How to Drop the Lowest Quiz in a Grade Calculator
If you’ve ever wanted to drop your lowest quiz score when calculating your grade, you’re in the right place. Whether you’re using an online grade calculator or doing it by hand, Quick Grade, this guide breaks it down in the simplest way — like I’m explaining it to a friend.
Dropping the lowest quiz can help improve your average, especially if one quiz didn’t go well. Just make sure your syllabus or class grading rules allow it before you use this method.
What “Drop the Lowest Quiz” Means
When a grade calculator or gradebook drops the lowest quiz, it ignores the lowest score from the list before figuring out your average. This means that bad quiz won’t pull your average down.
For example, if your quiz scores are:
- Quiz 1 — 60%
- Quiz 2 — 80%
- Quiz 3 — 90%
…and you drop the lowest (60%), you would average only 80% and 90%, so your quiz average becomes (80 + 90) ÷ 2 = 85%.
This is usually done for fair grading because teachers want to give you a break on one bad day.
How to Do It in a Grade Calculator
Here’s the step-by-step process:
- List All Your Quiz Scores
Start by writing down each quiz score you got. Keep them in a list.
Example: 78, 92, 85, 66, 90 - Choose How Many to Drop
Decide how many lowest scores you’re allowed to drop. Most policies drop just one, but some drop more. Check your syllabus to be sure. - Sort the Scores
Put your quiz scores in order from lowest to highest: 66, 78, 85, 90, 92 - Remove the Lowest
Take out the lowest score(s): Drop 66 → Remaining: 78, 85, 90, 92 - Add the Remaining Scores
Add up the scores that are still counting: 78 + 85 + 90 + 92 = 345 - Divide by the Number of Scores Left
Divide by how many scores are left: 345 ÷ 4 = 86.25%
That’s it! You just dropped the lowest quiz. Simple math, big impact.
Extra Tips for Dropping the Lowest Quiz
- Always check your syllabus first. Some classes automatically drop lowest quizzes. Don’t assume.
- Use percentages, not raw points. If quizzes have different total points (like 20 vs 50), convert to percentages first.
- Only drop the number of scores allowed. Dropping extra scores may misrepresent your grade.
- Use an online calculator to save time. Free tools let you plug in numbers and drop lowest scores automatically.You can also read: How to Round Grades the Right Way 2026
