UK GCSE Grade Predictor
Welcome to the **most accurate** GCSE Grade Calculator. This tool is designed for students and teachers in the UK to predict final grades (1–9) using provisional exam scores, paper weightings, and official grade boundaries from all major exam boards (AQA, Edexcel, OCR, etc.). Simply enter your marks for each paper, adjust the weighting, and select your board to see your predicted overall percentage and final GCSE grade. Use this to focus your revision or track progress towards your target grade!

Frequently Asked Questions (FAQ)
The accuracy depends entirely on the **grade boundaries** you use. If you select the *'Latest Official Boundaries'*, the prediction is highly accurate, matching the methodology used by the exam boards. However, official boundaries are only released *after* the exams are sat. Using previous years' boundaries gives a strong estimate but is not guaranteed to be exact as boundaries change annually based on student performance.
The **Paper Score** is simply the percentage you achieved in that single paper (Marks Earned / Total Marks). The **Weighted Contribution** is the score's effect on your final grade, calculated by multiplying your Paper Score by the paper's percentage weighting. For example, a 60% on a 50% weighted paper contributes 30% (60% * 50%) to your overall score.
Not all exam papers are worth the same amount towards the final qualification. For instance, in some subjects, Paper 1 might be 35% and Paper 2 might be 65%. The weighting ensures that your marks are scaled correctly to reflect their true impact on your overall grade, which is essential for accurate prediction. **The total weighting for all papers must equal 100%.**
The 1–9 grading system replaced the old A*–G system in England. Grade 9 is the highest, roughly equivalent to a top A*, while Grade 4 is considered a 'standard pass' (roughly equivalent to a C). Grade 5 is a 'strong pass' (roughly equivalent to a high C/low B). The boundaries are the minimum total percentage required to achieve each specific grade.
Yes. For Combined Science, you will typically have six papers (two each for Biology, Chemistry, and Physics). You should add all six papers individually, ensuring the total weighting adds up to 100%. Combined Science results in two grades (e.g., 6-6 or 7-6), which are determined by the boundaries set for the overall aggregate score.
Mastering Your GCSEs: A Deep Dive into Grade Prediction and Calculation
Understanding how your GCSE grades are calculated is the first step toward achieving your target results. In the UK, the move to the 9–1 grading system, coupled with complex paper weightings and fluctuating grade boundaries, means a simple mental calculation is no longer enough. Our advanced calculator acts as your personal assessment tool, providing clarity and actionable insights into your performance. It demystifies the process by breaking down your raw marks into a final, predicted grade, allowing you to see exactly where you stand and how many more marks you need to jump to the next level.
How to Use the GCSE Grade Calculator: Step-by-Step Guide
Accuracy starts with the input. Follow these simple steps to ensure you get the most reliable prediction possible:
- Select Your Subject and Board: Start by choosing the specific GCSE subject (e.g., Mathematics) and the relevant Exam Board (AQA, Edexcel, OCR, etc.). This selection is crucial as different boards and subjects use entirely different mark schemes and boundaries.
- Input Exam Scores: For each paper, enter the **Marks Earned** and the **Total Marks** available. If your subject has more than two papers (like Combined Science or History), use the **'+ Add Additional Paper'** button.
- Verify Paper Weighting: This is the most critical step. Ensure the **Weight (%)** for each paper is correct. For many subjects, this is 50/50. However, always check the specification for your specific course. The total of all weightings *must* equal 100%.
- Choose Grade Boundaries: The default **'Latest Official Boundaries'** is the most accurate. If these are not yet released, use the previous year’s data or input custom boundaries if you have provisional data from your school.
- Calculate and Analyze: Press the **'Calculate'** button. The tool will instantly provide your overall percentage and your predicted grade, along with a detailed breakdown of your performance in each paper.
The Calculation Formula Demystified: Understanding Weighted Scores
The core logic of the calculator relies on a weighted average calculation. It's not enough to simply add all your marks and divide by the total possible marks, especially when paper weightings differ.
The formula for calculating the **Overall Weighted Score** is as follows:
$$ \text{Overall Score} = \sum_{i=1}^{n} \left( \frac{\text{Marks Earned}_i}{\text{Total Marks}_i} \times \text{Weight}_i \right) $$Where $i$ represents each paper, and $n$ is the total number of papers. For example, if you score 60/100 (60%) on Paper 1 (weighted 40%) and 80/100 (80%) on Paper 2 (weighted 60%):
- Paper 1 Contribution: $0.60 \times 0.40 = 0.24$ (or 24%)
- Paper 2 Contribution: $0.80 \times 0.60 = 0.48$ (or 48%)
- Overall Weighted Score: $0.24 + 0.48 = 0.72$ (or 72%)
This final 72% is then compared against the official grade boundaries to determine your predicted Grade 1–9. This weighted methodology ensures the grade reflects the true structure of the examination.
The Importance of Grade Boundary Calculations
Grade boundaries are the cut-off marks required for a student to achieve a particular grade. These are not fixed but are adjusted annually by examiners to ensure consistency in standards—meaning a Grade 7 this year represents the same level of achievement as a Grade 7 last year, even if the raw mark required is different.
When predicting your grade, the calculator uses the selected boundary data (e.g., AQA 2024 Grade Boundaries for English Literature). By knowing the exact percentage required for a Grade 8 and a Grade 7, the tool can provide the crucial **Proximity to Next Grade** statistic, showing you precisely how many marks you need to move up. This is the most powerful feedback a student can receive outside of official results.
