Letter grade uses the standard 90/80/70/60 thresholds (A/B/C/D), and points-to-next equals the next threshold percent of possible points minus points earned. ## Worked example Scoring 85 of 100 possible points is 85%, a B, with 5 points needed to reach 90% for an A. Scoring 45 of 50 is 90%, an A. ## Assumptions - Letter-grade thresholds assume the common 90/80/70/60 scale; your course may use different cutoffs. - Points-to-next only shows when the next letter threshold is reachable. - The tool does not weight assignments; enter total earned and total possible for the portion you want graded. ## Common questions ### How is a course grade calculated from points? Divide the points you earned by the total points possible and multiply by 100. Earning 85 of 100 points is 85%, which maps to a B on the standard 90/80/70/60 scale. ### How do I calculate what I need to get on an exam to raise my grade? For a points-based course, subtract the points you currently have from the points needed for the target letter grade. If you need 90% of 100 points (90 points) and have 85, you need 5 more points from the exam. ### What grade is 85 out of 100? 85 out of 100 is an 85% average, a B on the standard scale, and 5 points below the 90% cutoff for an A. ### What letter grade is 72 percent? 72% is a C on the standard 90/80/70/60 scale, and 8 percentage points below the 80% cutoff for a B. ### How do I calculate my grade with a final exam? Your final grade = current average × (1 − final weight/100) + final score × (final weight/100). For example, with an 82 average, a 20% final weight, and a 90 on the final, your course grade is 82 × 0.80 + 90 × 0.20 = 65.6 + 18 = 83.6, a B. Use the final-exam calculator to work backward and find the score you need. ### How much is a test worth in a grade? A test is usually worth 15–30% of a course grade; a single major test is often 20–25%, and a final exam is typically 10–30%. The weight is set by your instructor in the syllabus. Your final course grade is the weighted sum of each component (tests, quizzes, homework, participation) according to those weights. ### What grade is a 90 out of 100? 90 out of 100 is 90%, which is an A on the standard 90/80/70/60 letter scale (A = 90–100, B = 80–89, C = 70–79, D = 60–69, F = below 60). The exact cutoff for an A varies by instructor and school policy. ## Related tools - /final-exam-calculator/ - /gpa-calculator/ - /school-supply-budget-calculator/ ## Sources - [Calculation methodology and verification standard](/methodology/) --- *Local planning estimate.
