One-to-one preparation for the school’s 75-minute computer-based Quest assessment, sat on 26 November 2026 for September 2027 entry.
Book a Free ConsultationMy son was low in confidence after COVID and the gaps in learning were building up. Using this service helped plug those gaps, rebuild confidence, and improve his ability to learn properly again.
We arranged maths and English tuition ahead of GCSEs and both tutors were brilliant. My daughter's grades improved, and by results day she achieved two grades higher than in her mock exams.
I attended an English bootcamp with Leading Tuition and the experience was excellent. The teacher gave focused attention to the small group while keeping the lessons interactive and engaging.
Ewell Castle School is a co-educational independent school in Ewell, Surrey, whose 11+ entrance assessment is a computer-based Quest sitting of four sections in 75 minutes: English, verbal reasoning, maths, and puzzles and problem solving. Leading Tuition prepares candidates one to one for that assessment, on screen, against the 26 November 2026 sitting. Only maths and verbal reasoning adapt in difficulty. There is no non-verbal reasoning section and no written paper.
Ewell Castle School's own admissions page does not describe an entrance paper. Its admissions and entry process page links out instead, under the heading Quest Online Assessments, to a page Quest Assessments publishes for this school alone. That page is the specification our tutors work from, and it says something quite different from most of what is written about Ewell Castle elsewhere: the assessment is computer-based, it runs to 75 minutes in total, and it is divided into four timed sections.
Those sections are English at 30 minutes, verbal reasoning at 10 minutes, maths at 20 minutes, and puzzles and problem solving at 15 minutes. Questions are largely multiple choice and require no typing or keyboard skill. Maths and verbal reasoning adapt in difficulty according to how the candidate is answering; English and puzzles and problem solving are fixed. Quest states that its assessments are used by 160+ independent and grammar schools, so the platform is familiar even where this particular arrangement of it is not.
Three things follow, and each one changes what tuition should be doing.
It is not a school-set written paper. There is no long comprehension to write out by hand and no non-calculator arithmetic paper to work through on paper. A programme built around timed written practice trains a skill the candidate will not be asked to use on the day.
It is not the ISEB Common Pre-Test. The ISEB Pre-Tests, on the board's own account, are four shared online subjects covering mathematics, English, verbal reasoning and non-verbal reasoning, sat once and reported to every senior school a family applies to. Ewell Castle's assessment contains no non-verbal reasoning at all, and its result goes to one school.
It is not the two-part Quest used by the London consortium schools. Several independent schools run Quest as an adaptive first part followed by a separate creative comprehension and creative writing component. Ewell Castle, on its published guidance, does not. We cover the two-part arrangement in detail on our Quest assessment tuition hub; it is the wrong preparation for this school.
We say this plainly because the search results for this school do not. Of the five pages Google UK ranked highest for Ewell Castle School 11 plus tutor when we checked in August 2026, two describe the entrance test as a written English and mathematics paper set by the school, one of those adding a standardised reading test from a different provider entirely. One names the assessment correctly but gives no timings. None of the five publishes the section structure a child will actually meet. A family who buys preparation on that basis is buying practice for an exam Ewell Castle does not set.
The total is short. That is the first thing to absorb, because it is the opposite of what most 11+ preparation assumes. A single written entrance paper often runs longer on its own than Ewell Castle's entire assessment, and the pacing habits that suit a long paper — read everything, plan, come back to the hard ones — do not transfer to a section that closes after 10 minutes.
The table below is how we brief a tutor before the first session. It is not a summary of the format; it is the teaching consequence of each line of it.
| Section | Time | Adapts? | What our teaching does about it |
|---|---|---|---|
| English | 30 minutes | No — fixed difficulty | The largest single block, and the one where a strong reader can bank marks. We work on reading a passage once, properly, and answering from it rather than from memory — inference, word meaning in context, and the grammar and punctuation items that sit alongside comprehension. |
| Verbal reasoning | 10 minutes | Yes | The shortest section on the paper and the one most sensitive to hesitation. We build recognition of question types to the point of automaticity, so that the decision is which method, not whether the child has seen this before. |
| Maths | 20 minutes | Yes | Accuracy before speed, deliberately, because difficulty follows the answers. We tighten mental arithmetic and number sense first, and only then compress the clock. |
| Puzzles and problem solving | 15 minutes | No — fixed difficulty | The section with no school syllabus behind it. We teach it as a set of approaches — work backwards, test a case, find the constraint — rather than as content to be revised. |
Read down the middle column and the shape of the assessment is clear. English carries 30 of the 75 minutes; verbal reasoning carries 10. A child who is a fluent reader and a hesitant reasoner, and a child who is the reverse, need genuinely different programmes, and the first thing we do is establish which one is sitting in front of us.
