11 Plus Tutoring in South London: Wilson’s, Sutton Grammar & Nonsuch Preparation

South London has some of the most competitive state grammar schools in England. Wilson’s School, Sutton Grammar School, and Nonsuch High School for Girls all sit within the London Borough of Sutton — and all three consistently rank among the top-performing schools in the country. For families across South London, the 11 Plus is a high-stakes exam that requires proper preparation.

This guide covers how the 11 Plus works for the Sutton grammar schools, what preparation actually looks like, and how StudyBox’s centres in Wallington, Sutton, and Croydon help children prepare effectively.

The South London Grammar Schools: What You’re Aiming For

Wilson’s School

Wilson’s School in Wallington is a boys’ selective grammar school and one of the most oversubscribed in London. It consistently achieves exceptional GCSE and A Level results and is rated Outstanding by Ofsted. Entry is via the Sutton Consortium 11 Plus test — a highly competitive process with far more applicants than available places.

Sutton Grammar School

Sutton Grammar School is a boys’ school in the centre of Sutton, offering a rigorous academic environment and strong sixth form provision. Like Wilson’s, it is part of the Sutton Selective Eligibility Test (SET) administered by the Consortium. Entry is extremely competitive and applications come from across South London and beyond.

Nonsuch High School for Girls

Nonsuch High School for Girls is a selective grammar in Cheam, serving girls from Year 7 to Year 13. It is consistently rated Outstanding and achieves some of the best results in Surrey and South London. Entry is also through the Sutton Consortium test.

Other Local Grammar Schools

Wallington County Grammar School for Boys and Wallington High School for Girls also use the Sutton Consortium test. Together, these five schools form a cluster that makes the Sutton area one of the most grammar-dense postcodes in London. Many Croydon and South Croydon families target all five as part of their 11 Plus strategy.

How the 11 Plus Works for the Sutton Consortium

The Sutton schools use the GL Assessment 11 Plus, which tests four areas:

  • Verbal Reasoning — word relationships, analogies, codes, and language logic
  • Non-Verbal Reasoning — visual patterns, sequences, and spatial logic
  • English — reading comprehension, grammar, vocabulary, and spelling
  • Mathematics — problem-solving and numerical reasoning at an accelerated level

The exam is typically taken in September of Year 6, meaning preparation needs to begin by Year 4 or 5 at the latest. The tests are designed to assess potential as well as taught knowledge, but in practice, children who have practised extensively with past papers and timed conditions significantly outperform those who haven’t.

What 11 Plus Preparation Actually Involves

A common misconception is that the 11 Plus can be crammed in the summer before the exam. In reality, effective preparation for Wilson’s, Sutton Grammar, and Nonsuch typically spans 12 to 18 months — not because the content is impossibly difficult, but because the skills tested (speed, accuracy, pattern recognition under pressure) take consistent practice to develop.

Effective 11 Plus preparation has three stages:

Stage 1: Foundation (Year 4 – early Year 5)

Building fluency in core maths (times tables, fractions, mental arithmetic) and English (vocabulary, comprehension, grammar). At this stage the focus is on curriculum mastery and closing any gaps before the 11 Plus-specific content begins.

Stage 2: 11 Plus Skills (mid Year 5)

Introduction to verbal and non-verbal reasoning. This content is not typically taught in primary school, so children need explicit instruction. The maths element extends beyond the KS2 curriculum into multi-step problem-solving and numerical reasoning formats.

Stage 3: Exam Preparation (Year 6)

Timed past paper practice under exam conditions, with detailed review of errors. Speed is as important as accuracy — children need to work quickly and strategically, skipping and returning to difficult questions rather than stalling.

11 Plus Tutoring at StudyBox

StudyBox has three centres within easy reach of the Sutton grammar schools — in Wallington, Sutton, and Croydon. All three offer dedicated 11 Plus preparation sessions for children in Year 4, 5, and 6.

How Our 11 Plus Sessions Work

11 Plus sessions at StudyBox run for 2 hours and are taught in small groups of no more than 3 students per tutor. The structured format covers:

  • Maths — curriculum extension beyond KS2, multi-step problems, mental arithmetic speed work
  • Verbal Reasoning — systematic introduction to all VR question types: analogies, codes, letter sequences, word relationships
  • Non-Verbal Reasoning — visual pattern sequences, matrix completion, spatial reasoning
  • English — comprehension techniques, extended vocabulary, grammar under timed conditions
  • Past paper practice — timed, marked, reviewed. Children learn to manage time across a full paper and identify which question types to prioritise

Pricing

11 Plus sessions at StudyBox are £60 for a 2-hour session — small group, maximum 3 students. If you use Tax-Free Childcare, government top-up reduces the effective cost by 20% to £48 per session.

Which Centre is Closest to You?

All three StudyBox centres offer 11 Plus preparation:

  • Wallington — Unit 1, Kensington Court, 108 Manor Road, SM6 0DW (closest to Wilson’s School, Wallington County Grammar)
  • Sutton — Unit 2, 5 Robin Hood Lane, SM1 2SW (closest to Sutton Grammar School, Nonsuch)
  • Croydon — 305–309 Brighton Road, South Croydon, CR2 6EQ (serving South Croydon, Purley, and surrounding CR2/CR8 areas)

When Should You Start?

The most common question from parents is: when is it too early to start?

The honest answer is that starting in Year 4 is ideal. This gives time to build solid foundations in maths and English before introducing 11 Plus-specific content in Year 5. Children who begin in Year 6 can still succeed, but they’ll need to work intensively — which adds pressure at an already busy time.

If your child is already in Year 6, it’s not too late — but it’s worth booking a trial session as soon as possible so we can assess where they are and design a realistic programme for the time available.
