How your result is calculated
SLIIT's regulation adds conditions to this average; they are listed in the rules below.
- The pass grade is C.
- Semester GPA = Σ (credits × grade point) ÷ Σ credits for the courses followed in the semester.
- WGPA: the GPA for each year (Σ credits × grade point ÷ Σ credits for that year) is multiplied by the year's weighting factor and the results are added. Weights — Faculty of Computing: year 1 0%, year 2 20%, year 3 30%, year 4 50%; Faculty of Engineering and School of Business: 10%, 20%, 30%, 40%. Weights may vary with programme requirements.
- The WGPA is used to decide the award of classes for students from the 2017 intake onwards.
