The Royal Grammar School, High Wycombe has its own admissions pattern, and the right preparation follows it exactly. This guide walks through the test the school selects on, how that test is scored, a realistic Year 4 to Year 6 build-up, and the free practice that matches every part of it. Because RGS is one of the most heavily over-subscribed boys' grammars in the country, the difference between a place and a near-miss is usually made in the last third of a timed paper, so the plan below is built around pace and composure as much as content.
About The Royal Grammar School, High Wycombe
Royal Grammar High Wycombe, almost always shortened to RGS, is a foundation grammar for boys with a mixed sixth form. It was granted its 'Royal' title by Elizabeth I in 1562, which makes it one of the oldest schools in the country still selecting by examination. Selection is by the Buckinghamshire Secondary Transfer Test, the shared county test sat by children hoping for any of the thirteen state grammar schools in Buckinghamshire. That shared-test arrangement matters for parents: you are not preparing for a private RGS paper, you are preparing for the same county exam that decides entry across the whole of Bucks.
- Location: High Wycombe, Buckinghamshire

How selection works at The Royal Grammar School, High Wycombe
RGS does not set its own private paper. Like every state grammar in the county, it admits on the results of the county-wide Buckinghamshire Secondary Transfer Test, which is administered by the Buckinghamshire Grammar Schools group. Children sit it in mid-September of Year 6, right at the start of the autumn term, which means the real preparation window closes over the summer holiday before that — a crucial detail, because it puts the hardest revision squarely inside the long break rather than in a busy term.
The test assesses three areas: verbal reasoning, non-verbal reasoning and numerical reasoning (maths). In practice these are grouped into two papers — an English and verbal reasoning paper, and a maths and non-verbal/spatial reasoning paper — delivered across two sittings a few days apart, each made up of separately timed sections, with answers recorded on a multiple-choice answer sheet read by machine. It is a familiarisation-supported test: an official practice booklet and sample questions are published each year so that no child walks in cold. There is no English comprehension essay and no creative-writing task in the Bucks test, which is one way it differs from written-answer exams such as the Essex CSSE elsewhere in the country.
A quick note on exam boards, because this is where a lot of older online guidance is now wrong. The Bucks test is a GL Assessment test today, and while it grew out of the CEM style once run from Durham University, CEM's separate paper 11+ was discontinued around 2022 to 2023. The current test keeps some of that spirit — broad vocabulary, mixed sections, tight timing that rewards steady speed over pure question-type memorisation — but you should always confirm the exact current format on the school's site and the official Bucks familiarisation materials rather than trust dated forum posts.
Selection is by standardised score, which is age-adjusted so that a summer-born child is not penalised for being nearly a year younger than an autumn-born classmate sitting the same paper. Two boys with the same raw mark can therefore end up with different standardised scores purely because of their month of birth. In Buckinghamshire a qualifying standardised score of around 121 is generally treated as the pass mark, but qualifying is not the same as securing a place: RGS is so over-subscribed that meeting the threshold puts a boy into the admissions process, after which distance and the school's published oversubscription criteria decide who is offered a place. We will not quote a specific catchment cut-off, because it moves year to year — check the official policy.
What to practise for this test
Because the Bucks test is reasoning-heavy, your practice should be weighted towards verbal and non-verbal reasoning, with maths kept sharp alongside. Here is how the three areas break down and where to drill each one for free:
- Verbal reasoning: the widest single area, covering codes, letter and number sequences, hidden words, analogies, odd-one-out, closest-meaning and opposites, and compound words. Vocabulary is the biggest lever here — a boy who reads widely simply meets fewer unfamiliar words under time pressure. Drill the named question types on our free worksheet library and full GL-style reasoning papers.
- Non-verbal reasoning: series, matrices, analogies, odd-one-out, reflections, rotations and spatial folding such as cube nets. These reward exposure: the more patterns a child has seen, the faster they spot the rule. Work through the NVR sets in the same worksheet library.
- Numerical reasoning (maths): KS2 maths up to roughly the Year 5 curriculum ceiling, applied at speed — times tables to 12×12, fractions, percentages, ratio and multi-step word problems. Fluency with tables underpins almost everything else, because slow arithmetic quietly steals the time a boy needs for the harder questions.
Once individual skills are solid, move to whole timed papers so the child practises switching between sections without losing rhythm. Our free mock papers reproduce the multiple-choice, separately-timed structure, and the centre-specific mocks let you rehearse in a format close to the real Bucks sitting. You can also build wider technique on our revision hub. No account is needed to start practising.
A realistic preparation timeline
There are no shortcuts, but there is a sensible order. Avoid heavy formal papers too early; build the foundations first and let confidence, not panic, do the work.
- Year 4 into the summer: daily independent reading and a solid grip on times tables to 12×12. No timed papers yet — this is about vocabulary and number confidence.
- Year 5 autumn: begin 15 to 20 minutes of daily topic practice using the free worksheets, rotating through VR, NVR and maths so nothing goes stale.
- Year 5 spring — register: Buckinghamshire registration typically opens in the spring and closes before the summer. Confirm the exact window on the school's site and our key dates page; missing it means missing the test entirely, and there is no late route.
- Year 5 summer holiday: the crucial block. One full timed mock a week, reviewing every error more carefully than the score itself.
- Final weeks before mid-September: switch to centre-specific papers in the Bucks format and taper the volume so your child arrives fresh, not exhausted.
On the day and after
By September the content work is done; the test-day job is composure. A boy who has sat ten timed mocks at the kitchen table treats the real hall as the eleventh. Keep the night before ordinary — normal bedtime, familiar breakfast, no last-minute cramming. Remind him of the mechanics he already knows: read each instruction, keep moving, mark a best guess rather than stalling on a hard question, check the answer-sheet row matches the question number, and use the fact that there is no penalty for a wrong answer on a multiple-choice sheet. Afterwards, let it go. Results usually arrive in October, and whatever they say, the reading, number fluency and calm-under-pressure he has built are worth having regardless of the outcome.
Frequently asked questions
Does The Royal Grammar School, High Wycombe set its own entrance exam?
No. RGS admits on the county-wide Buckinghamshire Secondary Transfer Test, the same test used by all thirteen Bucks state grammars, rather than a private school paper.
What subjects does the Bucks test cover?
Verbal reasoning, non-verbal reasoning and numerical reasoning (maths), split across two papers. There is no separate English comprehension essay or creative-writing task, so preparation should be weighted towards reasoning and speedy, accurate maths.
What score is needed to pass in Buckinghamshire?
A qualifying standardised score of around 121 is generally treated as the threshold, and scores are age-adjusted for month of birth. Passing qualifies a child for the admissions process; because RGS is heavily over-subscribed, a place then depends on distance and the school's published criteria. Always confirm current figures with the school and the county.
