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

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

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