Exam Marks Calculator: Find the Final Score You Need

Use the exam marks calculator

How to use the exam marks calculator

1. Convert your internal marks to a percentage if necessary. For example, 24 out of 30 is 80%.
2. Enter the percentage of the overall result assigned to internal assessment. The remaining weight is assigned to the final exam.
3. Enter the overall course percentage you want to reach.
4. Enter the maximum marks available in the final exam, such as 70 or 100.
5. Read the required final marks and the feasibility message. Check any separate final exam pass mark, then download or print your plan.

Formula and calculation method

Required final exam (%) = [target overall (%) − internal score (%) × internal weight ÷ 100] ÷ (1 − internal weight ÷ 100). Required final marks = required final exam (%) × exam maximum ÷ 100.

Worked example

An internal score of 80% contributes 40% of the overall grade. To finish with 75% overall, the final exam percentage must be (75 − 80 × 0.40) ÷ 0.60 = 71.666…%. For a 100-mark exam, the calculator displays at least 71.67 marks. If marks are awarded only as whole numbers, plan for at least 72.

Internal percentages and raw marks are different

An internal score of 24 out of 30 is 80%, not 24%. Similarly, a final examination worth 70 raw marks can still contribute 60% of the course result. Enter the score, weighting and examination maximum in their separate fields to avoid mixing these quantities.

Check whether the target is achievable

If the calculation requires more than the maximum final marks, the target cannot be reached using the entered scores and weights. A target already secured by internal assessment does not automatically mean you can skip the final exam or ignore a separate passing requirement.

What this weighted score model leaves out

The formula combines two components: internal assessment and a final exam. It does not apply grade boundaries, minimum component scores, moderation, bonus marks or rounding policies automatically. If a course has several internal components, combine them using their official weights before entering the internal percentage.

Frequently asked questions

Should I enter internal marks or internal percentage?

Enter the internal percentage. Divide marks earned by the maximum internal marks and multiply by 100 first.

What if the exam awards whole marks only?

Round the required marks upward to the next permitted mark increment. For example, a requirement of 71.67 needs 72 if only whole marks are awarded.

Can this confirm that I will pass?

No. It estimates the marks for an overall target under the entered weighting. Separate component pass marks and other institutional rules can still apply.
