The grading system in Waec is the same for almost all subjects, with the exception of a few subjects. According to the waec rating system, a candidate who wishes to obtain A1 in a subject is expected to score between 75% and 100%.
Similarly, a candidate who obtains a percentage mark from 70% to 74% is graded on B2 in the said subject. You can read more about the new WAEC classification system here. You can also check to see how your WASSCE score is calculated.
How Does WAEC Calculate Percentage Score?
The percentage scored in a subject is calculated using the raw scores obtained in the subject divided by the total number of scores assigned and multiplied by 100.
Assuming that the candidate was able to obtain 70 marks out of a total of 100 marks in Mathematics Optional Paper 2 (Theory), the same candidate also scored 34 out of the 40 objective questions.
What the examinees will do is take the marks to get (70) and divide it by the total marks allocated (100). This is done to check your score in theory.
After confirming your score theoretically, this score will be added to the scores you obtained in the other objectives to get the overall final score.
Marks Obtain in Theory = 70
Total Marks allocated for theory questions = 100
Total Marks Allocated for objectives = 40
Marks Obtain in Objective = 34
Total Marks obtain By Candidate = 70 + 34
Total Allocated Marks (Both Objective & Theory) = 100 + 40
=> 104/140 X 100 = 74.3%
Going with the grading system, this candidate has obtained A1 in Elective maths.
