Scale guide: Standard 4.0 is the most common in China; the PKU formula (4 − 3(100−x)²/1600) is smoother and widely accepted for US applications; WES is used by many US/Canada credential evaluations and is relatively generous for scores 85+. Reference lines: 3.0+ is generally safe for graduate school; 3.5+ is competitive for top programs; below 2.0 risks academic probation at most schools.
