Japan Standard S/A/B/C 4.0 Scale

Reference model only. UTokyo course catalogues show faculty/course-specific grading patterns; the S/A/B/C/F mapping below is illustrative and must not be treated as a universal UTokyo conversion.

Conversion category: Mathematical estimate / normalization

Conversion shown: GPA × 25 (illustrative only; not universal)

Conversion note: UTokyo does not have one universal GPA mapping across every faculty/programme. The displayed point scale is a reference model only.

Questions students ask

Is S=4, A=3 or A=4, B=3 correct?

Both patterns exist in Japan. Some universities treat S as a distinct top grade worth 4.0 with A at 3.0; others map A to 4.0 and use S purely as an honour marker. Check your faculty handbook (履修要項) before converting.
