For long tests, it might be easier to subtract the number of questions you got wrong from the total number of questions on the test. For example, if you got 5 questions wrong on a 26-question test, subtract 5 from 26 (26 - 5 = 21). Then, use 21 as the top number in your fraction. If some questions are worth more points than others, use the total number of points you earned as your top number instead. For example, if you earned 53 points out of 70 points possible, then write 53 as your top number.

Check your fraction to make sure that it is set up correctly. Remember that the number of questions you got right or the number of points you earned should be on the top of the fraction. The total number of questions on the test or the total number of points possible should be at the bottom of the fraction.

Don’t worry about the numbers past the first four digits of the answer. For example, if the answer was 0. 8077777, then you can just ignore the last three sevens. They will not affect your percentage.

Depending on your teacher’s grading scale, 80. 77% would be a B or a B-.

An “A” is 90% to 100%. A grade of 100% is an “A+”. A grade of 94%-99% would be considered an “A. ” A grade of 90%-93% would be considered an “A-. ” A “B” is 80% to 89%. A grade of 87% or higher would be considered a “B+. ” A grade of 83%-86% would be considered a “B. ” A grade of 80%-82% would be considered a “B-. ” A “C” is 70% to 79%. A grade of 77% or higher would be considered a “C+. ” A grade of 73%-76% would be considered a “C. ” A grade of 70%-72% would be considered a “C-. ” A “D” is 60% to 69%. A grade of 67% or higher would be considered a “D+. ” A grade of 63%-66% would be considered a “D. ” A grade of 60%-62% would be considered a “D-. ” An “F” is 59% and below. An “F” is a failing grade, so professors and teachers do not usually assign + or – values to “F” grades. [4] X Research source
