How do I calculate my grade percentage?

To calculate your grade percentage, divide your score by the total possible points and multiply by 100. Formula: (Score / Total Points) × 100. Example: 85 out of 100 = 85%. If you scored 43 out of 50 on a test: (43 / 50) × 100 = 86%. Use the Test Grade tab above to calculate instantly.

What do I need on my final exam to pass the class?

To find the score you need on your final exam: (1) Determine your current grade percentage. (2) Know the weight of your current grade (e.g., 70%) and the final exam weight (e.g., 30%). (3) Use the formula: Needed Final Score = (Desired Grade - (Current Grade × Current Weight %)) / Final Weight %. Example: want 80%, have 75% (70% weight), final is 30% weight: Needed = (80 - 75×0.70) / 0.30 = (80 - 52.5) / 0.30 = 91.7%.

How do I calculate a weighted grade average?

To calculate a weighted grade average: multiply each category grade by its weight, sum those products, then divide by the total weight. Formula: Weighted Average = Σ(Grade × Weight) / Σ(Weight). Example: Homework 85% (weight 20%), Midterm 78% (weight 30%), Final 92% (weight 50%). Weighted average = (85×20 + 78×30 + 92×50) / 100 = (1700 + 2340 + 4600) / 100 = 86.4%.

What percentage is an A, B, C, D, or F?

Standard US letter grade scale: A+ = 97-100%, A = 93-96%, A- = 90-92%, B+ = 87-89%, B = 83-86%, B- = 80-82%, C+ = 77-79%, C = 73-76%, C- = 70-72%, D+ = 67-69%, D = 63-66%, D- = 60-62%, F = below 60%. Note: some schools use different cutoffs, so check your syllabus for your instructor's scale.

How do I calculate my final grade with multiple assignments?

To calculate your final grade with multiple assignments: add all your earned points together, add all possible points together, then divide. Example: Test 1: 82/100, Test 2: 91/100, Quiz: 18/20, Homework: 48/50. Total: 239/270 = 88.5% (B+). This is a simple average; if categories have different weights, use the weighted average method instead.

Can I still pass the class?

Use the "Grade Needed" tab to check. Enter your current grade, the weight of your current work, your desired final grade, and the final exam weight. If the required score exceeds 100%, passing your desired grade is mathematically impossible. If it shows 105% you need on your final, consider whether extra credit options exist or if adjusting your target grade to a lower threshold (like 70% vs 90%) is realistic.

What is the difference between weighted and unweighted grades?

Unweighted grades treat all assignments equally regardless of point value — a 10-point quiz counts the same as a 100-point test. Weighted grades assign different importance to different categories (e.g., finals = 40%, homework = 20%). Most college courses use weighted grades by category. If all your assignments have the same point value, your simple average and weighted average will be identical.

To calculate a test grade: divide score by total points and multiply by 100. 85/100 = 85% (B). Letter grade scale: A = 90-100%, B = 80-89%, C = 70-79%, D = 60-69%, F = below 60%. To find score needed on a final: (Desired Grade - Current Grade × Current Weight) / Final Weight = Required Final Score. For weighted averages, multiply each category grade by its weight percentage and divide by total weight.
