11 Plus Maths Tuition Slough | Consortium 11+ Maths Online

In short

Slough's four grammar schools, Herschel, Langley, St Bernard's Catholic and Upton Court, share one 11+ examination run by the Slough Consortium of Grammar Schools, independently of Slough Borough Council. Families register once, free of charge. The consortium describes two multiple-choice papers of 60 to 65 minutes, one covering maths and non-verbal reasoning and the other verbal skills, with no negative marking and rough work allowed. A standardised score of 111 or above, which the consortium says marks the top 35% of those tested, makes a child eligible to be considered. For September 2027 entry registration ran from 1 May to 5 June 2026 and the test was on Saturday 19 September 2026. From the September 2027 sitting, Quest Assessments replaces GL, with a similar structure and the same 111 line. We teach the maths, live online. The opening lesson is free, and from then on it is USD 100 a month for a group or USD 150 a month one to one.

The consortium exam

What the Slough Consortium publishes

Slough Borough Council says the 11+ is run entirely by the consortium. The consortium's April 2026 briefing answers, published by its schools, are the fullest source. Read on 26 September 2026.

The Slough Consortium 11+ for September 2027 entry, and what is announced for 2028 entry
	September 2027 entry	September 2028 entry
Registration	10am, 1 May to 10am, 5 June 2026	Not yet published
Examination	Saturday 19 September 2026	September 2027
Provider	GL Assessment	Quest Assessments
Format	Two multiple-choice papers, 60 to 65 minutes each	"Similar to those used under the previous provider"
Eligibility score	111 or above	"Will continue to be set at 111"

The briefing describes one paper as covering "Maths and Non-verbal Reasoning" and the other as verbal skills; in answer to a different question it says "Each paper consists of a mixture of the three elements". Either way, maths shares its time with non-verbal reasoning. The consortium does not publish the weighting of the elements or the number of questions, which "may vary from year to year".

Answers go on a separate sheet that is scanned and marked by software. There is no negative marking. Children may use "any white space in the question booklets for rough work and /or the spare paper provided", but must not write notes on the answer sheet.

On practice material the consortium is candid: GL provides familiarisation material showing the question-and-answer format, but GL's other practice papers "are not specifically for the Slough examination". There are no mock tests. For the September 2027 sitting, Quest Assessments takes over, and Herschel Grammar School's page says the structure and format will be similar.

The four grammar schools are the test centres, and the same papers are used in the morning and afternoon sessions at all four. How each school then admits children is set out in its own arrangements, and we do not advise on it.

The 111 line

What "top 35%" means, in plain numbers

The consortium explains its eligibility score more clearly than most, and the explanation is worth understanding, not memorising.

The consortium's own words

"The standardised score has a midpoint of 100. A child scoring 100 is in the middle of the range." And: "The scale is fixed so that a score of 111 means that the child falls in the top 35% of the range. When the results are published, 35% of those taking the test will score 111 or above."

In other words, 111 is not a number of marks. It is a position. However hard or easy a particular year's papers are, the same share of children reaches it.

What follows

Thirty-five per cent is seven in every twenty. If a thousand children sat the test, about 350 would reach 111. A family cannot aim at a raw mark, because nobody outside the provider knows what raw mark will correspond to 111 in a given year.

That is why we never quote targets. What a child can control is how much of the maths they get right, calmly, in the time. The rest is set by everyone else who sits the paper.

The consortium adds that a score of 111 or above "is not an offer of a place and does not guarantee a place". Allocation depends on each school's admission arrangements. That is the schools' business, not ours.

The lesson

The maths of time: watches, minutes and timetables

Time questions test several things at once: reading a clock, adding in base 60, and pulling the right number out of a table. The Year 5 curriculum names each part.

A timetable of our own, used in lessons (not a real service)
Stop	Bus A	Bus B	Bus C
Station	07:48	08:13	08:41
High Street	07:55	08:21	08:49
Park Road	08:06	08:33	09:02
School Lane	08:19	08:47	09:18

Elapsed time

How long does Bus A take from Station to School Lane? From 07:48 to 08:19 is 12 minutes to 08:00 and 19 more: 31 minutes. Counting on through the hour beats subtracting 748 from 819, which gives the wrong answer, 71.

Reading across

A child must be at School Lane by 08:50. Which is the latest bus they can catch from High Street? Bus B, leaving 08:21 and arriving 08:47. Bus C arrives at 09:18.

Comparing journeys

Which bus is slowest from Station to School Lane? A takes 31 minutes, B 34, C 37. The answer needs three elapsed times, each done carefully.

The national curriculum asks Year 5 pupils to "solve problems involving converting between units of time" and to "complete, read and interpret information in tables, including timetables". Both sit inside the questions above. The trap in each is treating times as ordinary decimal numbers: 08:19 minus 07:48 is not 71 minutes, because an hour has 60 minutes, not 100.

