4.0 Letter-Grade Scale
Used by most US universities and many international institutions. Each letter grade maps to a fixed grade-point value, with plus and minus subdivisions for finer granularity. Some schools omit pluses/minuses, and a handful use 4.3 or 4.5 as the maximum — all stored per university.
