Maths & Codingfor Problem-Solvers
Structured preparation for Olympiads, competitions, and deep mathematical thinking.
The journey
From curious student to confident Olympiad thinker
One clear route: start with foundations, build problem-solving depth, then move into competitions and university-level thinking.
- Primary
Foundations (7–11)
Build number sense, logic, and clear mathematical communication through games and early Olympiad-style tasks.
- Junior
Problem-solving (Junior)
Develop algebra, geometry, combinatorics, and number theory with guided prep for JMC, Kangaroo, and AMC 8/10.
- Intermediate
Competitions (Intermediate)
Strengthen technique and exam strategy for Cayley, IMC, and AIME while improving school and entrance outcomes.
- Senior
Olympiad & university (Senior)
Prepare for National Olympiads, BMO, and STEP/TMUA with advanced training for competitive maths and CS admissions.
One learning path, tailored locally: we align every stage to your country's exam boards, school-year calendar, and competition track.
See where your child fits
Our Olympiad approach helps students get into top schools, win competitions, excel in exams, and progress to leading universities

- 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.
- Learning can take place at your own pace. We will select a convenient schedule and at any time we will help you change the schedule, take a break or adjust the programme.
- All classes last 1 hour.
