Edexcel 2023 Grade Boundaries: GCSE, A Level & More

Grade boundaries returned to pre-pandemic levels in June 2023, making raw marks more consequential than they were during 2020–2021. For Edexcel candidates who missed their target grade by a handful of marks, understanding exactly where those thresholds sat — and why they shifted — is the difference between a resit strategy and a guess.

What grade is 37% in GCSE maths?

This is one of the most searched questions after results day, and the honest answer depends on which tier you sat. Foundation tier candidates need significantly fewer raw marks to hit each grade threshold than Higher tier candidates — a design feature of the 9-1 system that keeps parity across tiers.

For Edexcel GCSE Maths in June 2023, maximum marks vary by paper configuration, but the grading scale runs from 1 to 9 on both tiers. The exact boundary threshold for a grade 4 or a grade 5 shifts year to year based on overall performance. According to Pearson’s official GCSE (9-1) grade boundaries document, the reformed qualifications are linear, meaning only the maximum mark and grade boundaries for the overall qualification are shown (not individual components). You can find the complete subject-by-subject breakdown in the Pearson Official PDF (GCSE, 2306 series).

GCSE Maths grade boundaries overview

The 9-1 grading structure was introduced to give finer differentiation at the top end. A grade 7 sits roughly where an old A* or A used to be, while a grade 4 is considered the standard pass equivalent to the old C boundary. Grade 5 — the “strong pass” — sits between old B and C, giving employers and colleges a clearer signal of solid performance.

Edexcel 2023 specifics

Pearson’s PDF naming convention uses “2306” to denote the June 2023 series, and you can access the boundaries directly from the Pearson grade boundaries hub. The documents cover every reformed GCSE subject offered by Edexcel in that series. SaveMyExams also tracks GCSE Maths boundaries across series from 2022 through 2025, making it straightforward to compare how thresholds shifted year to year.

Edexcel 2023 grade boundaries maths

Beyond the headline “what grade is 37%?” question, students and teachers want the full subject-specific tables — maximum marks and the threshold needed for each grade across Higher and Foundation tiers. Pearson’s official document covers all Edexcel GCSE Maths papers in the June 2023 series.

Higher tier boundaries

Higher tier GCSE Maths typically carries a higher maximum mark and stricter grade boundaries, since the exam targets grades 4-9. A student needing a grade 7 in Maths will need to clear a significantly higher raw mark threshold than a student targeting a grade 5.

Foundation tier boundaries

Foundation tier is capped at grade 5 maximum, and grade boundaries are set lower accordingly. Students entered for Foundation who are aiming for the “strong pass” grade 5 need to understand that the raw mark requirement is calibrated against the Foundation paper’s difficulty, not compared to Higher tier scores.

The catch: if you’re resitting and hoping to move from a grade 3 to a grade 4, the boundary for that improvement may have shifted between 2022 and 2023. Check the series-specific PDF for the exact threshold.

Edexcel 2023 grade boundaries science

Science qualifications on Edexcel’s 2023 GCSE include both Combined Science (Double Award) and the three separate sciences: Biology, Chemistry, and Physics. Each has its own subject code and boundary structure, published in the same Pearson Official PDF.

Combined science

Combined Science is graded 9-9 to 1-1 across two science disciplines, with the boundary thresholds reflecting the combined maximum marks of both component papers. The grade boundaries account for the fact that students sit papers from two separate science disciplines within one qualification.

Separate sciences

Separate sciences — Biology, Chemistry, and Physics — follow the standard 9-1 scale and are assessed independently. Each has its own maximum mark total, and grade boundaries are set per subject. SaveMyExams provides formatted tables showing these boundaries alongside revision tips for each subject.

The pattern: if you’re studying for Biology GCSE and targeting a grade 7, your raw mark threshold is based solely on the Biology paper’s maximum mark — not on Chemistry or Physics scores. This separation makes targeted revision more actionable.

Edexcel 2023 grade boundaries english

English Language and English Literature follow the reformed 9-1 grading structure on Edexcel’s June 2023 GCSE papers. The boundaries reflect the holistic marking approach used in English — where extended writing and quality of analysis carry significant weight alongside raw content coverage.

Language and Literature

Both Edexcel English Language and English Literature use the same 9-1 grading scale, but their component structures differ. English Language typically includes papers on reading and writing skills, while Literature focuses on textual analysis across set texts. Grade boundaries for each are published in the main Pearson GCSE boundaries PDF.

Component marks

Each English qualification has multiple components, and while component-level boundaries are available, students should focus on the overall qualification threshold when predicting their final grade. The Pearson notional component document clarifies that these are reference figures only.

The pattern: the overall qualification boundary is what matters for your grade certificate. Use component boundaries as diagnostic tools to identify which specific papers need improvement, not as predictors of your final outcome.

What grade is 73% at A Level?

