In this article, we shall discuss the WAEC Grading system 2022/2023, what it is all about, and how to calculate WAEC grades or score this year.

We will also show you all you need to know about WAEC Grading System 2022/2023, WAEC Grading points, and How WAEC Score Is Calculated.

After writing your WAEC examination, the next thing is to know how the WAEC score is calculated or graded.

You’ll also know what these marks; A1, B2, B3, C4, C5, C6, E8, D7, and F9 mean in WAEC.

If you have a D7 or B2 or A1 in either Mathematics, English, Chemistry, Physics, Biology, Government, or Literature in your WAEC result, you will understand what it means below;

WAEC Grading System 2022/2023 and How WAEC Score Is Calculated, how to calculate WAEC Score for 2022/2023 has been released by WAEC Board.

WAEC Grades Numeric Value Meaning



Universities that compute an aggregate score for students using their O’ level result (WAEC, NECO, and NABTEB), grades individual grade for each subject as thus;


WAEC Grade Value Point
A1 10
B2 9
B3 8
C4 7
C5 6
C6 5

Universities O’level aggregate grading system

D7, E8, and F9 are not considered as pass by any Institution in Nigeria, and for that reason, points are not allocated to them as seen above. And the method above is not the only way points are allocated to your WAEC result, different Schools use different grading systems.

So, this way, if a student should have four (4) A’s and One (1) B3 in his or her five (5) core courses, then the O’ level result grade can be calculated as thus;

Where A is 10 points and B3 is 8 points

A in 3 core courses would be 3 x 10 = 30

B in 2 core courses would be 2 x 8 = 16

30 + 16 = 46

Therefore, the total WAEC aggregate for that student would be = 46

Now, if this same student should score let’s say, 270 in JAMB, bearing in mind that, your JAMB score is normally divided by 8, to constitute 50% of your admission aggregate.

The total aggregate for admission will then be:

270 / 8 = 33.75

33.75 (JAMB aggregate) + 46 (from WAEC grade) will be = 79.75

O’ level constituting about 20% for Some Universities, like the University of Lagos. For such schools, the students will have to sit for Post UTME (which will be 30%) and WAEC (50%).

For Schools that use O’ level (WAEC/NECO/NABTEB) as 20% to calculate students aggregate, Students with A in WAEC will have 4 points, while B, C, and D would be 3, 2, and 1 respectively.

From this calculation above, you will agree with me that, the better your WAEC result, the higher your chances of being admitted by the school you applied to.

NOTE: This is only applicable to schools that use a student’s O’ level result to calculate their aggregate score; universities like UNIBEN do not really consider your WAEC grade.


WAEC Marking Scheme for All subjects

WAEC marking scheme for all subjects determines the grade a student would be given, this WAEC marking scheme is similar to that for other O’ level exams like NECO and NABTEB.

The knowledge of the WAEC Marking scheme will allow you to be able to predict your grade in WAEC.

So, what is WAEC marking scheme, and how do they allocate grades to student.

How is WAEC marked and scored? (WAEC Marking scheme)

One pattern is used for calculating WAEC grades for all subjects (Mathematics, English Language, Biology, Commerce, Government, etc.

But you must first know the total marks allocated for the subjects (Because the total mark for subjects is not the same) before you can really do this calculation.

Total marks accumulated by the student (theory + objective), divided by total marks allocated to that subject, multiplied by one hundred.

Total marks accumulated by the student (theory + objective), divided by total marks allocated to that subject, multiplied by one hundred. The General formula for calculating your total WAEC grades in percentage is;

Total Marks Accrued by the Student (Theory + Objective), divided by Total Marks Allotted to that Subject, multiplied by 100

To summarize: the total score of the students or the total score for that subject multiplied by 100.

Whatever answer you get, would translate to your grade in WAEC, let’s take a look at this example below;


Here’s an example of how a WAEC subject is graded: Example of how a WAEC subject is marked:

If you were able to score 30 marks out of 50 in WAEC mathematics and get 75 marks in WAEC mathematics theory out of 100. Your percentage score will be calculated as thus…

30marks for objective + 75marks for theory, all divided by 150 (Since 150 is the total score for that subject, i.e. 50 for objective and 100 for theory) times (x) 100

This will then be 105/150 x 100 = 70%

Remember, from our table, 70% – 74% is B2, this means you would have B2 in WAEC, easy to calculate right?

You can try this with your other subjects to see what your grade in those would look like.


For subjects with Practical

For subjects with practical like biology, Physics, Chemistry, and others, the pattern for calculation is slightly different.

For Practical Subject the formulae would be;

Total Marks Accumulated by the Student (Theory + Objective + Practical), divided by the Total Marks Allocated To that Subject, all multiplied by a hundred.

Summarily: Students Total Score/Total Score for That subject x 100

This is all on the WAEC marking scheme.
