How GCSE Grades Work: The 9–1 System Explained
If you're opening results this week, you need to know what your grades actually mean. Here's the 9–1 scale explained — what counts as a pass, how boundaries work, and what happens next.
The 9–1 scale at a glance
GCSEs are graded 9 to 1, where 9 is the highest and1 is the lowest. The scale replaced the old A*–G system and maps roughly like this:
| New grade | Old scale equivalent | What it means |
|---|---|---|
| 9 | Above A* | Top few percent of candidates |
| 8 | A* | Excellent |
| 7 | A | Excellent — often required for competitive courses |
| 6 | B | Good |
| 5 | High C / low B | Strong pass |
| 4 | C | Standard pass — the benchmark |
| 3 | D / E | Below pass level |
| 2 | F | Low |
| 1 | G | Lowest grade |
What counts as a pass?
Grade 4 is a standard pass and grade 5 is a strong pass. These are the numbers that matter most: many sixth forms, colleges, and apprenticeship programmes use 4 as their baseline and 5 as their preferred threshold. A grade 3 or below in English or Maths means you'll usually need to keep studying those subjects.
How grade boundaries work
There's no fixed percentage for each grade. After every exam series, exam boards set boundaries based on the difficulty of the papers and how students actually performed. That's why a grade 7 might be 65% one year and 70% the next, and why the boundary for a grade 4 in Maths differs from English. Official boundaries are published by each board (AQA, Edexcel, OCR, WJEC) on results day.

What grades do you need for sixth form?
- Baseline: usually at least four or five GCSEs at grade 4+, including English and Maths.
- A-level subjects: schools typically want a 6 or 7 in each subject you plan to take at A-level.
- Competitive courses: medicine, law, and top sixth forms often look at 7s and 8s, sometimes a minimum average GCSE score.
If your results come in below expectations, don't panic — options include resits (November for English and Maths), appeals, or alternative routes like BTECs and apprenticeships.

Frequently asked questions
What is a pass in GCSE?+
Grade 4 is a standard pass and grade 5 is a strong pass in the 9–1 system. Grade 4 is roughly equivalent to the old C. Most sixth forms and colleges ask for at least a 4 in English and Maths, and many competitive courses want a 5 or higher.
How do GCSE grades work?+
GCSEs are graded from 9 (highest) to 1 (lowest). Grade 9 is above the old A*, grade 4 is a standard pass, and grade 1 is the lowest. The scale replaced the A*–G system between 2017 and 2020.
What is the difference between grade 4 and grade 5?+
Both sit in the old C range, but grade 5 is a 'strong pass' and grade 4 is a 'standard pass'. Grade 5 is roughly the top half of the old C (low B territory), while grade 4 covers the rest of the old C. Employers and sixth forms often prefer 5s.
What GCSE grades do I need for sixth form or college?+
Most sixth forms require at least four to five GCSEs at grade 4 or above, including English and Maths. Competitive courses typically ask for 6s and 7s in relevant subjects, and some schools have a minimum average GCSE score for entry.
What happens if I fail GCSE English or Maths?+
If you get below grade 4 in English or Maths, you normally must continue studying them (often as a resit) until you pass or turn 18. Colleges and apprenticeships treat these two subjects as essential for progression.
Are GCSE grade boundaries the same every year?+
No. Boundaries are set after each exam series based on paper difficulty and student performance, then published by each exam board (AQA, Edexcel, OCR, WJEC). They vary by subject and can shift by a few percentage points between years.
Is a grade 9 better than an A*?+
Yes. Grade 9 is a new top grade above the old A*, awarded to roughly the top few percent of students. It was introduced to better differentiate the highest performers under the old A* system.
What percentage is a grade 7 at GCSE?+
Grade boundaries vary by exam board and subject, but a grade 7 is typically around 65–70% of the total marks. Use our GCSE grade calculator with your own marks to get an estimate, and check the official boundaries from your exam board.
