How do students usually calculate their GWA accurately?

Hello everyone,

I’m a student and recently I needed to calculate my General Weighted Average (GWA) for academic evaluation and possible scholarship applications. Doing it manually became confusing because each subject has different units, and a small mistake can change the final result.

I started looking for an easier and more reliable way and found an online GWA calculator for students that allows you to enter grades and corresponding units, then instantly calculates the final average. It made the whole process much clearer and helped me double-check my results.

I’m curious how do you usually calculate your GWA or academic averages?
Do you prefer manual calculation, spreadsheets, or online tools?
