Grading Scale for 50 Questions
Percent and letter grade for every score on a 50-question test.
On a 50-question test, each question is worth 2 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 45 right for an A, 40 for a B, 35 for a C and 30 for a D. They can miss 5 questions and still get an A, or 10 and still get a B.
- A45+ rightA- or better
- B40+ rightB- or better
- C35+ rightC- or better
- D30+ rightD- or better
