Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A high-achieving girls' school where strong science and maths results sit alongside an 'excellent' inspection verdict. Means-tested bursaries, a hardship fund and academic scholarships help widen access beyond the day fees.
That’s where Passmate comes in. Tutoring is the most effective thing in a child’s preparation - a well-tutored child can outperform the vast majority of their peers. Passmate works alongside your tutor, not instead of them: it learns how your child thinks, finds the gaps, and shows the tutor exactly where to spend each session - so the limited time you have lands on what actually decides a place.
