## Overview

88 out of 100 is a straightforward 88%. On the standard scale (which only uses A/B/C/D/F) this falls in the B band (80–89%), worth 3.0 GPA points. On the plus-minus scale, 87–89% earns a B+ at 3.3 GPA points — a meaningful 0.3-point boost. Whether your institution uses the standard or plus-minus scale can significantly affect your cumulative GPA.

## Method

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.
