Families targeting John Hampden Grammar School ask the same first question: what exactly should we practise? Here is the school-specific answer, built around how this particular boys' grammar in High Wycombe actually selects its Year 7 intake. Because entry depends on a single county-wide test sat in mid-September of Year 6, your preparation should be shaped by that test's subjects, timing and answer format rather than by generic 11+ advice. Everything you need to follow this plan is free on Quest Arena, with no account required to start practising.
About John Hampden Grammar School
John Hampden is High Wycombe's second boys' grammar, sitting in the south of the town. It is a well-established Foundation grammar with a long history, and selection is by the Buckinghamshire Secondary Transfer Test taken across the whole county. Like the other state grammars in Buckinghamshire, it does not run its own separate entrance paper: your son sits one shared county test, and the resulting standardised score is used across all the grammars you name on your application. That is an important point to grasp early, because it means preparing for John Hampden is really preparing for one county-wide test rather than for a bespoke school paper. Buckinghamshire runs thirteen state grammars in total, so a boy who qualifies has genuine choice, and your job as a parent is to make sure the qualifying score is comfortably within reach.

You can see our full school profile for John Hampden, and browse the other Buckinghamshire grammars in our grammar school directory. For the definitive admissions timeline, open days and the current year's arrangements, always check the school's own site: jhgs.bucks.sch.uk. A school website is the single most reliable source for dates and oversubscription rules, which is why it is the authority we point you to for anything that can change year to year.
How selection works at John Hampden Grammar School
Admission is decided by the Buckinghamshire Secondary Transfer Test, the single test used by every state grammar in the county. Historically this test was designed by CEM (the Durham University assessment centre), and older guides still describe it that way. It is worth being clear about the current position: CEM's separate paper 11+ tests were largely phased out around 2022–2023, so if you read older forum posts referring to a "CEM Bucks test", treat the format details as a guide rather than gospel and confirm the current arrangements with the school and Buckinghamshire Council each year.
What has stayed consistent is what the test measures and how it is structured. The Bucks Secondary Transfer Test is delivered across two papers taken on the same morning. Paper 1 combines English and Verbal Reasoning; Paper 2 combines Maths and Non-Verbal (spatial) Reasoning. Both are multiple-choice with tightly, separately-timed sub-sections, and answers are marked on a separate answer sheet rather than in the booklet — a mechanical detail worth rehearsing so it never costs marks on the day. Because each sub-section is timed on its own, a boy cannot borrow spare minutes from an easy section to rescue a hard one; pacing has to be right first time.
Scores are age-standardised, meaning a summer-born child sitting the same paper as an older classmate receives an uplift so that younger pupils are not disadvantaged by their birth month. To make that concrete: two boys might each get the same raw number of questions right, but a September-born child and a July-born child will convert that raw mark to slightly different standardised scores, with the younger boy nudged upward. The qualifying standard used in Buckinghamshire is a standardised score of 121. Reaching that qualifying score means your son is deemed selective; it does not by itself guarantee a place at John Hampden specifically, because place allocation then depends on the school's oversubscription criteria such as distance and catchment. Never rely on an invented cut-off beyond the published county qualifying score.

What to practise for this test
Because the test rewards familiarity with question types and speed under pressure, focus your practice on the assessed areas and drill them until the formats feel automatic. Aim for accuracy first and speed second — a boy who is confident with each format will naturally get faster, whereas one who is rushing an unfamiliar layout simply makes more mistakes.
- English & comprehension: reading a passage closely, answering inference and vocabulary questions, and spotting spelling, punctuation and grammar errors at pace. Wide daily reading is the foundation here, and it feeds straight into the verbal reasoning section too.
- Verbal Reasoning: codes, letter sequences, hidden words, analogies, odd-one-out, closest-meaning and opposites, compound words, move-a-letter and number series. Vocabulary is the single biggest driver of the score, so pair drills with wide reading rather than treating them as separate jobs.
- Non-Verbal & Spatial Reasoning: series, matrices, analogies, odd-one-out, reflections, rotations, cube nets and spatial folding. These sit outside the normal school curriculum, so most of the gains come from simply seeing enough examples until the visual patterns become obvious.
- Maths: the KS2 syllabus up to Year 5 level — number, fractions, ratio, measure and problem-solving — done at pace and without a calculator. Fluent times tables underpin almost every question, so they are the highest-value early investment.
Start with our free worksheet library to build accuracy topic by topic, then move to full-length timed papers in our mock papers hub. As the test approaches, switch to centre-specific mocks matched to the Buckinghamshire format so the timing and answer sheet feel routine. Our GL-style practice papers are a good match for the multiple-choice, separately-timed structure Bucks now uses, and the revision hub pulls the weakest topics together. If you want to walk through the wider admissions process step by step, our 11+ process guide lays it out plainly.
A realistic preparation timeline
Steady, early exposure beats a last-minute cram. There are no fixed private dates to hit beyond the county registration window and the mid-September test, so build habits first and add timed papers later. The goal across the three years is to make the September test morning feel like just another practice session your son has already sat many times.
- Year 4: daily reading for pleasure and times tables to 12×12. No formal papers yet — just confidence with number and words, and a habit of reading a little every day.
- Year 5 autumn: begin 15–20 minutes of daily topic practice using our free worksheets, introducing one reasoning type at a time so nothing feels overwhelming.
- Year 5 spring and summer: register for the test in the county window (check the school site and our key dates page), and start one full timed mock a week. Review errors far more carefully than the raw score — the mistakes are where the marks live.
- Year 6, first weeks: the test falls in mid-September, so the final six weeks over summer are for centre-format papers, sharpening pace and marking answers on a separate sheet under strict time limits.
Keep the workload sustainable. Two or three short focused sessions a week, done consistently across two years, achieve far more than an anxious daily slog in the final term. If a topic is clearly a weakness, spend a week on it and then move on; there is no need to master everything at once when there is time to circle back.
On the day and after
By test morning the work is done; the job now is composure. A child who has sat ten timed mocks at the kitchen table treats the real hall as the eleventh. Keep the night before calm, get a proper sleep, and eat a normal breakfast. Remind your son of the practical mechanics he already knows: read each instruction, keep moving, mark answers cleanly on the separate sheet, and never spend too long on one question — in a tightly timed multiple-choice paper an educated guess and a move-on beats a stall. Afterwards, resist the urge to interrogate every answer. Results are issued to families before the secondary application deadline, so once the test is sat, focus on completing your school preferences on the common application form and let the process run. Naming John Hampden alongside your other genuine preferences, in true order, is the right approach.
Frequently asked questions
Is the John Hampden test GL or CEM?
The Buckinghamshire Secondary Transfer Test was historically CEM-designed, but CEM's separate 11+ was largely phased out around 2022–2023 and the county test is now provided by GL Assessment as a multiple-choice, separately-timed format. Confirm the current provider with the school and Buckinghamshire Council for your test year.
What score does my son need to pass in Bucks?
The county qualifying standard is an age-standardised score of 121. Meeting it makes a child selective, but a place at John Hampden then depends on the school's oversubscription criteria, such as distance.
Does the test include verbal reasoning?
Yes. The Bucks test assesses English, Verbal Reasoning, Non-Verbal (spatial) Reasoning and Maths. Verbal Reasoning and vocabulary carry a lot of weight, which is why wide daily reading matters as much as drilling question types.
