Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
An Outstanding co-educational Catholic grammar with results among the strongest you will find. Families drawn to its faith ethos and academic ambition should expect serious competition for its 150 places.
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.
Works alongside your child’s tutor - not instead of them.
