Ten DfE rows, eight sixth forms and one cohort of 43 that appears three times: Wimbledon's 2024/25 A-level Biology figures, read with each sixth form's board and GCSE grade.
RR6 is the joint sixth form of Rutlish School and Ricards Lodge High School in Wimbledon, and the 2024/25 A-level Biology file from the Department for Education (DfE) reports its 43 matched entries three times: as RR6, and again as Rutlish's 17 plus Ricards Lodge's 26. The ten Wimbledon rows in that file describe eight sixth forms, which Compare school and college performance credits with 175 A-level Biology entries.
Our expert A-level Biology tutors help students across Wimbledon build a programme around their own sixth form's exam board and the papers its department sets, whether that is AQA, OCR or Pearson Edexcel.
How can one sixth form's 43 Biology entries appear in three rows?
DfE publishes A-level value added school by school. In its Merton file RR6 has a row under its own URN, 136509, and Rutlish School and Ricards Lodge High School each have a row under theirs. The Get Information about Schools register records RR6 as a sixth form centre for ages 16 to 19 at Ricards Lodge's address in Lake Road, linked to both schools as a "Sixth Form Centre School".
DfE counts an entry towards value added only where the student has results from the end of key stage 4 to be compared against, so its count can sit below the count of every entry that Compare publishes. This page calls the value-added count "matched entries" and the other "Compare entries".

Sorted by matched entries, not by score; the last two rows are working, not DfE rows. Every value-added figure in this table is DfE's progress measure for 2024/25 entrants, not a measure of teaching quality. Sources: DfE subject value-added dataset, 2024/25, A level cohort, Biology; Compare school and college performance, subjects entered at 16 to 18.
The entry counts are whole numbers and they add up. Ricards Lodge's 26 and Rutlish's 17 make RR6's 43 matched entries, and the Compare entries partition the same way: 28 for Ricards Lodge and 17 for Rutlish make RR6's 45. The three rows are therefore not three cohorts. They are one cohort of 43 matched entries, reported under three names.
The scores agree with the addition. The last row of the table shows the working: weighting the two partner rows' scores by their matched entries gives -0.0328, and RR6's own row, -0.03 with a 95% interval of -0.35 to 0.29 from 43 matched entries, is that figure rounded. All of these figures are DfE's progress measure for 2024/25 entrants, not a measure of teaching quality. Treat the agreement as corroboration. The whole-number entry counts are what show the rows overlap, and one matching weighted average does not by itself describe how DfE combines scores.
For a family, that changes what to read. The row that describes the sixth form is RR6's own, and its interval spans zero. The other two rows are parts of that cohort, so summing the matched entries down the column would count the same 43 entries twice (43 + 26 + 17 = 86), and reading the two partner rows as findings of their own would count one cohort as three. Two of the three intervals clear zero, in opposite directions; the third, the sixth form's own, does not.
Our expert A-level Biology tutors help students across Wimbledon whichever sixth form's row they sit in, building each programme around that sixth form's own board and papers rather than around a score in a table.
How many A-level Biology entries did Wimbledon's sixth forms record in 2024/25?
Compare lists 175 GCE A-level Biology entries across the eight sixth forms in 2024/25. DfE counts entries rather than people, so the figure is a count of entries and not a head count.

Adding all ten Wimbledon rows in DfE's Merton file gives 220, not 175, because RR6's 45 is counted a second time as Rutlish's 17 plus Ricards Lodge's 28.
Which schools count as Wimbledon is a rule, and the rule here is the postcode. DfE publishes results by local authority, and Wimbledon sits within the London Borough of Merton, local authority 315, so Merton's file has to be cut down to the part that is Wimbledon. The starting point is every open establishment on the Get Information about Schools register with an SW19 or SW20 postcode and a top age of 16 or more. The register's extract dated 29 September 2026 lists 14.
Four of the 14 are not mainstream sixth forms: Linden Lodge School is a special school, the Norwegian School in London stops at 16, TCES National Online School is an online provider and Wimbledon School of Art is an art and design college. None of the four has a row in DfE's Merton Biology file. The other ten are the ten Wimbledon rows in that file. Ursuline High School Wimbledon appears there under URN 102683, the record that closed on 31 January 2025 at the school's conversion to an academy; the school is open under URN 151350 from 1 February 2025.
The register's constituency field is not a safe substitute for the postcode. It also files Coombe Boys' School, Richard Challoner School and The Holy Cross School under the Wimbledon parliamentary constituency. All three are registered in Kingston upon Thames with KT3 postcodes in New Malden, and none is in the Merton file.
The Merton file has twelve Biology rows, so two fall outside the rule. Harris Academy Merton (Wide Way) and St Mark's Church of England Academy (Acacia Road) have CR4 postcodes in Mitcham, in the Mitcham and Morden constituency. Their rows are shown so that the rule can be checked against them.

