Your child's personalised training system
Every Exact Science student trains on Problems.cc — our interactive problem platform. It turns lessons into a structured, data-informed practice system so you and your child can see real progress.
- Tracks mistakes across topics, not just scores on single tests.
- Recommends next problems at the right difficulty, based on previous work.
- Shows progress through levels so students can see how far they have come.
- Supports competitions worldwide with problem sets aligned to international Olympiad-style contests.
The platform is built to work internationally: we can adapt topics, language, and contest preparation to different countries while keeping the same core training principles.

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.
- 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.
