Pearson Edexcel IGCSE & Additional Maths tuition

Specialist one-to-one online tuition for students aiming for top grades in IGCSE Maths and advanced qualifications beyond the standard GCSE curriculum.

Harry is a fully qualified Maths teacher with Qualified Teacher Status (QTS), a current Pearson Edexcel International A Level Maths and Further Maths examiner, and former Head of Mathematics at Harrow School Online and Highgrove Education.

Harry supports students studying Pearson Edexcel International GCSE Mathematics, including Mathematics A (4MA1) and Mathematics B, alongside students taking qualifications designed to extend beyond the standard GCSE and IGCSE curriculum.

These include:

  • Pearson Edexcel International GCSE Further Pure Mathematics

  • OCR FSMQ Additional Mathematics

  • UK GCSE Mathematics, particularly Higher Tier students preparing for further study

Harry works with students across a range of starting points, including those aiming for grades 8 and 9, students already performing strongly who want to close the final gaps in their examination performance, and students using Additional Maths or Further Pure Mathematics as preparation for A Level or International A Level Maths.

How tutorials work

Lessons are live, one-to-one, and past-paper driven.

Harry Williams, Get Me That Grade Maths tutor and Pearson Edexcel IAL examiner, delivering an online Mathematics tutorial.

iGCSE and GCSE Maths is characterised by a broad set of mathematical techniques that students need to practice repeatedly, over time, in different contexts, so that they develop fluency and automaticity. Many students are held back from achieving their full potential in maths, particularly as they have not had the opportunity to receive 1:1 support with their algebra; many students have not undertaken a structured programme to allow them to go step-by-step to mastery.

The way in which knowledge and understanding in maths is built step-by-step means that if students have shaky foundations, it is very easy for problems to snowball. It is often the case that students missing these fundamentals are at risk of being left-behind, with more advanced topics which build upon these shaky foundations being at risk of being inaccessible to these students.

Tuition with Harry can help a student to fill in the gaps, strengthening foundational skills and allowing the student to develop understanding at their own pace in a supportive and encouraging 1:1 setting.

Tuition with Harry involves:

  • A carefully designed, personalised programme with built-in review points where the plan is honestly reassessed.

  • Homework set after every tutorial, tailored to the student's needs and personally marked by Harry, with feedback to help identify mistakes, consolidate understanding, and guide future lessons.

  • Parent progress updates at regular intervals.

Sessions are 55 minutes, scheduled online from the UK with availability for families in Europe, the Middle East and South-East Asia.

Support from an experienced classroom and online teacher with examiner insight

Harry has taught students from Year 7 to Year 13 at:

  • Bradfield College

  • Abingdon School

  • Harrow School Online

  • Highgrove Education

He understands the knowledge students need at GCSE and IGCSE, as well as the algebraic fluency, problem-solving habits, and mathematical precision required for stronger performance in iGCSE and bridging qualifications, such as the FSMQ Additional Maths qualification for OCR.

Harry is also experienced in supporting home-educated students, international students, and those who work best in a calm, structured one-to-one environment.

His lessons focus on the areas that matter most in Maths:

  • Understanding the mathematics properly

  • Recognising what a question is testing

  • Selecting an efficient method

  • Presenting mathematical arguments clearly

  • Avoiding errors that cost otherwise strong students marks

  • Using examination time effectively

Qualifications that Harry Teaches

Harry offers tuition for students studying:

  • Pearson Edexcel International GCSE Mathematics A (4MA1)

  • Pearson Edexcel International GCSE Mathematics B

  • Pearson Edexcel International GCSE Further Pure Mathematics

  • Cambridge OCR Level 3 FSMQ Additional Mathematics, often known as Add Maths

  • Pearson Edexcel Level 2 Extended Mathematics Certificate

  • Pearson Edexcel GCSE Mathematics

  • Pearson Edexcel Advanced Extension Award (AEA) Mathematics

In everyday language, families may refer to some of these courses as IGCSE Maths, IGCSE Further Maths, Add Maths, GCSE Maths, or GCSE Further Maths. Harry can help identify the exact qualification and specification where needed.

Harry also offers a small number of pre-GCSE places.

When booking, please state the exact qualification, examination board, specification, and tier where applicable.

iGCSE & GCSE Maths support

Pearson Edexcel IGCSE Maths is a distinct qualification from standard UK GCSE Maths, although there is a great deal of overlap between their specifications. Students often need similar mathematical support: secure algebra, confident number work, accurate notation, clear method, and stronger examination technique.

Harry has taught and tutored both GCSE and IGCSE Maths, including students in the UK and overseas. He has also taught the Cambridge OCR FSMQ Additional Maths qualification and has supported students preparing for the Pearson Edexcel Advanced Extension Award (AEA) Mathematics. Harry is particularly well placed to support families choosing, navigating, or preparing for Pearson Edexcel iGCSE routes, where the structure can feel less familiar than standard UK GCSE Maths.

This support may suit students who are:

  • Studying GCSE or iGCSE Maths in the UK or overseas

  • Taking Pearson Edexcel iGCSE because it is offered by their school, online provider, or examination centre

  • Preparing independently or as a home-educated student

  • Aiming for grades 8 or 9

  • Taking a Further Maths or Further Pure Mathematics qualification alongside their main Maths course

  • Secure with routine questions, but less confident with unfamiliar or multi-stage problems

  • Looking for more challenge than their current school curriculum provides

  • Preparing for more advanced Maths in Sixth Form

Harry will tailor the work to the student’s actual course rather than assuming that all GCSE, iGCSE, and additional maths qualifications are identical.

Testimonials and Google Reviews

“Harry’s individual approach to each student was particularly valuable. He identified the key weaknesses and areas for improvement, helping to develop a deeper understanding of individual topics and improve the way problems were worked through.

I also really appreciated his teaching style, the way he interacted with the student, and the passion he brought to the lessons. I would highly recommend Harry.”

“I did my Maths GCSE early in November and got a U. Harry became my tutor and I resat Maths. In the summer, I received my GCSE results and got a grade B.

The most useful thing about Harry’s tuition was everything! The biggest change for me was my understanding.

If another student was considering tuition, I’d say: have Harry as a tutor.”
