In Year 10, students start their GCSE Maths course, with final exams at the end of Year 11. Building a strong understanding early gives them time to close any knowledge gaps and prepare properly for their exams.

I provide one-to-one and small-group GCSE Maths tutoring shaped around your child. Lessons consider their exam board and entry tier, Foundation or Higher. They also reflect your child’s current ability, with most of the time spent where they need support.

Some students come to me struggling with Maths, while others are aiming for a grade 9. Every lesson is built around what they need to succeed. For students working towards a target grade, I plan lessons to close the gap.

A Strong Focus on Exam Practice

Exam technique is part of every lesson from the start. Students learn how to apply their knowledge to GCSE exam questions and understand exactly where marks are awarded, including method marks. They also learn to spot and avoid the common mistakes that cost marks.

We work through past-paper questions together, building up to the harder problems at the end of each paper. By the time the exams arrive, those questions feel familiar rather than daunting.

What a Lesson Looks Like

Each lesson starts with a short recap of the last session and a look at any homework questions that caused problems. We then move on to the main topic, whether that’s something new or an area your child finds difficult, and I explain it step by step until it makes sense. The second half of the lesson puts that understanding to work on GCSE exam questions, and I finish by setting homework that targets what we’ve covered.

GCSE Maths Topics

Lessons cover all six areas of the GCSE Maths course:

  • Number
  • Algebra
  • Ratio, Proportion and Rates of Change
  • Geometry and Measures
  • Probability
  • Statistics

Lessons follow your child’s exam board specification and whether they are sitting Foundation or Higher tier.

I also tutor iGCSE Maths and the Level 2 Further Maths qualification that some schools offer alongside GCSE for students aiming for the top grades.

Regular Progress Updates

You shouldn’t have to wait for a school report or parents’ evening to find out how your child is getting on.

I call every parent at least once a month to talk through their child’s progress, including what’s going well and where they need more attention. Between calls, I keep in touch by WhatsApp with messages and voice notes, and you can reach me by phone or WhatsApp whenever you’d like to talk.

I set targeted homework where it will help. It gives your child extra Maths practice between lessons and lets me track their progress from week to week.

How Lessons Work

Every lesson is interactive. I follow your child’s working as they tackle each problem, so I can check their understanding in real time and make sure no gaps go unnoticed.

One-to-One Lessons

Every minute of a one-to-one lesson is focused on your child. I work at their pace and concentrate on the topics where they need the most help.

  • Individual attention throughout
  • Lessons shaped around your child’s needs
  • A flexible pace
  • Ideal for targeted improvement

Small-Group Lessons

Small groups of up to 10 bring together students studying the same course at a similar level. They learn from each other’s questions while still getting plenty of individual attention.

  • No more than 10 students in a group
  • Groups matched by course and level
  • Learning alongside other students
  • A structured pace
  • A more affordable option

GCSE Maths Tutor in East London and Essex

I’m based in South Woodford and tutor GCSE Maths students from across East London and Essex, including Woodford, Wanstead, Walthamstow and Loughton. Local schools use different exam boards, so I always match lessons to the specification your child is following.

If you’re looking for a GCSE Maths tutor near you, get in touch, and I’ll talk you through how lessons would work for your child.

About Me

I have a First Class Honours degree in Physics with Theoretical Physics from the University of Nottingham and graduated at the top of my cohort. Before that, I achieved A* grades in A-Level Maths and A-Level Physics.

I’ve been tutoring since 2020, specialising in Maths and Physics for students aged 11 to 18.

My approach is simple. I explain topics clearly and give students plenty of exam practice, with regular feedback so they keep making progress.

My degree is built on advanced mathematics, so I can explain a topic in more than one way until it clicks. I also know where GCSE content leads. Students planning to take Maths or Physics at A-Level leave my lessons with foundations that hold up when the work gets harder.

  • First Class Honours in Physics with Theoretical Physics
  • A* grades in A-Level Maths and Physics
  • Tutoring since 2020 · Enhanced DBS checked

I've been working with them since December 2025 and have seen massive improvements to my overall maths grade going from a 4 to a 7 in GCSEs. They have amazing tutors and the flexibility with bookings is phenomenal. They are greatly priced and I would heavily recommend them for anyone who wants to see improvement within their grades both A level and GCSE.

Couldn’t recommend a better tutor, he took me from a U in math to passing my GCSE’s no problem. Worth all the money you can give and thanks to him I can continue to college no problem without any resits 😁

Connor has been an excellent A Level Maths tutor throughout my son’s first year of A levels. He is knowledgeable, patient and encouraging, and has a real talent for explaining difficult topics in a way that makes them much easier to understand. His support throughout the year has really helped my son build his confidence and understanding, and achieve top marks in his first year. We’ve been really impressed with Connor and would highly recommend him.

Frequently Asked Questions

Do you tutor both Foundation and Higher tier GCSE Maths?

Yes. I tutor both tiers and can help you decide which is right for your child if the school hasn’t confirmed this yet.

Which exam boards do you cover for GCSE Maths?

I cover all major exam boards for GCSE Maths and match lessons to your child’s specification and past papers.

Do you teach iGCSE Maths and GCSE Further Maths?

Yes. I tutor iGCSE Maths as well as GCSE, and the Level 2 Further Maths qualification that some schools offer alongside GCSE.

When should my child start GCSE Maths tutoring?

The start of Year 10 is ideal, as it gives time to close gaps well before the exams at the end of Year 11. Students can also start in Year 11, when regular weekly lessons can still lift their grade. Some begin earlier, in Years 7 to 9, to build confidence before the GCSE course starts.

Is it too late to start GCSE Maths tutoring after poor mock results?

Not at all. Mock results are one of the most useful starting points I can have. I’ll go through the paper with your child and plan lessons around the topics that lost the most marks, so every week before the real exams counts.

Can you help my child revise for their GCSE Maths exams?

Yes. In the months before the exams, lessons turn to past papers and the topics your child finds hardest, so revision time goes where it will earn the most marks.

How much does GCSE Maths tutoring cost?

The cost of GCSE Maths tutoring depends on whether your child has one-to-one or small-group lessons, as group lessons cost less per student. I’ll talk you through the fees during a free, no-obligation call, once I understand what they need.

Is one-to-one or group tutoring better for GCSE Maths?

One-to-one lessons suit students with specific gaps or those who need to build confidence. Small groups of up to 10 work well for GCSE exam practice and revision. I’ll recommend the best fit after our first chat.

What does my child need for GCSE Maths lessons?

A laptop or tablet with a stable internet connection, plus a scientific calculator. A mouse or stylus makes it easier to write out their working, and I’ll make sure everything is set up before the first lesson.