We teach counting on through the hour, with a quick sketch of a number line: from 07:48 to 08:00, then from 08:00 to 08:19. It is slower to explain than to do, and it never gives 71.

The watch connects the lesson to the exam room. A 60 to 65 minute paper starting at, say, 09:40 ends at about 10:40 to 10:45. Half-time is around 10:10. A child who can read that from an analogue face at a glance, and knows roughly how far through the booklet they should be, paces without panic.

We practise with an analogue clock face on screen during timed work, so that reading the minute hand becomes automatic. Children who do not wear a watch simply use the room clock the same way.

How we prepare

Unknown question counts, known curriculum

The consortium publishes neither the number of questions nor the weighting of maths. Preparation has to be robust to both.

The whole of Year 5

Number, fractions, measures, geometry and statistics, each taught until quick and correct, because nobody outside the provider knows which will carry most weight.

Pace without a count

When the number of questions is unknown, pacing by time rather than by question number is safer. That is where the watch, or the wall clock, earns its place.

A provider change

For the September 2027 sitting the questions come from Quest instead of GL, in a similar structure. Curriculum-based preparation is untouched by the change.

Familiarisation material from the provider is the right way to see the layout. For the 2027 cycle the schools published GL booklets; for 2028 entry, watch the schools' pages for whatever Quest provides. We do not reproduce either.

Rough work is allowed in the booklet margins and on spare paper, so we teach tidy, short working. It makes checking possible without losing time.

Maths shares a paper with non-verbal reasoning. We teach the maths only; families wanting help with non-verbal reasoning need someone else, and we tell them so at the start.

Every question we use is our own, written to the Year 5 curriculum and the published format: multiple choice, an answer sheet, no negative marking.

Slough and around

Four schools, one exam, lessons at home

The four consortium schools are the test centres. We list them only to show which exam this page covers.

The Slough Consortium of Grammar Schools, as Herschel Grammar School lists it
School	Role on test day
Herschel Grammar School	Test centre
Langley Grammar School	Test centre
St Bernard's Catholic Grammar School	Test centre
Upton Court Grammar School	Test centre

The consortium says families outside Slough, including in Reading, register directly with it, and that its test is its own even though other areas also use GL. The paper is the same whichever centre a child attends.

Reading's two selective schools set their own tests, which are separate from this one; this page is only about the Slough Consortium examination.

Our lessons are live on video, so a child in Langley, Burnham or Cippenham is taught with others at the same level of Year 5 maths, from anywhere, in groups of five to ten.

We have no connection with the consortium, any of its schools or the council, and we do not advise on applications or places.

Timeline

Four stages before the first Quest sitting

For a child now in Year 5, the next consortium exam is in September 2027, early in Year 6, with Quest as the provider.

Building towards a 60 to 65 minute multiple-choice paper
When	Stage	Signs it is done
Autumn, Year 5	1. Number	Tables, place value and mental calculation are fast and dependable
Winter, Year 5	2. Measures and time	Elapsed time and timetables answered without the 71-minute mistake
Spring and summer, Year 5	3. The full curriculum	Fractions, geometry and statistics as secure as number
Summer holiday	4. Paced papers	Uses a watch or clock to pace a full paper and finishes it

A later start

Starting in the spring still works if number comes first and timed papers last.

At the free lesson we will say honestly what the time available can do.

After the results

Time and timetables become speed, distance and rates in secondary school. Some pupils go on to maths through coding and build their own timetable tools.

Keen problem solvers try the national challenges on our competitions calendar.

Slough questions

What Slough families ask us

What is in the Slough 11+?

The consortium describes two multiple-choice papers of 60 to 65 minutes, one covering maths and non-verbal reasoning and the other verbal skills. It does not publish the number of questions or the weighting of each element.

Can my child wear a watch?

The consortium says children can wear an analogue watch if they wish, but no smartwatches. There is also a clock easily visible in the exam room.

What does a score of 111 mean?

The consortium says the standardised score has a midpoint of 100 and that 111 marks the top 35% of those taking the test. A score of 111 or above makes a child eligible to be considered, but is not an offer of a place.

Is there negative marking?

No. The consortium says there is no negative marking.

Is the provider changing?

Yes. Herschel Grammar School says the consortium has contracted Quest Assessments for the examination in September 2027, with a similar structure and format and the eligibility score still set at 111.

When is the next Slough 11+?

September 2027, for September 2028 entry. Exact registration and test dates had not been published when we checked on 26 September 2026. For 2027 entry, registration ran from 1 May to 5 June 2026 and the test was on 19 September 2026.

Are there Slough past papers?

No. The consortium says there are no mock tests or official practice papers, and that GL's general practice papers are not specifically for the Slough examination.

Do you teach non-verbal reasoning?

No, only the maths. We also do not advise on applications or places.

Is registration free?

The consortium says there is no charge for the 11+ test. Families register once for all four schools.

How much are your lessons?

Your first lesson is free. Afterwards, group lessons are USD 100 a month and private lessons USD 150 a month, and you can stop at any point.
