Dropping a quiz: percentage and points rules differ

Compare your average before and after dropping the lowest eligible percentages. Choose equal, pooled-points or renormalized-weight averaging.

Quiz percentages of 50%, 80% and 90% average 73.3333% when each quiz counts equally. Dropping the eligible 50% quiz leaves 85%. If quiz point totals differ, pooling points can produce a different before-and-after result.

Enter one graded group at a time. All rows need recorded scores; a recorded zero counts. Mark required assessments as Never drop. This tool drops lowest percentages, not the combination that maximizes a points-based average. Retained weights are renormalized. Blank future work, extra credit, dropped highest scores and category redistribution rules are not modeled.

A points total is not the same as an equal quiz average

An assessment out of 100 points counts ten times as much as one out of 10 in pooled-points mode. Equal-percentage mode gives each assessment the same influence. Select the method your syllabus uses before interpreting the improvement.

Why a low percentage may not be the score an LMS drops

With 50/50, 65/100 and 12/24, the lowest percentage is 12/24. Removing it gives 115/150, about 76.67%. Removing 65/100 instead gives 62/74, about 83.78%. Those are different rules; this tool deliberately applies the explicitly selected lowest-percentage rule.

Carry a group average into the full course carefully

If these are quizzes worth 20% of a course, the new quiz average is only that category’s average. Enter it with the category’s syllabus weight in the weighted grade calculator. It is not automatically your final course grade.
