11+ Maths Tutor in South-East London: A Local Prep Guide

A good 11+ maths tutor in South-East London does two jobs at once: they stretch the arithmetic and reasoning your child's Year 6 classroom does not have time to push, and they prepare your child for the particular selective exam you are aiming at. That second part is where most families go wrong. A Bexley or Kent grammar test and a South-East London independent school's own maths paper are not the same exam, and a tutor who does not know which one you are sitting will teach your child the wrong thing well. The genuinely hard part is not finding someone who can do maths. It is knowing whether the person you found is qualified, safe and actually effective before you hand over your Saturday mornings and your child's confidence. This guide explains what the local 11+ maths exams test, how the routes differ across the South-East London boroughs, and how to check a tutor's credibility instead of trusting a self-written profile.

What "11+ maths" really means in South-East London

South-East London is an unusual patch for selective entry, and it shapes who you should be preparing with. The inner boroughs — Greenwich, Lewisham and Southwark — have very few or no state grammar schools of their own. So families here tend to aim in one of two directions, and often both as a safety net.

The first is the ring of state grammar schools just outside, in Bexley, Bromley and Kent: schools such as Bexley Grammar, Beths Grammar, Chislehurst and Sidcup, Townley Grammar, St Olave's and Newstead Wood. Entry to these runs through borough-wide selective tests. The second direction is the strong set of South-East London independent day schools — Blackheath High, Colfe's, Eltham College, Alleyn's, Dulwich College and James Allen's Girls' School among them — which each set their own entrance papers.

Those two routes test maths differently. A tutor who has only ever prepared children for one of them may still be excellent, but they are not automatically the right fit for the other. The first question to settle, before you look at any tutor, is which schools are realistically on your list. Everything else follows from that.

The two exam routes — and why the tutor must know which

The grammar route mostly uses standardised, format-driven tests. In practice this means a predictable set of topics, tightly timed multiple-choice or short-answer questions, and standardised marking. The upside for preparation is that the syllabus is knowable: a tutor who works this route regularly will drill the exact question types the test rewards, in the exact format your child will see on the day. Familiarity with the format is a real part of the score.

The independent route is more varied. Selective independent schools often set their own maths papers, and increasingly use a common pre-test at 10 or 11 as a first sift. These papers lean harder on multi-step problem solving and clear written working, and they are less predictable than a standardised grammar test. Preparing for them is less about drilling a fixed format and more about building genuine mathematical fluency and the confidence to attack an unfamiliar problem.

The practical point for choosing a tutor: ask directly which route they prepare for, and which local schools their past students have sat and entered. A tutor who cannot answer that specifically is guessing at your target, and you will find out on results day.

What the maths paper actually tests — beyond the classroom

Whichever route you take, 11+ maths sits on top of the Key Stage 2 national curriculum and then stretches past it. Your child's school covers the foundation; the exam demands more speed, more reasoning, and a few topics the classroom may not have reached yet.

Expect multi-step worded problems where the maths is buried inside the language and the first skill is working out what is being asked. Expect ratio and proportion, rate and speed, fractions and percentages under time pressure, and often a taste of early algebra. Almost all 11+ maths is non-calculator, so quick, accurate mental arithmetic is not a nicety — it is the difference between finishing the paper and running out of time. A child who is strong at school maths but slow, or who freezes on an unfamiliar problem, can still struggle here. That gap between "good at maths" and "ready for the 11+ maths paper" is exactly what a focused tutor closes.

One feature parents often do not know about: most 11+ tests use age-standardised scoring. A child's raw mark is adjusted for their age in months, so a summer-born child sitting the same paper as an autumn-born classmate is not penalised for being up to a year younger. It is a fair system, but it also means you cannot read a raw practice-paper score at face value — a tutor who understands standardisation will set realistic expectations rather than alarm you with a raw number.

How to judge a tutor's credibility — not just their claims

Here is the part almost every "how to find a tutor" article skips. Anyone can write a confident profile. The claim "experienced 11+ maths specialist, DBS checked, proven results" costs nothing to type, and on an ordinary directory you are simply trusting that it is true.

Tutorwise is built to remove that leap of faith. A tutor's credibility on Tutorwise is not a self-written bio — it is a computed credibility score built from real, checkable signals. A verified DBS certificate and confirmed identity, actual qualifications, the outcomes a tutor has delivered on the platform, and reviews from families who have worked with them all feed a single score that the tutor earns rather than writes. Because the score is assembled from evidence, it moves when the evidence does. A tutor cannot simply declare themselves trusted; they have to have been checked, and you can see the basis of it.

For an 11+ maths decision, that matters twice over. First, safety: an 11+ tutor works one-to-one with a young child, in your home or online, and a verified DBS and identity check is the floor, not a bonus. Second, effectiveness: reviews and delivered outcomes tell you whether this person has actually helped children like yours toward the schools on your list — not whether they are good at describing themselves. When you shortlist on Tutorwise, you are comparing earned, checkable scores side by side, which is a very different exercise from reading three equally glowing paragraphs and guessing.

Local, online, one-to-one or a small group

For South-East London families, both in-person and online tutoring work well, and the honest answer is that the right format depends on your child, not on a rule. In-person sessions in Greenwich, Blackheath, Lewisham or Dulwich suit younger or more easily distracted children who focus better with someone in the room. Online opens up a far wider pool of specialist 11+ maths tutors than your immediate postcode, which matters if you are targeting a specific school and want someone who knows that exact paper.

One-to-one gives your child the full attention and a plan built around their weak spots. A small group can work for a confident child who is motivated by a bit of pace and comparison, and it usually costs less per session. Neither is automatically better. Start from where your child concentrates and what you are preparing for, then choose the format that fits.

When to start

Most families begin structured 11+ maths preparation in Year 4 or Year 5, giving time to build fluency before the exam-technique phase in Year 6. That said, starting later is not a lost cause — a strong tutor will triage what matters, cut what does not, and focus a shorter run on the highest-value topics and the specific format your target schools use. The best time to start was earlier; the second-best time is now, with a clear target and a tutor whose credibility you can actually check.

Frequently asked questions

Is 11+ maths the same as the maths my child does at school? No. It builds on the Key Stage 2 curriculum but stretches past it, with more multi-step problem solving, tighter timing, non-calculator arithmetic, and some topics the classroom may not have reached. A child who is comfortable at school can still need targeted preparation for the exam's speed and style.

Do I need a tutor who specialises in a specific South-East London school? Ideally, yes — or at least one who knows your route. A Bexley or Kent grammar test and an independent school's own maths paper reward different preparation. Ask any prospective tutor which local schools their students have sat and entered.

How do I know a tutor is safe to work with my child? Look for a verified DBS certificate and confirmed identity, not just a claim. On Tutorwise these checks feed a tutor's computed credibility score, so you can see that the verification actually happened rather than take it on trust.

One-to-one or a small group for 11+ maths? One-to-one gives a plan built around your child's weak spots; a small group can suit a confident child and costs less per session. Choose by how your child concentrates and what you are preparing for.

When should we start preparing? Year 4 or Year 5 is common, which leaves room to build fluency before Year 6 exam technique. Starting later still works — a good tutor will focus a shorter run on the topics and format that matter most.

Finding your tutor

If you are preparing for the 11+ in South-East London, start by fixing your target schools, then shortlist maths tutors by the one thing you can actually verify: earned credibility. On Tutorwise you can compare 11+ maths tutors by a computed score built from verified checks, qualifications, outcomes and reviews — and start with the person whose record stands up, not the one with the best-written profile.
