Required final score91.67%

The required final score is the percentage needed on the remaining assessment to reach your target overall grade. The range check shows whether that score falls within 0–100%.

Method

Required remaining score = [target − current score × (completed weight/100)]/(remaining weight/100). Completed weight + remaining weight = 100%.

How this calculation works

Work backwards from a desired overall course percentage to the score needed on the remaining assessment. Enter your average on completed work, not its already-weighted contribution, and ensure completed and remaining weights total 100%. The required score can expose a target that is already secured or impossible without extra credit.

Required remaining score = [target − current score × (completed weight/100)]/(remaining weight/100). Completed weight + remaining weight = 100%.

Worked example

This example uses illustrative inputs. Your current result is shown above.

A current score of 75% over 70% of the course contributes 75 × 0.70 = 52.5 points. For an 80% target and a 30% final, required score = (80 − 52.5)/0.30 ≈ 91.67%.

Assumptions and limits

  • Completed and remaining weights are positive and sum to 100%.
  • The same percentage score is assumed across the combined remaining assessment weight.
  • The feasibility flag tests whether the required score itself lies between 0% and 100%; extra credit, minimum exam passes and grade curves are not modelled.

Questions people ask

What does a required score above 100% mean?

Under the entered weights, the target cannot be reached with ordinary scores up to 100%. Confirm the inputs before considering whether your course has separate extra-credit or resit rules.

What does a negative required score mean?

The completed contribution already meets the target even with zero on the remaining component. The result is arithmetic; separate compulsory-pass requirements may still apply.
