Hi HN — I built GPACalc to help students quickly calculate GPA/CGPA and convert GPA to percentage across different grading systems (4.0, 5.0, and 10.0).

It also lets you estimate cumulative results from current CGPA, completed credits, and expected semester grades. It’s free, no sign-up, and mobile-friendly.

I’d really value feedback on:

missing grading scales or country systems confusing parts of the UX features that would make this more useful for students/counselors
