Grading Scale for 25 Questions
Percent and letter grade for every score on a 25-question test.
On a 25-question test, each question is worth 4 points. This chart uses a standard plus/minus scale (A- at 90%, B- at 80%, C- at 70% and D- at 60%), so "an A" here means A- or better. Students need 23 right for an A, 20 for a B, 18 for a C and 15 for a D. They can miss 2 questions and still get an A, or 5 and still get a B.
- A23+ rightA- or better
- B20+ rightB- or better
- C18+ rightC- or better
- D15+ rightD- or better
