How hard is it to get in?
Moderate · 1 of 5 on the Passmate scale. Entry is selective, but demand for the 120 Year 7 places is more manageable than at most selective schools - a solid qualifying performance is usually what matters.
Where every mark matters.
Places are limited and demand is high, so exam performance is what sets candidates apart. Passmate turns the months ahead into ten focused minutes a day on the exact topics this school tests.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A solidly performing boys' grammar that combines above-average outcomes with an unusually international community. Families seeking selective state education in Boston will find a school rated Good throughout.
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.
