🧮 How GPA is Calculated (Reg 2021)
The formula is based on credit weightage. High-credit subjects (like Math or Core Theory) impact your GPA more than labs.
- Formula:
GPA = Σ (Credit × Grade Point) ÷ Σ Total Credits - Example: If you get an ‘A+’ (9 points) in a 4-credit subject, you earn 36 credit points. If you get ‘O’ (10 points) in a 2-credit lab, you earn 20 credit points.
