Maths & Coding Lessons That Build Problem-Solvers
For ages 7–18, we teach the Olympiad way — developing logical thinking, creativity, and confidence.
Online or in London, from Primary to Senior level, we help students master advanced maths, coding, and skills for life.
Our Olympiad approach helps students get into top schools, win competitions, excel in exams, and progress to leading universities
9 out of 10 students improve their results, gain awards in maths and coding competitions, and strengthen their applications to selective schools and universities.

FAQ
Find quick answers to common questions about our lessons, pricing, scheduling, and how Exact Science can help your child excel.
- We hold our classes online or on-site on Saturdays at our branch in Pimlico Academy, London. You can find our timetable here.
- For lessons you only need a computer or phone with a microphone, camera and Internet access. Wherever you are — in London, Nottingham, New York or Bali — online lessons will be at hand.
- You can get acquainted with the school at any time convenient for you. To do this, just leave a request and sign up for a lesson.
- The trial lesson is a 30-minute online session designed to get a sense of how your child approaches mathematical thinking and problem solving. (In practice, it often runs a bit longer if the student is engaged!)
We typically explore a range of fun and challenging problems drawn from competitions. We adapt the difficulty based on how the student responds, aiming to make it both accessible and stimulating.
After the session, we'll have a quick conversation with the parent to share observations and suggest a personalised path forward. - It is OK, it happens! Students have the opportunity to cancel a lesson up to 8 hours before the scheduled time without loss of payment. You can reschedule for a convenient time, and the teacher will have the opportunity to plan accordingly.
