Most Tanzanian certificate, diploma and degree programmes compute GPA on a 5.0-point scale where course points are weighted by credit units. This calculator uses that credit-weighted method: GPA = Σ(points × credits) ÷ Σ(credits).
Configurable example GPA scale. Institutions define their own credit weights and grade points per their regulator's rules.
Indicative calculation using this example scheme — your institution's official grading takes precedence.
Example: a course scored 85% with 3 credit units earns grade A (5 points) → 15 weighted points. A 70% course with 2 credits earns B (4 points) → 8 weighted points. GPA = (15 + 8) ÷ 5 credits = 4.6.
No. The 5.0 credit-weighted scale is a widely used example. Institutions and regulators publish their own grade-point tables — always confirm with your institution's regulations before relying on a GPA for official purposes.
A 4-credit course affects your GPA twice as much as a 2-credit course, because it represents twice the learning workload. A plain average would treat them equally.
