How to calculate test score

To calculate the percentile test score, all you need to do is divide the earned points by the total points possible. In other words, you're simply finding the percentage of good answers:

percentage score = (#correct / #total) × 100

As #correct + #wrong = #total, we can write the equation also as:

percentage score = 100 × (#total - #wrong) / #total

Then, all you need to do is convert the percentage score into a letter grade. The default grading scale looks as in the table below:

Letter grade

Percentile

A+

97-100

A

93-96

A-

90-92

B+

87-89

B

83-86

B-

80-82

C+

77-79

C

73-76

C-

70-72

D+

67-69

D

63-66

D-

60-62

F

Below 60

If you don't like using the +/- grades, the scale may look like:

  • An A is 90% to 100%;
  • A B is 80% to 89%;
  • A C is 70% to 79%;
  • A D is 60% to 69%; and finally
  • F is 59% and below – and it's not a passing grade

Above, you can find the standard grading system for US schools and universities. However, the grading may vary among schools, classes, and teachers. Always check beforehand which system is used in your case.

Sometimes the border of passing score is not 60%, but, e.g., 50 or 65%. What then? We've got you covered – you can change the ranges of each grade! Read more about it in the last section of this article: Advanced mode options.

Test grade calculator – how to use it?

Our test score calculator is a straightforward and intuitive tool!

  1. Enter the number of questions/points/problems in the student's work (test, quiz, exam – anything). Assume you've prepared the test with 18 questions.

  2. Type in the number the student got wrong. Instead – if you prefer – you can enter the number of gained points. Let's say our exemplary student failed to answer three questions.

  3. Here we go! Teacher grader tool shows the percentage and grade for that score. For our example, the student scored 83.33% on a test, which corresponds to a B grade.

  4. Underneath you'll find a full grading scale table. So to check the score for the next students, you can type in the number of questions they've got wrong – or just use this neat table.

Test grade calculator – advanced mode options

That was a basic version of the test grade calculator. But our teacher grader is a much more versatile and flexible tool!

You can choose more options to customize this test score calculator. Just hit the Advanced mode button below the tool, and two more options will appear:

  1. Increment by box – Here, you can change the look of the table you get as a result. The default value is 1, meaning the student can get an integer number of points. But sometimes it's possible to get, e.g., half-points – then you can use this box to declare the increment between the next scores.

  2. Percentage scale – In this set of boxes, you can change the grading scale from the default one. For example, assume that the test was challenging and you'd like to change the scale so that getting 50% is already a passing grade (usually, it's 60% or even 65%). Change the last box, Grade D- ≥ value, from default 60% to 50% to reach the goal. You can also change the other ranges if you want to.

And what if I don't need +/- grades? Well, then just ignore the signs 😄

Is 27 out of 40 a passing grade?

This depends mainly on the grading scale that your teacher is using. If a passing score is defined as 60% (or a D-), then 27 out of 40 would correspond to a 67.5% (or a D+), which would be a passing grade. However, depending on your teacher’s scale, the passing score could be higher or lower.

What grade is 7 wrong out of 40?

This is a B-, or 82.5%. To get this result:

  1. Use the following percentage score formula:
    percentage score = 100 × (#total - #wrong) / #total

    Here, #total represents the total possible points, and #wrong, the number of incorrect answers.

  2. Substitute your values:
    percentage score = 100 × (40 - 7) / 40
    percentage score = 82.5%

  3. Convert this percentage into a letter grade. In the default grading scale, 82.5% corresponds to a B-. However, grading varies — make sure to clarify with teachers beforehand.

Is 75 out of 80 an A?
