As a Science student, you may not have taken courses that are directly related to the courses in a B.A. Programme, but you can still calculate your overall grade percentage using the grades and credit hours for the courses you have taken. To calculate your grade percentage for a particular course, you can use the following formula:
Grade percentage = (Grade earned / Total possible grade) x 100%
For example, if you earned a grade of B in a 3-credit course with a total possible grade of 100%, your grade percentage would be:
Grade percentage = (80 / 100) x 100% = 80%
Once you have calculated the grade percentage for each course, you can calculate your overall grade percentage by taking the weighted average of your course grades, using the credit hours for each course as the weights. For example, if you earned a B in a 3-credit course and an A in a 4-credit course, your overall grade percentage would be:
Overall grade percentage = (3 x 80) + (4 x 90) / (3 + 4) = 85.71%
I hope this helps! If you have any further questions, feel free to ask.