There are no past papers for this assessment. There cannot be: two of the four sections draw from an item bank that responds to the candidate's answers, so no two children sit quite the same test. What Quest publishes instead is a familiarisation test for Ewell Castle School specifically, showing the style of question a candidate will meet.
We use that familiarisation test once, early, and we use it to watch rather than to score. How does the child behave when a question is harder than the one before it? Do they slow down, guess, or freeze? On an adaptive section that behaviour matters more than the mark, because the difficulty of every subsequent question follows from it. A run of confident correct answers pulls the child upward into harder material; a run of hurried guesses does the reverse, and the child spends the rest of the section answering questions well below their level.
So the teaching order is deliberate and it runs against instinct. We do not start with timed practice. We start by making the underlying skill secure at a level above where the child currently answers comfortably, then introduce the clock, then introduce the clock and a screen together. Compressing a shaky skill produces a fast, wrong answer, which on an adaptive section is worse than a slow one.
The fixed sections are handled the other way round. English and puzzles do not respond to performance, so pacing can be practised from the start: 30 minutes for the comprehension, 15 for the puzzles, and a sense of what a third of the way through ought to look like.
Not sure which sections your child would struggle with? The first session of an Ewell Castle programme is a diagnostic across all four — English, verbal reasoning, maths, and puzzles and problem solving — and you get a written summary of where the gaps are before you commit to anything further.
Book a Free Consultation Message us on WhatsAppFifteen of the 75 minutes go on a section that appears on no primary curriculum, in no standard 11+ syllabus, and in none of the four ISEB Pre-Test subjects. It is also the section most commonly missing from what is written about this school. That combination makes it, in our experience, the most efficient place to spend early tuition time: it is unfamiliar to almost every candidate, which means the gains from a few weeks of structured work are larger there than anywhere else on the assessment.
It cannot be revised, because there is no body of content to revise. What can be taught is a small repertoire of moves that solve most puzzles of this kind: work backwards from the required answer; test the smallest case and look for the pattern; identify the single constraint that fixes everything else; check whether the question is really asking for a count, an order, or a rule. We teach these explicitly, name them, and then have the child say aloud which one they are reaching for. Naming the move is what makes it available under a clock.
Because this section is fixed difficulty rather than adaptive, every candidate sees the same demand, and a child who has practised the moves is at a straightforward advantage over one who has not.
Ewell Castle sets one assessment date. For September 2027 entry the 11+ entrance assessment is on 26 November 2026, with a reserve day on 27 November 2026 and outcome letters sent by Christmas 2026. Applications close on 30 October 2026. Because the date is fixed rather than a window, programme length is a real arithmetic question rather than a guess.
Three shapes cover most families:
Whatever the length, the structure is the same. Session one is the diagnostic described above and produces a written plan naming the sections to prioritise. Sessions then run weekly, one to one, with short between-session work rather than long papers. From roughly six weeks out we move to on-screen practice under section timings, because the mechanics of answering with a mouse on a laptop are themselves a skill and should not be met for the first time on 26 November.
The final two sessions are deliberately light. Reviewing the moves, checking that the child knows what the four sections are and in what order, and rehearsing what to do when a question is unreadable — which, on an adaptive section, it eventually will be.
If you are still in Year 4 or early Year 5 and wondering whether it is too early to do anything at all, our Quest preparation timeline for Years 4 and 5 sets out what is worth doing at that stage and what is not.
Ewell Castle candidates are matched to tutors from our 11+ team who already teach Quest-format assessments, not to a general primary tutor with an 11+ workbook. That distinction matters more here than it does for a school with a conventional written paper, because half the job is medium rather than content: the tutor needs to be running the session on screen, sharing a timer, and watching what the child does when the difficulty steps up.
Sessions are one to one and online by default. That is not a cost decision. It is that the assessment is computer-based, so an online session rehearses the conditions of the day rather than working against them: the child reads from a screen, answers with a mouse, and gets used to a question appearing without the reassurance of seeing the rest of the paper around it. In-person tuition is available where a family wants it and we will arrange it, but we will also tell you that screen time is part of the preparation.
Matching is done after the consultation, not before, so that the tutor is chosen against the diagnostic rather than against availability. If the match is wrong — and occasionally it is, usually for reasons of personality rather than subject — we change the tutor without a fuss and without restarting the programme. Ewell Castle is a co-educational through school for children aged 4 to 18 that describes itself in terms of small class sizes and a personalised approach; families drawn to it tend to want the same from a tutor, and we weigh that when matching.