Sorted by matched entries, not by score. Each figure is DfE's progress measure for 2024/25 entrants, not a measure of teaching quality. Neither interval clears zero, so the count of Merton rows that do is three with or without these two.
What do the published Biology figures say once RR6 is counted once?
Seven of the eight sixth forms have a published Biology figure; Hall School Wimbledon's is suppressed. Each figure below is DfE's progress measure for 2024/25 entrants, not a measure of teaching quality. It compares a sixth form's A-level results with those of students nationally who had similar GCSE results, so the grade a sixth form asks for at entry is already allowed for in its score.

Rutlish School's and Ricards Lodge High School's rows are the RR6 rows in the first table and are not repeated. "c" is DfE's symbol for a suppressed figure.

One of the seven sixth forms has an interval wholly above zero. Wimbledon High School GDST's score is 0.71, with a 95% interval of 0.26 to 1.15 from 22 matched entries: DfE's progress measure for 2024/25 entrants, not a measure of teaching quality. The other six span zero, so zero remains a possible true score for each of those cohorts.
An interval's width follows cohort size: it is 0.64 across the 43 matched entries of the largest cohort in the table and 1.26 across the 11 of the smallest.
Counted by row, three intervals clear zero. Two of the three are the RR6 partner rows, which the first table showed to be parts of one cohort of 43 matched entries whose own interval spans zero. Counted by sixth form, one does. That is the difference between reading the file as ten independent schools and reading it as eight sixth forms, and it is the reason to start from the addition rather than from the column of scores.
Our expert A-level Biology tutors help students across Wimbledon work from the sixth form they are actually in, not from a score in a table: the board it names, the papers its department sets and the GCSE grade it asked for at entry.
My son was low in confidence after COVID and the gaps in learning were building up. Using this service helped plug those gaps, rebuild confidence, and improve his ability to learn properly again.

Amazing tutors!
We arranged maths and English tuition ahead of GCSEs and both tutors were brilliant. My daughter's grades improved, and by results day she achieved two grades higher than in her mock exams.

Great Teaching and Focused Learning
I attended an English bootcamp with Leading Tuition and the experience was excellent. The teacher gave focused attention to the small group while keeping the lessons interactive and engaging.
Do Ursuline and Wimbledon College run one Biology course or two?
The two schools publish one document, the Ursuline High School and Wimbledon College Course Guide for September 2026, subtitled "including subjects taught at Wimbledon College". It lists A-level Biology twice: "Taught at Ursuline Sixth Form", with the board given as OCR, and "Taught at Wimbledon College", with the board given as Pearson Edexcel.
The entry documents expect students to move between the two sites. Ursuline's entry criteria for 2027 say that a student who enrols at Ursuline and takes an A level at Wimbledon College must also meet Wimbledon College's minimum for the subject. Wimbledon College's 2026 entry requirements say that a course at Ursuline needs the higher of the two schools' criteria.
DfE's technical guidance adds one rule: all of a student's results are attributed to a single school or college, including any results studied elsewhere. The Merton file has a row for each school and none for the two together. Read together, the guide and the rule mean that a row's school name does not, on its own, say which of the two Biology courses a student in that row sat, or on which board. The practical step for a family is to ask the department which course and which board a given student will take.
Wimbledon College's row belongs to URN 102681, which the register lists as open but proposed to close on 30 November 2026 for academy conversion.
Which Wimbledon sixth forms are reporting their first A-level cohort?
Two of the eight publish dates that make 2024/25 their first A-level cohort. Harris Academy Wimbledon's sixth form, HAWI6, has a results page headed "Our First Cohort Make History", and a job listing dated 21 April 2026 says the academy celebrated its first A Level results in 2025. The 22 Biology entries Compare lists for 2024/25 come from that first cohort.
Hall School Wimbledon says on its sixth-form page that it launched its sixth form in September 2023, so its 2024/25 cohort is also its first. Compare lists one A-level Biology entry for Hall that year, and DfE's value-added file shows "c" in all four of its Biology columns.
A first cohort is one year of evidence about one group of students. It is a reason to ask a school for its current results and its teaching plan, and not a reason to read anything into a single row.
Which exam board and GCSE grade does each Wimbledon sixth form ask for in Biology?
The table gives each sixth form's own words for its board and its Biology entry requirement. How the boards differ in content and paper structure is set out in our A-level Biology guide and on the AQA, OCR and Edexcel pages, and is not repeated here.

