One-to-one preparation for the maths in the 11+, from £11 a class with the same teacher every week. We teach the maths paper only — not verbal reasoning, non-verbal reasoning or English — and we would rather say so before you book.
What is ClassArc?
ClassArc is live one-to-one online maths tutoring for school-age children. One teacher and one child, for 55 minutes. The same teacher every week. Classes run inside our own classroom software, not a video call: a shared worksheet you both write on, a shared whiteboard, and answers that sync live.
What we teach
Most 11+ tests have several parts: maths, English, and in many areas verbal and non-verbal reasoning. ClassArc teaches the maths. If your child's test includes reasoning or English papers, those need preparing elsewhere, and it is better to know that now than in July.
Keeping to maths is deliberate. Our teachers are maths teachers, and a lesson split four ways tends to leave every paper slightly under-prepared.
minutes of maths, one to one, with the same teacher each week. The first class is free and needs no card.
The tests
The 11+ is not one exam. It is a family of entrance tests for Year 7 entry, and the maths inside each one looks different depending on who wrote it.
GL Assessment writes the test for many grammar school areas. Its papers are usually multiple choice, answered on a separate sheet, and each area decides which subjects to include.
Cambridge Select Insight is the name, since April 2025, of the computer-based test once called CEM Select, used mainly by independent schools. A guide that still talks about a CEM grammar test may simply be out of date.
The ISEB Common Pre-Test is an online, adaptive multiple-choice test used by many independent schools. Because it adapts, a run of hard questions usually means a child is doing well, not badly.
School-set papers vary the most. Sutton's Selective Eligibility Test, for instance, covers maths and English with no reasoning papers, and children who pass sit a written second stage in October.
Tell us the schools first. The format decides half of what the preparation looks like.
What we ask an 11+ parentWhere marks go
Most of the maths draws on Key Stage 2, but a child gets far less time per question than on a school test. Quick, secure fractions and times tables are what buy that time back.
One question can ask for a percentage, then a ratio, then a change of units. Children who manage each step alone often lose the thread between them.
Missing-number puzzles, algebra described in words, a sequence with a twist. The maths is familiar; the way it is asked is not, and that unsettles a ten-year-old.
How we prepare
The order matters. Timed papers on shaky foundations mostly teach a child to guess faster.
Nearly every 11+ problem we are shown turns out to be a fractions or place-value problem wearing a disguise.
What the first class usually findsThe free class starts a little above your child's current work and steps back until the ground is firm, so preparation begins from what is actually secure.
Area of compound shapes, multi-step word problems, simple algebra and number sequences: the topics these papers reach for before school has finished teaching them.
Multiple choice means learning to rule out wrong options and move on. Written papers mean setting out working clearly enough for a marker to follow it.
From the spring or summer of Year 5, practice moves to timed sections and then full papers in the format your child will actually meet.
Coverage
Built on the Key Stage 2 curriculum, usually asked faster and in less familiar ways than at school.
Why families choose us
We prepare the maths paper. We will not pretend to cover reasoning or English, and we tell you if your child's test weights those heavily.
One person who learns how your child thinks under time pressure, rather than a new tutor at every session.
Teacher and child write on the same live worksheet, so a slip in step two of a four-step problem is caught where it happens.
Set to match the lesson, submitted inside ClassArc as a photo or typed answer, and reviewed by the teacher before the next class.
Entry depends on each school's scores and how many children apply that year. Anyone promising a pass is selling a certainty they do not have.
Classes come in blocks that never renew by themselves, and unused classes are refunded if you stop.
Prices in pounds. Every class is 55 minutes, one-to-one, with the same teacher. First class free, no card required.

ClassArc is a one-on-one online tutoring service. We provide live, scheduled classes between a teacher and a student, along with homework, feedback, and study support.
Each class is 55 minutes. You can reschedule or cancel a class up to 5 minutes before it starts. If you miss a class without notice, we usually credit it back to your balance and reschedule based on what works for the teacher and student.
The first demo class is free, no card required. After that, plans are billed in advance for the number of classes you choose (8, 24, or ~48). We'll send you a payment link directly once you've picked a plan.
If you want to stop classes at any point, we refund whatever class balance is left on your plan. No questions asked, no friction. Refunds are processed within 7 business days.
We expect students and parents to treat teachers with respect, and teachers to do the same. We reserve the right to end the relationship if classes become unsafe, abusive, or disruptive, with a full refund of any unused balance.
If we update these terms, we'll email you before the changes take effect, so you have time to review them.
For anything, email hello@theclassarc.com.
