Find out how your internal assessment score contributes to your final grade.
Contribution To Final Grade
22 pts
Out of a possible 25 points from internals.
Internal assessments (assignments, class tests, attendance-linked marks, practicals) are usually scored out of their own small total, then that score is scaled to count for a fixed percentage of your final grade โ commonly 20% or 25%. This calculator converts your raw internal score directly into its actual contribution.
This is useful for knowing exactly how much of your final grade is already "locked in" from internals before your main exam even happens.
Formula
Contribution to Final Grade = (Marks Obtained รท Maximum Internal Marks) ร Internal Weight %
The result tells you how many of the total grade percentage points your internal score has secured.
Worked Example

Use this to plan the final exam
Once you know your locked-in internal contribution, you can work backwards: subtract it from your target overall grade, and you know exactly how many percentage points you still need from the remaining exam component.
Different subjects, different weights
Internal weightage isn't always the same across every subject or course โ always confirm the exact percentage your specific course allocates to internal assessment before relying on this calculation for exam planning.
Frequently Asked Questions
How do internal marks convert to my final grade?
Divide your internal marks obtained by the maximum internal marks, then multiply by the percentage weight internals carry toward your final grade.
What if internals are worth 20% instead of 25%?
Just enter 20 as the weight instead โ the formula adjusts automatically to whatever percentage your course actually uses.
How do I know how many more marks I need overall?
Subtract your internal contribution from your target overall grade โ the remainder is what you need to earn from the rest of your assessments, like the final exam.
