Purdue University-Main Campus in West Lafayette, Indiana uses a standard US 4.0 GPA scale with plus/minus modifiers for most letter grades. The scale ranges from 4.00 (A+ and A) down to 0.00 (E, which indicates failure). A distinctive feature of Purdue's system is that both A+ (98-100%) and A (93-97%) carry the same 4.00 GPA value, meaning students achieving the highest marks receive identical grade point contribution regardless of whether they score in the mid-90s or near-perfect. The university employs plus/minus distinctions for B and C grades, allowing for more granular assessment: a B+ earns 3.33, B earns 3.00, and B- earns 2.67, while C grades similarly range from C+ (2.33) to C (2.00). The D grade (60-69%) carries 1.00 grade points with no plus/minus variants, and any score below 60% results in an E (failure) worth 0.00.
