Common NCES scale. Your class may use different cutoffs.

A displayed percentage can round up while the unrounded score remains below a cutoff.
One class may put an A at 90%; another may require 93%. Plus/minus letters and GPA points can differ too. A school-wide grade-point table does not automatically tell you a class's percentage cutoffs.
Each named scale applies to a specific setting: Emmanuel's scale is suggested, Ohio State's is law-only, and Mount Saint Vincent's is for professional and graduate study. Find their exact boundaries and official links on the grading-scale source page.
Custom cutoffs accept your own letter labels and minimum percentages. They do not guess corresponding GPA points.
With no rounding, the example 89.5% remains below a 90% cutoff. If your class rounds to the nearest whole percent first, it becomes 90% before assigning the letter.
A calculator displaying 90% does not prove the underlying score reached 90%. This tool applies the letter to the full value unless you select whole-percent rounding.
For an incomplete published scale, a score below its lowest published cutoff has no assumed letter. Use your instructor's rule for that range.
