How to calculate test score?

It is very simple to calculate the test score. To calculate the percentile test score, all you need to do is divide the earned points by the total points possible. To simplify it further, you just want to find out your grades or percentage of the correct answers.

percentage score = #correct / #total

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

percentage score = (#total – #wrong) / #total

Once you are done calculating the percentage of your correct answers, you need to convert them into a letter grade for more clarity as many teachers use the letter grade.

If you don’t use 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, an F is 59% and below – and it’s not a passing grade

The grading system mentioned above is a standard with the universities and schools of the US, however, it doesn’t imply that all schools, colleges and universities worldwide use the same conversion scale. The grading scale varies from school to school and your teacher might be using just any of it, depending on the grading scale.

As a student, you must know which grading scale is being used by your teacher, in order to be more adept to calculating your grades and deducing your performance and position in the class. At times, 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 grades!
