The quick guide
Understand the result
The calculator compares your target total with the marks already secured and the marks still available.
Example
With 42 marks from 50 completed marks, a remaining exam worth 50 marks, and a 75% target, the required mark is (75 × 100 ÷ 100) − 42 = 33 marks.
Use it as a planning estimate
Achievable does not mean guaranteed
An achievable result means the required marks fit within the remaining exam maximum. Your institution may apply additional rules such as grade boundaries, rounding, moderation, or separate pass requirements.
FAQ
What does “already effectively achieved” mean?
It means the marks already obtained are enough to meet or exceed the target when the remaining exam is included. The calculator shows 0 required marks; you may still need to complete the exam for your course.
When is a target impossible?
A target is impossible when the required marks are greater than the maximum available in the remaining exam. This calculation does not assume extra assessments beyond the values you enter.
Can I enter decimal marks?
Yes. Decimal values are accepted when your course records marks that way. All values must be finite, non-negative, and within their relevant maximums.
