How it's calculated
The calculation iterates through an ordered list of grade bands and returns the first band whose minimum and maximum percentage bounds (inclusive) contain the input score. The standard scale uses five bands (A, B, C, D, F) and assigns GPA points of 4.0, 3.0, 2.0, 1.0, and 0.0 respectively. The plus-minus scale uses thirteen bands (A+ through F) with GPA points drawn from the widely published US 4.0 system (source: back2college.com and calculator.net). Input is validated with Zod to reject values outside 0–100 before any lookup is performed.
