Source: hand calculation in content.mdx: 100 × 43 ÷ 50 = 86%. 2. earned = 88, possible = 120 gives percent = 73.333333%, letter = C, missed = 32. Source: hand calculation in content.mdx: 100 × 88 ÷ 120 = 73.33%. 3. possible = 80, percent = 90% gives earned = 72, letter = A-, missed = 8. Source: hand calculation in content.mdx: 90 × 80 ÷ 100 = 72 points. 4. earned = 45, percent = 75% gives possible = 60. Source: hand calculation in content.mdx: 100 × 45 ÷ 75 = 60 points possible. 5. earned = 105, possible = 100 gives percent = 105%, letter = A, missed = 0, extra = 5. Source: hand calculation in content.mdx: extra credit, 100 × 105 ÷ 100 = 105%. ## FAQ ### How do I calculate a test score percentage? Divide the points you earned by the points possible and multiply by 100. 43 out of 50 is 43 ÷ 50 × 100 = 86%. ### How many points do I need for a 90%? Multiply the points possible by 90 and divide by 100. On an 80-point test, 90 × 80 ÷ 100 = 72 points. Enter the points possible and 90 as the score to get it. ### What is 88 out of 120 as a percentage? 88 ÷ 120 × 100 = 73.33%, a C on this page's scale. ### Can a score be above 100%? Yes, with extra credit. 105 points out of 100 is 105%. The page accepts scores up to 200%. It shows 0 points missed and the extra points as extra credit points. ### Which letter grade scale is used? The Tompkins Cortland Community College (SUNY) scale: A 93 and up, A- 90 to 92, B+ 87 to 89, B 83 to 86, B- 80 to 82, C+ 77 to 79, C 73 to 76, C- 70 to 72, D+ 67 to 69, D 63 to 66, D- 60 to 62, F 59 and below. Your teacher or school may use other cutoffs. ### What is the difference between this and the test grade calculator? The maths is the same percent. This page starts from the points you earned; the test grade calculator starts from the number of questions and the number wrong, as a teacher marks a test. ## Sources - Tompkins Cortland Community College (SUNY), Grading System: grading scale for converting between numerical and letter grades (A 93–100 through F 59 and below). https://www.tompkinscortland.edu/sites/default/files/documents/CollegeNow%20Grading%20Scale.pdf
