WASSCE Grade Interception


For instance, to get an A in WAEC 2020 English language, you need to score above 75% in the Exam. 75% means you are able to get 75 questions correctly out of 100 questions.

If you are given 50 questions in a subject, 75% is equal to around 37 questions you answered correctly. This explanation also applies to other grades above.

How is WAEC Percentage Grade Calculated?

To know whether you will score An A, B or C, divide the number of questions/marks you think you would get correctly by the total number of questions/marks possible and multiply by 100 percent.

Example: If you were able to answer 40 questions correctly out of 60 total questions given in Oral English. To calculate your percentage, it will be (40/60)x100% = 66.67% = B3.

In an objective, all questions carry equal marks.

For WAEC Theory Questions

Calculate how many marks you are very sure of, then divide by the total marks the questions carry and multiply by 100%.

Example: You are required to answer 5 questions in the theory section. Each question carries 20 marks.

Let’s say you are able to answer 4 questions and sure of 15 marks out of a total of 20 marks for each question.

The total marks you are sure of is 15×4 = 60

Total number of marks you can get is 20×5 = 100

Your percentage score is (60/100)x100% = 60% = C4
