Teacher Profile

Dr Debra Dunstan-Sewell


I have a BSc & PhD in Physics, both from the University of Bath, and carried out aerospace research for eleven years. For seven years in a Christian primary school I taught Numeracy, Literacy, and Science in a God-centred way. Following this, I home educated my daughter up to and including A-Levels. She received four A* grades in A-Level Physics, Maths, Further Maths, and Chemistry.

I’m an experienced private tutor and have been described as “kind, encouraging, patient, not at all scary and very understanding”. I teach all ages and have experience at teaching students with dyslexia, dyscalculia, dysgraphia and maths phobia. My aim is always to enable students to pass their exams at the highest grade of which they are capable, whilst noticing the hallmarks of God’s design.

My lessons are relaxed and friendly in order to maximise learning. In this supportive environment my students get excellent results.

I offer the following PX Classroom courses:

KS3 Physics

This course whizzes through the KS3 Physics topics in just one year and prepares students to start my PX Classroom IGCSE Physics course.

IGCSE Physics

This is a two-year course aiming to be exam-ready for Edexcel.


I think the thing I like best about Dr. Dunstan-Sewell’s teaching is that she is so patient and happy to explain things until I really understand and can remember them.

Dr. Dunstan-Sewell is a great teacher and makes learning Science a lot of fun. I’ve actually enjoyed the subject for the first time ever!


Aged 13

Dr. Dunstan-Sewell is tutoring my son for IGCSE Physics with PX Classrooms. He has found the organised format helpful and Physics has become one of his favourite subjects.

My twelve-year-old son loved Dr. Dunstan-Sewell’s lessons. She is calm and encouraging. Her approach is logical and easy to follow.

My fourteen-year-old daughter is doing so much better … than when she was attending school. The great part is that my daughter really enjoys the lessons, and her confidence has grown. Dr Dunstan-Sewell’s teaching is excellent. We have great confidence that this is the most appropriate preparation for our daughter’s GCSEs in two years’ time.
