching entire topics unnecessarily.
04 / LONG-TERM PLANNING
Mathematics tuition can be aligned with A-Level choices, university ambitions and the student's wider academic trajectory.
The Private Programme
One-to-one tuition should be genuinely individual. The programme evolves as performance changes, exams approach and new priorities emerge.
STEP 01
Review current attainment, school context, previous papers and specific strengths and weaknesses.
STEP 02
Build a focused programme around the student's examination board, timeline and goals.
STEP 03
High-level one-to-one teaching, targeted practice and direct correction of misconceptions.
STEP 04
Use performance evidence to adjust the programme and concentrate effort where it will make the greatest difference.
Why Premium 1:1?
The value comes from judgement: knowing what to teach, what not to teach, when to accelerate, when to consolidate, and how to connect today's lesson to the student's eventual examination and academic goals.
Typical Tutoring
Sigma Premium Tuition
Your Tutor
Andy's background includes mathematics teaching, school leadership, sixth-form and university-readiness work, and school improvement across UK and international education. That wider experience matters when a student needs more than explanations of algebra or trigonometry: it allows tuition to sit inside a much broader academic plan.
What Families Say
The goal is not to create dependence on a tutor. It is to help students become more capable, more precise and better prepared for the decisions and examinations ahead.
“Portia gained understanding, filled learning gaps, and is now extremely well prepared. We are very grateful for your help.”
International School Parent · South East Asia
“Thank you for helping me achieve the Maths grade I needed to progress to university. I recommended my brother because of the support I received.”
Former Student · University of Leeds
“The lessons built confidence and made a real difference in exam performance.”
GCSE Parent
Current Programmes
Strong foundations, confidence and acceleration for students before IGCSE, with teaching pitched above routine homework support.
Cambridge and Pearson Edexcel preparation, including structured content teaching, past-paper work, exam strategy and targeted intervention.
One-to-one support for A-Level Mathematics, including transition from IGCSE, advanced problem solving, exam preparation and accelerated pathways.
Simple Pricing
The fee is the same whether the student is building foundations at KS3, preparing for IGCSE, or studying A-Level Mathematics. Families are paying for individual attention, experienced academic judgement and a programme designed around the student — not for a different label on the syllabus.
Premium 1:1 Tuition
A single transparent rate across all currently offered mathematics programmes.
Private Tuition
Sigma's premium tutoring is deliberately limited so that each student receives proper preparation, direct teaching and ongoing academic oversight. KS3, IGCSE and A-Level Mathematics are all offered at one transparent rate: US$100 per hour. If you would like to explore whether it is the right fit, start with a short application.
