Rainham Mark Grammar School
School summary
A large Kent grammar school in Gillingham, Rainham Mark currently educates around 1,551 pupils, comfortably beyond its formal capacity of 1,242 - a sign of how sought-after places here have become. Entry at 11 is via the Medway Test, and with 235 places on offer against strong demand, competition is real.

The intake reflects its local community, with around one in ten pupils eligible for free school meals.
How hard is it to get in?
Moderate · 1 of 5 on the Passmate scale. Entry is selective, but demand for the 235 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 consistently high-performing Medway grammar where strong results meet solid Good ratings throughout. Families should be prepared for genuinely competitive entry via the Medway Test.
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.
