Grading in education is the process of applying standardized measurements for varying levels of achievement in a course. Grades can be assigned as letters (usually A through F), as a range (for example, 1 to 6), as a percentage, or as a number out of a possible total (often out of 100).

In some countries, grades are averaged to create a grade point average (GPA). GPA is calculated by using the number of grade points a student earns in a given period of time.

GPAs are often calculated for high school, undergraduate, and graduate students, and can be used by potential employers or educational institutions to assess and compare applicants.

Kwame Nkrumah University of Science and Technology used the Weighted Averages Grading System, basically the Cumulative Weighted Average (CWA).

## How to Calculate KNUST GPA/CWA

The student’s scores in the assessment procedure, which is graded out of a possible 100, are used in the weighted averages (WA) system. Each course is weighted by credit hours according to the academic management’s established standards for each degree.

Each student’s CWA at the start of the semester is 100.00. The student is tested throughout the semester through quizzes, projects, exams, and other tasks.

At the conclusion of the entire course, including the degree class the student will receive, these are all used to determine the CWA of the student. Exams at KNUST are 70.00, with the remaining 30.00 going toward projects, assignments, and other things.

Following the conclusion of the semester, lecturers compute the student’s CWA using the formulas below:

The weighted marks are obtained by multiplying the percentage mark earned for the course credit.

To determine the cumulative weighted marks, add up all the weighted marks that were calculated to the end of the semester.

To get the cumulative credits, add all of the course credits up until the end of the semester.

For the specific semester, calculate the cumulative weighted average by dividing the cumulative weighted marks by the cumulative credits.
