Dropped Assignment Average Calculator
Remove the lowest of five comparable percentage scores and compare the resulting average with the original five-score mean.
Enter five comparable scores
Eligibility matters before arithmetic
A syllabus may exclude exams, require submission before a score can be dropped, or drop within categories rather than across the whole course.
Verify that each entered score belongs to the same drop pool.
A companion calculation can handle a larger assignment record.
Verify drop eligibility
- Confirm five scores share one weighting rule.
- Identify any non-droppable work.
- Remove one lowest eligible score.
- Recalculate the category before applying its course weight.
Arithmetic behind the result
Interpretation: The calculation assumes five equally weighted, eligible assignments and drops exactly one lowest percentage.
Percentage averaging can mislead when points differ
A 90% on a ten-point quiz and 70% on a hundred-point exam are not equally weighted in a points-based course.
When assignments carry different points, apply the drop to earned and possible points under the actual policy.
The work can also measure how a new score changes a points-based course.
Document the dropped item
Save the assignment name, original score, category, and policy clause that made it eligible. The resulting average alone cannot show whether the correct item was removed.
If a later score becomes lower, the gradebook may change which assignment is dropped. Recalculate from the full eligible set rather than treating the first dropped item as permanent.
Dropping the lowest percentage does not always maximize a course grade when assignments have different weights, late penalties, or category rules. Confirm that the policy itself selects by percentage and that all five entries contribute equally before using the four-score average.
If the drop is conditional on completing every assignment, a missing submission may remain a zero rather than being eligible. Preserve that condition beside the calculation.
After applying the drop, preserve the remaining four raw scores rather than recording only their average. Later corrections, appeals, or another eligible assignment may change which score should be omitted.
If the gradebook rounds each assignment before averaging, retain the unrounded source scores separately so any small discrepancy with the displayed course result can be explained.
Clarifying the inputs
What happens when two scores tie for lowest?
Dropping either produces the same numerical average.
Can a missing assignment be dropped?
Only when the policy allows it and the missing work is represented by the appropriate score.
Dropping one of five scores
Scores of 78, 92, 84, 65, and 88 average 81.4%. Dropping the 65% raises the four-score average to 85.5%, an increase of 4.1 points.
