## Notes
- CGPA-to-percentage formulas are taken from each university's official ordinance/circular and cited on the page; conversions to a US 4.0 GPA are estimates, and the per-country variation is explained on the /scales/ pages.
- Sources are the institutions' own regulations or national qualifications/recognition bodies (never competitor aggregators).
