11 Plus Tutor in Sidcup: Expert Preparation for Chislehurst and Sidcup Grammar and Beths Grammar

If you live in Sidcup you can walk to Chislehurst and Sidcup Grammar School. What you cannot do is walk your child into a place there. With around seven hundred children competing for fewer than two hundred Year 7 places, geographical proximity gives no advantage whatsoever in the exam. The children who pass have prepared across every subject the paper tests: English, mathematics, verbal reasoning, and non-verbal reasoning. Those who have not prepared to that standard, however naturally able, typically do not score as well as they could.

At Geek School Tutoring, we have been preparing children for grammar school entrance exams in Bromley and Bexley since 2013. More than 1,000 families have trusted us. Our 100% pass rate for Kent and Medway grammar schools reflects a programme built specifically around the exams your child will sit, not a generic syllabus. Our Beckenham centre on Beckenham Road, BR3 is around twenty minutes from central Sidcup by car.

Schools Sidcup Families Target: What Each Exam Involves

Chislehurst and Sidcup Grammar School

Chislehurst and Sidcup Grammar uses GL Assessment multiple-choice papers covering English, mathematics, verbal reasoning, and non-verbal reasoning. The qualifying threshold shifts each year depending on the applicant pool. The VR and NVR papers are where many children lose ground, because these question types are not taught in the primary school curriculum and require specific, timed practice to score well. Children who score in the top band have almost always had systematic preparation across all four subjects from Year 4 or earlier.

Beths Grammar School

Beths Grammar in Bexley uses the same GL Assessment format as Chislehurst Grammar. English, mathematics, verbal reasoning, and non-verbal reasoning are all tested in multiple-choice papers. Places are allocated first by qualifying score, then by distance from the school. Sidcup’s DA14 and DA15 postcodes are within the typical distance for a qualifying child. Because the two schools use the same exam format, children preparing for one are effectively preparing for both simultaneously.

Dartford Grammar Schools

Dartford Grammar School for Boys and Dartford Grammar School for Girls use the Kent Test, which covers reasoning and literacy with verbal and non-verbal reasoning components. Children in Sidcup can apply to Dartford Grammar as they fall within the Kent priority area. The Kent Test format differs from GL Assessment, and we make sure children are familiar with both formats if Dartford is on their list alongside Chislehurst or Beths.

Year 3: Getting Ahead of the Competition

We take children from Year 3, which is earlier than most tutors. For Sidcup families targeting Chislehurst and Sidcup Grammar or Beths Grammar, starting in Year 3 gives us the most time to build the VR and NVR fluency these schools’ papers require. These are not skills that can be acquired quickly; they develop through regular, repeated exposure to different question types over an extended period.

In Year 3, sessions focus on building strong foundations in reading, writing, and number work, with a gentle introduction to reasoning question types in a format that feels more like puzzle-solving than exam preparation. Children who start at this stage arrive at Year 6 in a far calmer and more confident state than those who begin in Year 5.

Year 4 and Year 5: Building on the Foundation

Year 4 covers the full range of GL Assessment subjects in structured weekly sessions. Timed exercises are built in from early on, so working accurately under time pressure becomes a habit rather than a source of anxiety. In Year 5 we introduce full mock papers under exam conditions for the specific schools on your child’s list, followed by individual written feedback. We adjust the programme after each mock based on where each child’s scores show room for improvement.

Frequently Asked Questions

When should my child start 11 plus preparation if we live in Sidcup?

For Chislehurst Grammar and Beths Grammar, we recommend starting in Year 3 or Year 4. Both schools are heavily oversubscribed and the top-scoring children have almost always had structured preparation across all four GL Assessment subjects. Starting in Year 3 gives us the most time to build VR and NVR fluency, which is where the marks are often won or lost.

Do you take children from Year 3?

Yes. We take children from Year 3 onwards. Year 3 is a relaxed, exploratory stage focused on reading, vocabulary, number confidence, and a gentle introduction to reasoning question types. It is not pressured preparation at this stage. The benefits show up clearly in Year 5 and Year 6 results.

What is the GL Assessment and which schools use it?

GL Assessment is a test provider whose papers are used by many grammar schools including Chislehurst and Sidcup Grammar, Beths Grammar, Bexley Grammar, and numerous others across London and Kent. The papers typically cover English, mathematics, verbal reasoning, and non-verbal reasoning in multiple-choice format. GL Assessment papers have a consistent style, and children who have practised them systematically perform significantly better than those encountering them for the first time.

How does the Kent Test differ from the GL Assessment used by Chislehurst Grammar?

The Kent Test uses its own format with verbal reasoning, numerical reasoning, and spatial reasoning components, as well as a writing task in some stages. It is the test used for all Kent grammar schools including Dartford Grammar. It differs in format from the GL Assessment used by Chislehurst and Beths. If Dartford Grammar is on your child’s list alongside Chislehurst or Beths, we prepare them for both formats simultaneously.

Can my child sit both the Bexley tests and the Kent Test?

Yes. Children in Sidcup are eligible to sit both. Beths and Chislehurst Grammar use GL Assessment and are Bexley schools. Dartford Grammar uses the Kent Test. The tests take place at different times in September and early October of Year 6. We prepare children for all the relevant formats as part of the same programme.
