Exam Mark Calculator

Find out exactly what mark you need in your remaining exam or component to hit your target overall grade. Enter completed components, their marks and weightings, and set your target.

What Mark Do I Need in My Exam?

Enter each completed component with its mark and weighting, then set your target overall percentage. The calculator tells you what you need in the remaining component.

Enter Completed Components

All weightings must add up to 100%. Enter the completed components below, leaving the remaining exam as the unfilled component.

The Formula: How to Calculate Required Exam Mark

To find what mark you need in a remaining component, use the following formula:

Required Mark = (Target% − Sum of Completed Marks × Their Weights) ÷ Remaining Weight

Where all weights are expressed as decimals (e.g., 30% = 0.30).

Worked Example

1
You scored 65% on your coursework, which is worth 30% of your overall grade.
2
Your target overall grade is 60%. The exam is worth the remaining 70%.
3
Completed contribution: 65 × 0.30 = 19.5
4
Remaining needed: 60 − 19.5 = 40.5
5
Required exam mark: 40.5 ÷ 0.70 = 57.9%

So if you scored 65% on coursework (30% weighting) and need 60% overall, you must score at least 57.9% in the exam (70% weighting). This is very achievable.

Impossible Targets: When the Maths Doesn't Work

Sometimes the formula returns a required mark above 100%. This means your target overall grade is mathematically impossible given your completed component results. This can happen if:

  • Your coursework or earlier components were significantly below your target
  • The completed components had high weighting and underperformed
  • Your target is very ambitious relative to your current performance
Coursework Mark Coursework Weight Target Overall Required Exam Mark Achievable?
65%30%60%57.9%Yes
45%30%70%80.7%Yes (hard)
30%30%60%72.9%Yes (very hard)
20%40%60%86.7%Very difficult
10%50%60%110%Impossible
25%60%55%101.5%Impossible
If your target is impossible, the best options are: lower your target grade, check whether mitigating circumstances apply, or speak to your teacher or personal tutor about your options. For university modules, an impossible target for a higher grade doesn't mean you will fail — calculate what you need to simply pass (40% or 50%) instead.

Applying the Calculator to Different Qualifications

GCSE Coursework and Controlled Assessment

Most current GCSE subjects are assessed entirely by examination, but some include a non-exam assessment (NEA) or coursework element:

  • GCSE Art and Design: 60% portfolio, 40% exam
  • GCSE Drama: 40% devising, 20% performance, 40% written exam
  • GCSE Music: 30% performance, 30% composition, 40% listening exam
  • GCSE PE: 40% practical, 60% written exam
  • GCSE English Language: Spoken language endorsement (pass/merit/distinction) — assessed separately, does not affect overall grade

For these subjects, if your coursework mark is confirmed, you can calculate exactly what exam mark you need for each grade boundary.

A-Level Non-Exam Assessment (NEA)

A-Level subjects with NEA components typically weight the NEA at 20–25% of the total grade. Examples:

  • A-Level Biology: 100% exam (no NEA at many boards)
  • A-Level Art: 60% personal investigation, 40% exam
  • A-Level Geography: 20% NEA (fieldwork report), 80% exams
  • A-Level History: 20% NEA (historical investigation), 80% exams
  • A-Level Music: 30% performance, 25% composition, 45% written exam

University Module Assessments

University modules commonly split assessment between coursework, essays, presentations, and exams. A typical split might be:

  • Coursework: 30% — Essay: 30% — Exam: 40%
  • Lab Report: 20% — Mid-term test: 20% — Final exam: 60%
  • Dissertation/Project: 100% (some modules assessed entirely by one component)

If you have completed your coursework and essay, you can use this calculator to find the exact exam mark needed for your target classification (First, 2:1, etc.).

Risk Assessment: Minimum Effort vs Target Grade

A valuable use of this calculator is exploring different scenarios — what mark do you need for your ideal grade, and what mark do you need just to pass? This helps you plan your revision effort strategically.

The Minimum Pass Scenario

If you are confident in your current performance but worried about one component, calculate the minimum mark you need to pass overall. For most university modules, passing requires 40%. For GCSE, a grade 4 requires approximately 40–50% overall. Knowing this minimum gives you a safety floor below which you must not fall.

The Stretch Target Scenario

Equally, calculate what mark you need for your stretch target (e.g., a First or grade 9). If this requires 95% in the exam after a strong coursework mark, you know where to focus your revision energy.

Multiple Components

If you have two remaining components (e.g., two exam papers), this calculator assumes all remaining weighting goes into one component. For multi-component situations, use the calculator iteratively — calculate for Paper 1, then adjust the target and recalculate for Paper 2 based on your Paper 1 result.

Alternatively, set a combined target for all remaining components: if you need 65% across two equally-weighted papers (each 35% of the total), aim for 65% on average across both papers, then allocate revision time based on your relative strengths in each.

Frequently Asked Questions

How do I calculate what mark I need in my exam?
Use the formula: Required Mark = (Target% − Sum of Completed Mark × Weight) ÷ Remaining Weight. For example, 65% on coursework (30% weight), target 60% overall: (60 − 65×0.30) ÷ 0.70 = (60 − 19.5) ÷ 0.70 = 57.9%. You need at least 57.9% in the exam.
What if the required exam mark comes out above 100%?
If the calculation gives a result above 100%, your target grade is mathematically impossible to achieve given your completed component results. Lower your target to a more realistic grade and recalculate, or speak to your teacher or tutor about your situation. Mitigating circumstances may be relevant if poor performance was due to extenuating factors.
What percentage weighting does an A-Level exam typically carry?
Most A-Level subjects are assessed 100% by written examination, with no coursework. Where a Non-Exam Assessment (NEA) exists, it typically accounts for 20–25% of the total grade, leaving 75–80% for written exams. Check your specific subject specification on the exam board website for exact weightings.
How do university module weightings work?
University modules typically combine coursework, essays, presentations, and exams, each with a stated weighting. For example, a module might be 30% coursework and 70% final exam. The overall module mark is the weighted average of all components. Check your module handbook or virtual learning environment (Moodle, Blackboard, Canvas) for specific weightings.
What is the minimum exam mark needed to pass a university module?
For undergraduate modules, the pass mark is typically 40%. However, some modules require a minimum mark in individual components — for example, you may need to achieve at least 35% in the exam itself, regardless of your coursework mark. Some professional courses have even higher minimums. Check your module handbook carefully.
Can a strong coursework mark compensate for a weak exam?
In most UK schools and universities, overall module marks are calculated by weighting all components together, so strong coursework can compensate for a weaker exam mark. However, if any component has a mandatory minimum mark requirement (which some university modules do), compensation is not unlimited. Always check the rules for your specific module or subject specification.