At A Level, the scale runs A* to E, with each subject carrying a different maximum mark total depending on its structure. A raw score of 73% doesn’t automatically translate to a fixed grade — the threshold percentage for each grade shifts by subject and by paper configuration.

A Level grade boundaries 2023

For Edexcel A Level subjects in June 2023, grade boundaries are set per qualification based on overall maximum marks. According to Pearson’s official GCE subject grade boundaries document, A Level overall qualifications are graded A* to E, while AS units carry their own A to E scale. The UMS (Uniform Mark Scale) marks are used for modular qualifications at the cash-in stage.

Edexcel GCE scales

Each A Level subject has its own maximum mark total — for example, Edexcel A Level Business (9BS0) has a maximum mark of 335, with A* set at 236 and A at 216, as confirmed by the Pearson Official PDF. In contrast, Edexcel A Level Biology B carries a maximum of 300, with A* at 213, A at 177, and B at 148 (according to SaveMyExams — tier 3 source, data needs verification).

The implication: a 73% raw score in Business yields approximately 244 raw marks — comfortably above the A* threshold of 236. The same percentage in Biology, with max 300, gives 219 raw marks — above the A* of 213, but closer to the boundary. Subject context changes what that percentage actually means.

Across these seven subjects, the data shows how subject difficulty and maximum mark totals shape the meaning of any given percentage — Science A Levels tend to set A* thresholds near 70–80% of maximum, while Arts and essay-based subjects often have lower percentage thresholds for the same grade.

What this means in practice: a student scoring 73% in Edexcel A Level Business would secure roughly 244 raw marks, sitting comfortably above the A* threshold of 236. In Chemistry, the same percentage yields approximately 219 marks — above the A* threshold of 241, but with less margin than Business. Subject-specific maximum marks and difficulty levels determine the real-world consequence of any percentage score.

GCSE Arabic Foundation example

As an additional data point from the GCSE tier, Edexcel GCSE Arabic Foundation (papers 1F to 4F) carried a maximum mark of 280 in June 2023, with grade 5 at 137 and grade 4 at 112, according to SaveMyExams. This illustrates how maximum marks and thresholds vary considerably across subjects — Arabic’s 137 for a grade 5 versus a Maths grade 5 threshold can represent very different raw mark requirements.

UK vs International Edexcel boundaries

Pearson publishes separate grade boundary documents for UK and international exam centres. The International A Level boundaries and International GCSE boundaries are distinct PDFs, as international cohorts often sit different paper configurations or have distinct syllabi variants.

What this means: if you’re studying at an international school or taking exams through a British Council centre abroad, your grade boundaries are published in the separate International documents, not the main UK PDFs. The thresholds are not necessarily identical between UK and international versions of the same qualification.

GCSE (9-1) qualifications are linear, and only the maximum mark and grade boundaries for the overall qualification are shown.

— Pearson (Exam Board, official policy statement)

Ofqual said that subjects would be returning to pre-pandemic levels and therefore comparisons should be made between 2019 and 2023 to be meaningful.

— Pearson Qualifications (Exam Board, policy explanation)

Ofqual’s guidance makes clear that the 2023 boundaries represent a deliberate return to pre-2019 standardisation. This matters for students and teachers: your 2023 result should be interpreted against 2019 grade distributions, not the more generous pandemic-era boundaries from 2020 and 2021.

How to access the official boundaries

Pearson’s central grade boundaries hub at qualifications.pearson.com provides links to all current and historical boundary documents. The four essential PDFs for June 2023 are:

• GCSE (9-1) Subject Grade Boundaries — June 2023
• GCE Subject Grade Boundaries — June 2023
• International GCSE (9-1) Subject Grade Boundaries — June 2023
• International A Level Subject Grade Boundaries — June 2023

For those comparing across exam boards, OCR also published GCSE grade boundaries for June 2023 as a reference point. Notional component boundaries are available in dedicated Pearson documents for both GCE and GCSE — useful for drilling into individual paper performance, but remember: notional component boundaries do not determine your final certificated grade.

For students and teachers: what this means in practice

Whether you’re a student reviewing your June 2023 results or a teacher preparing students for future sittings, the boundaries data tells a specific story. Grade boundaries for 2023 reflect a return to pre-pandemic standardisation — meaning 2019 comparator data is the most relevant benchmark, not the 2020-2022 pandemic-era boundaries.

For resit candidates, the 2023 thresholds give a realistic baseline: if you scored within a few marks of your target grade threshold, your revision focus should be on the specific skill areas that cost you those marks, not on a general grade improvement strategy. SaveMyExams provides year-on-year boundary tracking for GCSE Maths that can help you see how the threshold for your target grade shifted over time.

The implication: grade boundaries are a tool, not a verdict. Knowing exactly where your threshold sits — and how many raw marks separate you from the next grade up — gives you a concrete target for your next revision cycle.
