Example Calculation
A student has scored 85% on homework (30% of grade), 78% on midterm (30% of grade), and wants to know what they need on the final (40% of grade) to get an A (90%).
Step-by-step calculation
- 1
Homework contribution: 85 × 0.30 = 25.5 points - 2
Midterm contribution: 78 × 0.30 = 23.4 points - 3
Current points earned: 25.5 + 23.4 = 48.9 points - 4
Points needed for 90%: 90.0 points - 5
Points needed from final: 90.0 - 48.9 = 41.1 points - 6
Required final score: 41.1 ÷ 0.40 = 102.75%
Result: The student would need 102.75% on the final to earn an A, which is not possible without extra credit. For a B (80%), they would need 77.75% on the final. For a B+ (87%), they would need 95.25% on the final.

Common Mistakes to Avoid
Not reading the syllabus carefully for grading policies like curving, rounding, or participation adjustments that change the math
Calculating grades for individual assignments separately instead of by weighted category
Forgetting that some professors cap grades at 100% while others allow scores above 100% with extra credit
Using the wrong grading scale — an 80% might be a B in one class and a C in another
Not factoring in attendance or participation grades that may be subjective or not yet finalized
Frequently Asked Questions
Pro Tips for Better Results
When calculating what you need on a final, remember that the maximum possible score may exceed 100% if the course offers extra credit
Use the calculator to identify the marginal value of each remaining assignment — which ones will move your grade the most if you do well or poorly
Track your assignment completion rate alongside your grades — missing assignments usually hurts more than low scores
Calculate your GPA separately for courses in your major, as many graduate programs care more about major GPA than cumulative GPA
Before each registration period, use the calculator to determine the minimum grades you need in current courses to maintain your target cumulative GPA
