Grade Boundaries and Targeting
Understanding how Edexcel sets grade boundaries — and using that knowledge strategically — helps you focus your efforts where they will have the most impact on your final grade.
How Grade Boundaries Are Set
Grade boundaries are set after the exams, not before. Here is how the process works:
- All students sit the exam.
- Senior examiners review the papers and a sample of student scripts.
- They compare the difficulty of this year's papers with previous years.
- They set boundaries that maintain consistent standards year on year.
- Boundaries are published on results day.
What This Means
- If the papers are harder than usual, boundaries go down.
- If the papers are easier than usual, boundaries go up.
- You do not need a fixed percentage to get a grade — it varies.
- You cannot predict exact boundaries before the exam, but historical data gives a good range.
Typical Boundary Ranges
Based on recent Edexcel 1MA1 exam series, here are approximate boundary ranges. These are illustrative only — actual boundaries change every year.
Higher Tier (out of 240)
| Grade | Approximate Mark Range | Approximate Percentage |
|---|
| 9 | 180–205 | 75–85% |
| 8 | 155–180 | 65–75% |
| 7 | 125–155 | 52–65% |
| 6 | 95–125 | 40–52% |
| 5 | 70–95 | 29–40% |
| 4 | 50–70 | 21–29% |
Foundation Tier (out of 240)
| Grade | Approximate Mark Range | Approximate Percentage |
|---|
| 5 | 145–175 | 60–73% |
| 4 | 110–145 | 46–60% |
| 3 | 75–110 | 31–46% |
| 2 | 45–75 | 19–31% |
| 1 | 20–45 | 8–19% |
Key insight: On Higher, you can achieve a grade 7 with roughly half the marks. On Foundation, a grade 4 requires about half the marks. You do NOT need to answer everything correctly.
Strategic Question Selection by Tier
Foundation Strategy
On Foundation, the papers are designed so that grades 1–5 are accessible. The questions are:
- Questions 1–10: Typically grade 1–2 standard. Secure these marks.
- Questions 11–18: Typically grade 2–3 standard. These are your bread and butter.
- Questions 19–24: Typically grade 3–4 standard. Push for these.
- Questions 25–28: Typically grade 4–5 standard. Stretch questions.
If you are targeting grade 3: Focus on getting questions 1–18 right. That is likely 40–50 marks per paper, which should be enough.
If you are targeting grade 5: You need to answer most of the paper correctly, including the harder questions at the end.
Higher Strategy
On Higher, the papers are designed so that grades 4–9 are accessible. The questions are:
- Questions 1–8: Typically grade 4–5 standard. Secure these.
- Questions 9–15: Typically grade 5–6 standard. Solid marks here push you up.
- Questions 16–21: Typically grade 6–7 standard. This is where grade 7 is won.
- Questions 22–25: Typically grade 7–9 standard. The hardest questions.
If you are targeting grade 5: Focus on the first half of each paper. Secure 35–40 marks per paper.
If you are targeting grade 7: You need to answer correctly through about question 18–20. That means accessing the grade 6–7 questions confidently.
If you are targeting grade 9: You need high accuracy throughout AND success on the final questions. Aim for 60+ marks per paper.
When to Move On from a Hard Question
The 2-Minute Rule
If you have spent 2 minutes on a question and have not made meaningful progress:
- Re-read the question one more time.
- If you still cannot see a way in, circle the question number and move on.
- Come back to it after finishing the rest of the paper.
Why This Works
- The next question might be easier and worth the same marks.
- Time spent stuck earns 0 marks, but time spent on an accessible question earns marks.
- Coming back to a hard question with fresh eyes often helps.
- Your subconscious continues working on the problem while you do other questions.
Exception
If you are close to finishing a question (you have started the method and just need to complete it), push through rather than abandoning it — the remaining marks are likely easier than starting a new question.
Maximising Marks on Foundation
Priority 1: Secure the Basics (grades 1–3)
These topics appear in the first half of Foundation papers:
- Place value, ordering numbers, basic operations.
- Fractions, decimals and percentages of amounts.
- Simple ratio sharing.
- Basic angle facts (straight line, triangle).
- Perimeter and area of rectangles and triangles.
- Reading charts and tables.
- Mean, median, mode, range.
- Simple probability.
- Plotting coordinates.
- Simple equations.
Priority 2: Extend to Grade 4–5
These topics appear in the second half:
- Compound measures (speed, density).
- Percentage increase/decrease.
- Expanding and factorising single brackets.
- Solving linear equations with brackets.
- Interior and exterior angles of polygons.
- Circle area and circumference.
- Pythagoras' theorem.
- Scatter graphs and correlation.
- Frequency tables and averages.
- Basic probability trees.
Maximising Marks on Higher
Priority 1: Secure Grades 4–5
Same topics as Foundation — make sure you can do these quickly and accurately. These are the "free marks" at the start of Higher papers.
Priority 2: Grades 6–7 Topics
- Quadratic equations (factorising, formula, completing the square).
- Simultaneous equations.
- Trigonometry (SOH CAH TOA).
- Circle theorems.
- Bounds.
- Compound interest and depreciation.
- Direct and inverse proportion.
- Cumulative frequency and box plots.
- Algebraic fractions (simple).
Priority 3: Grades 8–9 Topics
- Sine and cosine rules.
- Vectors.
- Algebraic proof.
- Iteration.
- Functions and transformations of graphs.
- Histograms with unequal class widths.
- Conditional probability.
- Surds and rationalising.
- Circle geometry (equation of a circle, tangent to a circle).
Tracking Your Progress
Create a Grade Tracker
After each practice paper, plot your score and estimated grade:
| Paper | Date | Score (/80) | Running Total (/240) | Estimated Grade |
|---|
| Practice P1 | 1 Mar | 48 | — | — |
| Practice P2 | 8 Mar | 55 | — | — |
| Practice P3 | 15 Mar | 52 | 155 | Grade 7 |
Use historical grade boundaries to estimate your grade. Track the trend — are you improving?
Adjust Your Strategy
- If your score is stuck, focus on your weakest topic area.
- If your score is close to the next grade boundary, identify which types of questions could push you over.
- If you are consistently exceeding your target, consider aiming higher.
The Overlap Zone
Both Foundation and Higher cover grades 4 and 5 in the overlap zone.
| Foundation | Higher |
|---|
| Grade 5 | Very hard to achieve (top marks needed) | Achievable with the first half of the paper |
| Grade 4 | Solid middle performance | Minimum achievement |
