How do you get into Chesham Grammar?
Chesham Grammar School is a co-educational grammar school in Chesham, Buckinghamshire, for ages 11–18. Competition for places is strong: only 186 children are admitted to Year 7 each year, selected through the The Buckinghamshire Grammar Schools. Because places are decided mainly on the test score, focused preparation makes a real difference.
Think Smart Academy has been preparing children for the 11+ for over a decade. Our High Wycombe centre prepares Chesham Grammar applicants for the Bucks Secondary Transfer Test. We teach Maths, English, Verbal Reasoning and Non-Verbal Reasoning in separate sessions rather than rushed combined lessons, and track progress with termly mock exams and parent reports. Classes are capped at eight students, and every child starts with a free diagnostic assessment so we can see where they need the most work.
