How This Calculator Works
Many GCSE and A Level subjects split your final grade between coursework (often called NEA or Non-Examined Assessment) and written exams. This calculator takes your coursework mark, applies its weighting, and works backwards to tell you exactly what percentage you need in the exam component to hit your target grade overall.
CW Contribution = (CW Mark / CW Max) x CW Weight
// Step 2: Work out how much the exams need to contribute
Exam Needed = Target Grade % – CW Contribution
// Step 3: Convert to a percentage on the exam itself
Required Exam % = Exam Needed / Exam Weight x 100
// Step 4: Convert to raw marks if max is provided
Required Raw Mark = (Required Exam % / 100) x Exam Max Marks
// Example: CW 38/60 (63.3%) at 40% weight, target Grade 6 (60%)
CW Contribution = 63.3% x 0.40 = 25.3%
Exam Needed = 60% – 25.3% = 34.7%
Required Exam % = 34.7 / 60 x 100 = 57.8%
Which UK Subjects Have Coursework?
Not all GCSE and A Level subjects include a coursework or NEA component. Here is a reference for common subjects and their typical splits.
| Subject | Level | Coursework weight | Exam weight | Coursework type |
|---|---|---|---|---|
| English Literature | GCSE | 20-25% | 75-80% | Written assignment |
| English Literature | A Level | 20% | 80% | NEA essay |
| History | A Level | 20% | 80% | Historical investigation |
| Geography | A Level | 20% | 80% | Independent investigation |
| Art and Design | GCSE | 60% | 40% | Portfolio |
| Art and Design | A Level | 60% | 40% | Personal investigation |
| Business Studies | A Level | 20% | 80% | Written investigation |
| French / Spanish | A Level | 20-25% | 75-80% | Speaking NEA or oral |
| Drama | GCSE | 40-60% | 40-60% | Practical performance |

Weightings vary by exam board. Always check your specific specification for the exact split.
Table of Truth: Worked Examples
| CW Mark | CW Max | CW Weight | Target | CW Contribution | Required Exam % |
|---|---|---|---|---|---|
| 38/60 | 60 | 40% | GCSE 6 (60%) | 25.3% | 57.8% |
| 45/60 | 60 | 40% | GCSE 7 (70%) | 30.0% | 66.7% |
| 50/60 | 60 | 40% | GCSE 8 (80%) | 33.3% | 78.3% |
| 32/50 | 50 | 20% | A Level B (70%) | 12.8% | 71.5% |
| 40/50 | 50 | 20% | A Level A (80%) | 16.0% | 80.0% |
| 22/50 | 50 | 20% | A Level C (60%) | 8.8% | 63.8% |
Why Coursework Can Make or Break Your Grade
Students often underestimate how much their coursework mark shifts what they need in the exam. A strong coursework score provides a cushion. A weak one forces you to overperform in the exam hall.
The cushion effect
If your subject is 40% coursework and you score 90% on your NEA, you have already banked 36% of your final grade. In an exam worth 60% of the grade, you only need 40% to achieve a Grade 6 overall. That is a generous exam target compared to someone who scored 60% on coursework and needs 60% in the exam to reach the same overall grade.
The drag effect
The reverse is equally powerful. A 40% coursework score on a 40%-weighted NEA contributes just 16% to your final grade. To reach Grade 7 overall (70%), you need the exam to contribute 54%, which means scoring 90% on an exam worth 60% of your total. That is a very high bar.
Common Mistakes Students Make
Using the wrong weighting
AQA English Literature has a different coursework weight than Edexcel English Literature. Always check your specific exam board specification, not a general guide. The weighting is stated clearly in the “scheme of assessment” section of your spec document.
Confusing raw marks and percentages
A coursework mark of 40 out of 60 is 66.7%, not 40. Enter the raw mark and the maximum in this calculator and it will handle the conversion. Do not type your raw mark into the percentage field.
Forgetting that practical endorsements are separate
In Biology, Chemistry, and Physics A Level, the practical endorsement is assessed separately and reported as pass or fail. It does not contribute to your letter grade percentage. Do not include it as a coursework component in this calculator.
