You have just taken a test and you know how many questions you got wrong. To find out your grade, you need to figure out what percentage of questions you get right. To know your grade, you just need to know how many questions there were in total and how many questions you got right. This article explains how you can calculate your grade in different ways.

To step

Method 1 of 3: Calculate your grade based on the number of questions

1. Write down the total number of questions for the test. Put this number under the fraction line.
   • Suppose there were 26 questions. Then put this number under the fraction line.
2. Calculate the number of questions you got wrong. Subtract the number of incorrect questions from the total number of questions. Place the outcome above the fraction line.
   • Suppose you get 5 of the 26 questions wrong. Then you have 26 - 5 = 21 questions correct.
3. Calculate the fraction so that you get a decimal number.
   • In the example, you do the following: 21/26 = 0.8077 (rounded to 4 decimal places).
4. Multiply the answer by 100. Do the final answer from the previous step times 100 to get a percentage. # * In the example, you would do 0.8077 times 100 to get 80.77. If you want to round to whole percentages, that becomes 91. You always round to the nearest whole number. So from 80.50 you would round to 81, but from 80.40 you would round down to 80.
   • What you do by multiplying the decimal by 100 is basically shifting the decimal two places to the right. So 0.8077 becomes 80.77.

Method 2 of 3: Calculate the percentage per question by means of cross multiplication

1. Write down the number of questions in the test. For example, if the test had 15 questions, write that number below the fraction line.
2. Write a 1 above the score line. This way you calculate what percentage one question out of 15 will be.
3. Write a "=" sign after the fraction. This is necessary for cross multiplication.
4. After the "=" sign, add another fraction line with 100 below the line and "x" above the line. We want to calculate the "x".
   • Your equation now looks like this: 1/15 = x / 100.
5. Now we are going to do cross multiplication. Multiply the top number on the left by the bottom number on the right. Multiply the bottom number on the left by the top number on the right.
   • Your equation now looks like this: 100 = 15x. You do 100 times 1 and 15 times "x".
6. Isolate "x" by dividing. Divide both sides by 15, because 15 is next to the "x".
   • In this case, you divide both sides by 15.100 / 15 = 6.67 (rounded) and 15x / 15 = x. So you now get 6.67 = x, or x = 6.67.
7. Multiply the percentage per question by the number of correct questions. So if you got 13 questions right, you would do 13 times 6.67 to get 86.71. Rounded off to a whole number, this is 87.

Method 3 of 3: Convert the grade from "largely unsatisfactory" to "very good"

1. Sometimes no grades are given, only grade categories.
2. Ask your teacher which categories you work with.
3. Often you have the following categories with the corresponding grades (this can differ per school and per teacher)
   • More than insufficient is a 4.5 or lower.
   • Insufficient is between 4.5 and 5.5.
   • Sufficient is between 5.5 and 6.5.
   • Good is between 6.5 and 7.5.
   • Very good is a 7.5 or higher.
4. Check which category your grade belongs to.
   • For example, if you have a 6.2, it will be classified as Pass.

Tips

• Some calculators have a button for entering fractions and converting them to decimal places.

Warnings

• You easily make calculation errors when calculating your grade. So always check yourself an extra time. This way you can avoid a lot of difficulties!