Very few families in this part of Surrey are applying to one school. Ewell sits within reach of selective state schools in Sutton and Kingston, which run their own tests on their own dates, and of a number of independent schools that use the ISEB Common Pre-Test. Those are three unrelated assessments, and the scheduling matters as much as the teaching.
What overlaps: English comprehension, mathematics to the Year 5 curriculum, and verbal reasoning question types are common ground across all three. A child preparing well for Ewell Castle is not starting from zero anywhere else.
What does not overlap: non-verbal reasoning appears in the ISEB Pre-Tests and in the Sutton and Kingston selection tests, and not at all in Ewell Castle's assessment. Puzzles and problem solving runs the other way — it is on Ewell Castle's assessment and on none of the others. And the calendars are different in kind: ISEB testing for the 2026-27 session opens on 1st September 2026 and runs into the following summer, so a family can choose their week, while Ewell Castle has a single date in November. Dunottar School in Reigate works the same way, on Saturday 7 November 2026, which for some families in this part of Surrey puts two fixed assessment days within three weeks of each other.
In practice that usually means front-loading the shared skills, then splitting the last two months by assessment. We work this out at the consultation rather than selling two programmes. Our page on Quest versus the ISEB Common Pre-Test sets out the format differences in full, and for the state selective route in this area, Sutton 11+ tuition covers the tests those schools actually use. Families weighing a nearby independent alternative often look at Surbiton High School at the same time; and if the plan is deferred entry at 13+ rather than 11+, the ISEB pre-test page is the better starting point.
We are rated Excellent on Trustpilot, 4.8 out of 5 from 54 reviews, and 91% of our students achieve their desired grades. Those are practice-wide figures across every level we teach, not a Ewell Castle-specific cohort — we do not publish a school-by-school pass rate, because we do not hold one we could evidence.
No. The school's admissions page directs families to Quest, whose guidance for Ewell Castle states that the assessment is computer-based: four sections over 75 minutes, comprising English at 30 minutes, verbal reasoning at 10, maths at 20, and puzzles and problem solving at 15. Questions are largely multiple choice and require no typing or keyboard skills. Several tutoring pages that rank well for this school still describe a handwritten English and mathematics paper; that description does not match the school's own published guidance for September 2027 entry, and preparation built on it is aimed at the wrong assessment.
Maths and verbal reasoning adapt in difficulty according to how the candidate answers. English and puzzles and problem solving are fixed difficulty, so every candidate meets the same demand in those two sections. The practical consequence is that accuracy early in the adaptive sections matters disproportionately: a run of hurried guesses pulls the difficulty down and the child spends the remainder of the section below their real level. That is why our programmes build the underlying skill first and only introduce the clock once answers are reliable.
No, and any site selling them is selling something else. Two of the four sections draw adaptively from an item bank, so no two candidates sit an identical test and there is nothing to release. Quest publishes a familiarisation test for Ewell Castle School showing the style of questions a child will meet, and we use it once and early, to watch how a child behaves when questions get harder rather than to generate a score. The rest of the preparation is built from the published section specification, not from reconstructed papers.
September of Year 6 gives roughly fourteen weeks and suits most candidates. Starting in the spring or summer term of Year 5 is the better choice where reading is still developing, because reading age moves slowly and English carries 30 of the 75 minutes. Beginning after October half term is possible but should be understood as familiarisation and pacing rather than skill-building. Whichever start you choose, the application itself must be in by 30 October 2026, and the reserve assessment day is 27 November 2026.
The school does not publish one, and we will not invent one. No score threshold, standardised-score cut-off or historic pass mark appears on Ewell Castle's admissions pages or on the Quest guidance the school links to, and outcome letters are sent by Christmas 2026 after the whole cohort has been assessed. Anyone quoting a required score for this school is estimating. What we can plan against is the format and the section timings, which are published, and the diagnostic tells us where a particular child sits relative to the demand of each section.
It is the same provider, used by 160+ independent and grammar schools, but not the same arrangement. Several London independent schools run Quest as an adaptive first part followed by a separate creative comprehension and creative writing component, and some grammar school consortia use a paper-based Quest test with non-verbal reasoning. Ewell Castle's published arrangement is a single 75-minute computer-based sitting of four sections with no non-verbal reasoning and no creative writing component. Preparation written for those other arrangements does not transfer cleanly.
No. Ewell Castle states that all candidates are assessed for an academic scholarship within the entrance assessments, so there is no separate academic paper and no additional sitting. A scholarship hopeful prepares for the same four sections in the same 75 minutes as every other candidate. Awards in art, dance, design and technology, drama, music and sport are applied for separately, with a portfolio where one is required, and are not academic assessments. We will say if we think a family is being sold preparation for something that does not exist.
