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.

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.
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.
