Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A consistently Outstanding grammar with results among the strongest you will find, drawing far more families than its capacity allows. Strong preparation for the GL-assessed consortium exam is essential.
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.
