A large, oversubscribed grammar school in Slough, Burnham Grammar currently teaches around 1,271 pupils against a capacity of 1,078 - a sign of how keenly its places are sought.

Teaching & academics
Results sit well above national norms: an average Attainment 8 score of 70.1 compares with a national figure of 46.9, and 94% of pupils secure grade 5 or above in English and Maths against a national 47%. These are the kind of outcomes that confirm the school's academic selectivity is matched by what happens in the classroom. Entry is assessed by GL Assessment papers in Maths, Verbal Reasoning and Non-Verbal Reasoning, so preparation should cover all three confidently.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A strongly performing, heavily oversubscribed mixed grammar where high attainment and a genuinely diverse pupil body go hand in hand. Families should prepare thoroughly for the GL consortium assessment, as competition for its 180 places is real.
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.
