The curriculum leans towards the academic mainstays: maths, the three separate sciences, English and the humanities feature prominently at both GCSE and A-level, alongside popular options such as Psychology, Economics and Government and Politics. French, German and Spanish are taught, and the EPQ is available to stretch sixth-formers beyond the standard syllabus.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A historic, fully Outstanding grammar where consistently strong results meet a serious academic ethos. A genuine state-school alternative to fee-paying education for capable girls.
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.
