How to Use the Eduqas Biology Grade Calculator
A complete guide to understanding your results, analysing mock exams, and planning resits with our free Eduqas A-Level Biology tool.
Which Tool Should I Use?
The Eduqas Biology Grade Calculator has two main tools, each designed for different situations:
| Tool | When to Use | What It Does |
|---|---|---|
| 📊 Results Analyser | Results day, or when planning resits | Enter your actual exam marks, see your grade, and calculate what you’d need if resitting |
| 🔍 Mock Exam Analyser | After mock exams, during revision | Enter mock scores to predict your grade and identify areas to improve |
Understanding Raw Marks & Percentages
Eduqas A-Level Biology uses raw marks only (no UMS conversion like WJEC). Here’s what you need to know:
- Raw Marks
- The actual marks you score on each exam paper. Each component is worth 100 marks, giving a total of 300 marks for the whole qualification.
- Percentage
- Your raw marks expressed as a percentage. Since each component is out of 100, your raw mark equals your percentage for that component.
- Grade Boundaries
- The minimum total raw marks needed for each grade. These are set after marking is complete and vary each year depending on exam difficulty.
The Three Components
| Component | Name | Marks | Duration |
|---|---|---|---|
| 1 | Energy for Life | 100 | 2 hours |
| 2 | Continuity of Life | 100 | 2 hours |
| 3 | Requirements for Life | 100 | 2 hours |
| Total | 300 | 6 hours | |
Using the Results Analyser
Use this tool on results day or when you have your actual exam marks. It shows your grade and helps you decide whether resitting is worthwhile.
Select Your Exam Year
Choose the year you sat your exams (2022–2025). This determines which grade boundaries are used.
Choose Your Target Grade
Select the grade you’re aiming for. The tool will show how far you are from achieving this.
Select Input Type
Choose whether to enter Raw Marks or Percentages. Since each component is out of 100, these are effectively the same.
Enter Your Component Marks
Input your marks for Component 1, 2, and 3. These should be from your official results.
Click “Analyse My Results”
The tool will calculate your total, show your grade, and display how close you are to each grade boundary.
Understanding Your Results
After analysis, you’ll see:
- Total Raw Marks: Your combined score out of 300
- Your Grade: The grade you achieved based on this year’s boundaries
- Target Status: How many marks you need for your target grade (or confirmation you’ve achieved it)
- Component Breakdown: Your performance in each paper with notional grades
- Grade Boundaries: How your marks compare to each boundary
Using the Resit Impact Calculator
The Resit Calculator appears after you’ve analysed your results. It helps you determine whether resitting would be worthwhile.
First Complete the Results Analysis
Enter your current marks and click “Analyse My Results” to see your grade.
Enter Predicted Resit Marks
In the Resit Impact Calculator section, enter your predicted marks for ALL 3 components. Be realistic about what you could achieve with additional study.
Click “Calculate Resit Impact”
The tool shows whether resitting would improve your grade and help you reach your target.
When Is Resitting Worth It?
Consider resitting if:
- You were close to a grade boundary and believe you can improve significantly
- You had circumstances that affected your performance (illness, etc.)
- You need a specific grade for university entry
- You’re prepared to study all topics again, not just weak areas
Be cautious about resitting if:
- You would need to take a gap year
- Your marks are already strong and improvement is marginal
- You struggled with all components equally
Using the Mock Exam Analyser
Use this tool after a mock exam to see your notional grade for that component. Analyse one mock at a time to track your progress.
Select the Component
Choose which component’s mock you’re analysing (Component 1, 2, or 3).
Select Grade Boundaries Year
Choose which year’s boundaries to compare against. 2025 is most recent.
Choose Your Input Type
Select Percentage or Raw Marks depending on how your mock result was given.
Enter Your Mock Score
Input your score for the selected component.
Click “Analyse My Mock”
The tool shows your notional grade for that component, how many marks to the next grade, and the full grade boundaries for comparison.
Tips & Common Questions
Boundaries are set after marking to ensure consistent standards. If a paper is harder than usual, boundaries are lowered so students aren’t disadvantaged. The 2022 boundaries were notably lower due to pandemic-related adjustments.
Use the year you sat (or will sit) your exams. For mock analysis, the most recent year (2025) gives the best indication, but checking multiple years shows how boundaries vary.
Eduqas publishes component-level boundaries for guidance, but only the overall total determines your final grade. A “notional A” on one component doesn’t guarantee an A overall.
For actual results, the tool is completely accurate — it uses official Eduqas boundaries. For mocks, accuracy depends on how representative your mock papers were of real exams.
Official boundaries are published on the Eduqas website after each exam series. You can also use the WJEC/Eduqas Mark Converter for interactive boundary lookup.
