The Kwame Nkrumah University of Science and Technology, Ghana KNUST grading system was distinct from that of other Ghanaian institutions until it was reviewed in 2010. However, following the review, significant changes were made to align it with national standards.

While the rest of the universities used the Grade Point Average system, KNUST used the Cumulative Weighted Average. Since the implementation of the GPA system, the KNUST grading scale has been reviewed on a regular basis to reflect the country’s current academic situation.

Calculating CWA based on Class & CWA – Table 1

First Class70.00 and above
Second Class Upper60.00 – 69.99
Second Class Lower50.00 – 59.99
Pass40.00 – 49.99

Note: Anything less than 40.00 at the end of the academic period means the student will not be able to graduate. As a result, the student failed that particular degree program.

This can be interpreted in several ways. For example, if a student’s CWA is less than 40.00 at the end of the first year, the student is automatically withdrawn from school. However, if a student’s CWA falls below 40 during the second and third years, the student is repeated for that university level.

The steps for calculating the CWA are listed below. Consequently, you do not need to continue reading if you understand how to use these steps. However, if you require further guidance or clarification, please proceed with reading the following instructions.

You can follow the steps to perform your own basic CWA calculations and checks. Alternatively, if you prefer not to do so, continue reading to learn how the calculations for the template used in this article were made.

1: Multiply the percentage mark scored in each course by the course credit to obtain the Weighted Marks.

2: Add up all the Weighted Marks calculated up to the end of the semester in question to obtain the Cumulative Weighted Marks.

3: Sum up all the corresponding Course Credits to the end of the semester to obtain the Cumulative Credits.

4: To obtain your Cumulative Weighted Average (CWA) for the semester in question, divide the Cumulative Weighted Marks by the Cumulative Credits. This division is an essential step in determining your overall performance across all the courses taken during the semester.

In a semester, students can enroll in as few as three courses and as many as ten, 11, 12, and even 13 in some extreme cases. However, it is important to consider the workload and time management required for each course to ensure academic success.

A student taking three courses per semester and one taking 11 courses per semester, on the other hand, should all have cumulative credit marks between 16 and 21.

Assume you have the following courses scheduled for year one, semester one;

Student Name: Bremah Klu Vera.  Program: BSC. CONSTRUCTION TECH. & MGT

Course No.                 Credit Marks (Hrs)

BT 151                                   3

BT 153                                   2

BT 155                                   2

BT 157                                   2

BT 159                                   2

BT 161                                   2

BT 163                                   2

CTM 151                                3

CTM 157                                2

Cumulative Credit                  20

The student mentioned above has a total of 20 credits from nine registered courses. Additionally, the current CWA for a first-year student, without any examinations or recorded marks, is 100.00.

However, suppose that at the end of the semester, after combining the student’s examination scores, quizzes, assignments, and mid-semester examination scores, the following final results were obtained for each course enrolled.

To calculate the CWA for this student in the first-year first semester, it is necessary to multiply the credit marks for each course by the marks earned for that course. By doing so, you can accurately determine the weighted contribution of each course toward the overall CWA. This step allows for the determination of the weighted marks associated with each course and contributes to the overall calculation of the student’s CWA. As a result, BT 151 becomes 3 x 74, which equals 222.

These calculations have been completed, and as a result, they are shown in Table three. Furthermore, the table provides a comprehensive overview of the completed calculations.

Table 3: Sample calculations of Cumulative Weighted Marks

Course No.Credit Marks (Hrs) (A)Marks (100%) (B)Weighted Marks (A*B)
BT 151374222
BT 153271142
BT 155267134
BT 157289178
BT 159255110
BT 16124794
BT 163267134
CTM 151370210
CTM 15723468
                      Cumulative Weighted Marks1292

To get the CWA for the first year first semester of this student, the cumulative weighted marks are divided by the cumulative credits. This division allows for the calculation of the Cumulative Weighted Average (CWA), which provides a comprehensive assessment of the student’s academic performance across all courses taken in that semester. Hence, 1292/20 = 64.60

Thus, the CWA for Bremah Klu Vera for first year semester one is 64.60, second class upper.
