Why a quiz average matters

In most syllabi the quiz category is one of the smaller weights (10–15% is typical), but consistent quiz performance often decides the difference between a B+ and an A−. Tracking your quiz percentage week by week tells you whether you need to change your study habits before the bigger exams.

Step-by-step

  1. Add a row for each quiz the instructor has graded.
  2. Enter the points you scored.
  3. Enter the maximum points for that quiz.
  4. Read the running average in the result tiles.

Drop policies and the right way to handle them

Many instructors drop the lowest one or two quiz scores at the end of the semester. To preview your post-drop quiz average, simply leave the lowest row(s) out of the calculator. To plan for an upcoming quiz, add a row with a target score and watch how the average shifts.

Frequently asked questions

How do I find my quiz average?

Add up all the points you scored across every quiz, divide by the total maximum points possible, multiply by 100.

What if my instructor drops the lowest quiz?

Simply omit that row from the calculator. The remaining quizzes will give you the post-drop average.

Are pop quizzes the same?

Yes — the math is the same regardless of whether the quiz was scheduled. Add a row for each one.