"Grade 6 or higher in GCSE Biology and a Grade 6 or higher in either GCSE Chemistry or Physics OR GCSE Grade 66 in Combined Science."
Not found. Its subject list places Biology under both A level and the International Baccalaureate Diploma (Group 4), and Compare lists 14 Higher Level and 12 Standard Level IB entries under Biology beside its 29 A-level entries.
"Triple Science, incl. 7 in GCSE Biology and minimum 6 in Chemistry and Physics" or "Double Science: 7, 7", on top of "5 or above in English Language and Maths and a GPA of 6.5 or above"
Sorted by Compare entries, as in the second table. Entry years differ between documents and every school issues a new one each year, so check the current version before relying on a grade.
Six of the eight name a board in their own documents: three name AQA, two name OCR and one names Pearson Edexcel. Six publish a Biology grade: four ask for a 6, Harris Academy Wimbledon asks for a 7 and Wimbledon High School GDST asks for grades 8 or 9. For King's College School and Hall School Wimbledon we found no board and no Biology grade on the public pages we read. That describes our search and not the schools, and a call to either school settles it.
Our expert A-level Biology tutors help students across Wimbledon reach the GCSE grades a sixth form asks for in Year 11, and then work through the board's papers in Years 12 and 13, whichever of the sixth forms above they attend.
How does Leading Tuition work with Wimbledon A-level Biology students?
Everything above describes a row or a document. Tutoring has to describe one student. Our expert A-level Biology tutors help students across Wimbledon start from the three things this page has pinned down: the sixth form the student is actually in, the board that sixth form names, and the GCSE grade it asked for at entry. For a Year 11 student working towards Harris Academy Wimbledon's grade 7 in Biology or RR6's grade 6, the work is on the GCSE Biology, Chemistry and Physics grades the sixth form will look at. For a Year 12 or Year 13 student it is on the board's papers, the practical endorsement and the department's own class tests and mock papers.
How many students sit A-level Biology at Wimbledon's sixth forms?
Compare school and college performance lists 175 A-level Biology entries across Wimbledon's eight sixth forms for 2024/25: RR6 45, King's College School 29, Ursuline High School Wimbledon 23, Harris Academy Wimbledon 22, Wimbledon College 22, Wimbledon High School GDST 22, Raynes Park High School 11 and Hall School Wimbledon 1. DfE counts entries, not people. Adding the rows for Rutlish School (17) and Ricards Lodge High School (28) as well would give 220, because their entries are already inside RR6's 45.
Can I add up the RR6, Rutlish and Ricards Lodge Biology rows?
No. RR6's 43 matched entries are Ricards Lodge's 26 plus Rutlish's 17, and Compare's counts partition the same way: 28 plus 17 make RR6's 45. Adding all three matched-entry figures gives 86, which counts the same 43 entries twice. The value-added file leaves two of Ricards Lodge's 28 Compare entries out, which is why its row shows 26. The row that describes the sixth form is RR6's own, and the other two are parts of its cohort.
Which exam boards do Wimbledon sixth forms use for A-level Biology?
Six of the eight name a board in their own documents. Harris Academy Wimbledon, Raynes Park High School and Wimbledon High School GDST name AQA, RR6 and Ursuline High School Wimbledon name OCR, and Wimbledon College names Pearson Edexcel. Ursuline and Wimbledon College publish one joint course guide that lists Biology on OCR at Ursuline and on Pearson Edexcel at Wimbledon College. We found no board for King's College School or Hall School Wimbledon.
What GCSE grades do Wimbledon sixth forms ask for in A-level Biology?
Four ask for a grade 6 in Biology: RR6, Ursuline High School Wimbledon, Wimbledon College and Raynes Park High School. RR6 also accepts grade 66 in Combined Science. Harris Academy Wimbledon asks for a 7 in triple-science Biology with a 6 in Chemistry and Physics, or 7-7 in double science, and Wimbledon High School GDST requires grades 8 or 9 in the subjects to be studied. Each school issues its requirements afresh every year.
Does a Wimbledon sixth form's Biology score measure the quality of its teaching?
No. The figure is DfE's progress measure for 2024/25 entrants: it compares students' A-level results with those of students nationally who had similar GCSE results. It is not a measure of teaching quality, and its 95% interval matters as much as the score. Of the seven Wimbledon sixth forms with a published figure, six have intervals that span zero. An interval is 0.64 wide across the largest cohort of 43 matched entries and 1.26 wide across the smallest of 11.
Does King's College School's Biology score include its International Baccalaureate students?
No. DfE's row covers King's A-level cohort, which Compare puts at 29 entries. King's own subject list places Biology under both A level and the International Baccalaureate Diploma, and Compare lists 14 Higher Level and 12 Standard Level IB entries under the same subject name, so the A-level row does not describe those students. The Merton Biology file carries no IB value-added row for King's, so the IB route has no DfE score on this page.
Why does Hall School Wimbledon have no Biology score?
DfE's value-added file shows the symbol c, which it uses for a suppressed figure, in all four of Hall School Wimbledon's Biology columns. Compare lists one A-level Biology entry for Hall in 2024/25, and 16 A-level entries across all of its subjects. The school says it launched its sixth form in September 2023, so 2024/25 is its first A-level cohort.
