Assumptions and limitations
Grade systems vary across schools and universities. Weights are relative; this is not an automatic institution-specific GPA/CGPA converter. Attendance assumes every future class is attended.
How to use this tool
Choose a calculation mode, enter valid inputs, and read the result. Each mode is linked from the directory. Calculations happen on your device, with no required account or paid API. Verify consequential financial or technical decisions independently.

Additional calculation notes
Population standard deviation divides by the number of observations, not Nā1. Greatest common divisor and least common multiple accept safe whole numbers only.
