The 90-80-70-60 scale as one state writes it into law: Florida Statutes, section 1003.437, "Middle and high school grading system" (The 2026 Florida Statutes, read on 6 October 2026 at leg.state.fl.us). It gives each letter a range of whole percents and a grade point value. A school, a district or a teacher may use another scale, and theirs decides the grade.

How it works

Sixteen questions are worth exactly 6.25 points each, so no percent in the table is rounded: 12 × 6.25 = 75. Every 4 right answers add a quarter. The table below lists all 17 scores.

Working out a score out of 16 by hand

Multiply the score by 6.25. Or build it from halves: 8 right is 50%, 4 is 25%, 2 is 12.5% and 1 is 6.25%. Since 12 is 8 + 4, the percent is 50 + 25 = 75. For 13 right add one more question's 6.25 to reach 81.25%, a B.
