Our interactive online tuition is undertaken one to one using a collaborative, interactive approach.
In Maths, we recommend that students have a way to write on the online whiteboard. Most students opt to use a inexpensive graphics tablet (e.g. the Wacom One). Other students prefer to use an iPad with Apple Pencil, or a Surface Pro with a stylus, or similar.
Having previously worked together at Harrow School Online, Harry and Katrina have joined forces to form Get Me That Grade, offering premium, bespoke one-to-one support in Maths and Biology. They are senior British teachers with a proven track record of helping their students to get the best grades in International A Levels in Biology, Maths, and Further Maths.
They each have years of experience at the UK’s leading independent schools and have helped support their students to some of the best results on the international stage. For example, in 2024, their students’ results were 100% A*-A in Biology and 86% A*-A in Further Maths
Their focus and specialism is International A Level in Maths, Further Maths, and Biology. They also offer Oxbridge preparation support. Harry offers support for GCSE and iGCSE maths, as well as for younger secondary school age students, having previously gained extensive experience in supporting students at Abingdon School and Bradfield College.
They are trusted by international families across the Middle East, South-East Asia, and Europe, who choose them for their expertise and great results as well as their calm, tailored teaching.
Lessons are structured and personal, with a focus on assisting students with their exam technique and steady confidence-building.
Both Harry and Katrina offer truly personalised 1:1 tuition with clear goals and measurable progress.
About us
How it works
Scheduling: UK London-based scheduling with regular availability for;
Europe
Middle East
South-East Asia
Format: Live, one-to-one online tuition sessions. Optional marked mock exams available.
Sessions: 55-minute lessons (effectively one hour), typically one to three sessions per week.
Method: Structured explanations, worked examples, and guided practice with explicit exam-technique coaching.
With our exceptional subject knowledge and experience teaching very highly attaining students, we can provide the stretch and challenge that the brightest students might be lacking in a normal classroom setting. No matter the academic level of the student, we aim to get the best out of every student.
We are experienced with home-educated students and emotionally based school avoidance, and teach in a calm, structured manner. For details of adjustments, access arrangements and routines, please see our dedicated SEN Support page.
We teach the Pearson Edexcel International and Cambridge International specifications, and support families across the Middle East, South-East Asia, and Europe.
Both tutors are DBS checked and on the DBS Update Service.
