How It Works
How to Calculate Test Score Average
The test score average is the arithmetic mean of all test scores.
Formula
Average = (Test 1 + Test 2 + ... + Test N) / N
This gives equal weight to every test.
Worked Example
A student has four test scores: 85, 92, 78, 88.
test1 = 85test2 = 92test3 = 78test4 = 88
- 01Sum = 85 + 92 + 78 + 88 = 343
- 02Average = 343 / 4 = 85.75
- 03Range = 92 - 78 = 14
Frequently Asked Questions
Should I drop my lowest test score?
Some instructors allow dropping the lowest score. Check your syllabus. If allowed, remove the lowest before averaging.
How does one bad test affect my average?
One low score pulls the average down proportionally. With 4 tests, each contributes 25% to the average.
Is a weighted test average different?
Yes, weighted averages count some tests more heavily. A midterm worth 30% counts more than a quiz worth 10%.
