Find the average score you need on everything left in the course to hit your target overall grade.
Find the score you need on your final exam to reach a target grade in the course.
A weighted grade is a course grade where different assignments count for different amounts toward the final result. Instead of a simple average of every score, each score is multiplied by its weight — usually a percentage — before being combined. A final exam worth 40% affects your grade far more than a homework worth 5%, even if both scores are identical.
Multiply each assignment's score by its weight, add the results together, then divide by the total weight.
If part of your grade is already locked in, you can work backward to find what average you need on everything left to hit a target.
This is a special case of the formula above, where the "remaining work" is just the final exam.
It means the target grade is mathematically out of reach — even a perfect 100% on everything remaining wouldn't get you there, given the weights involved. The only ways to change that outcome are lowering the target grade, improving scores already earned (if regrades are possible), or the remaining work carrying more weight than currently assumed.
| Letter Grade | GPA | Percentage |
|---|---|---|
| A+ | 4.3 | 97–100% |
| A | 4.0 | 93–96% |
| A- | 3.7 | 90–92% |
| B+ | 3.3 | 87–89% |
| B | 3.0 | 83–86% |
| B- | 2.7 | 80–82% |
| C+ | 2.3 | 77–79% |
| C | 2.0 | 73–76% |
| C- | 1.7 | 70–72% |
| D+ | 1.3 | 67–69% |
| D | 1.0 | 63–66% |
| D- | 0.7 | 60–62% |
| F | 0.0 | 0–59% |
Grading scales vary by school and instructor — check your syllabus for the exact scale your course uses.
Multiply each assignment's score by its weight, add those products together, then divide by the total weight. For example, a 90 worth 5%, an 85 worth 20%, and an 88 worth 20% gives (90x5 + 85x20 + 88x20) / (5+20+20) = 86.9%.
Multiply your target overall grade by 100, subtract your current grade multiplied by the weight already completed, then divide by the weight still remaining. This tells you the average score you need across everything left in the course to reach your goal.
Multiply your desired final grade by 100, subtract your current grade multiplied by the weight of everything except the final, then divide by the final exam's weight. For example, with an 88 current grade, an 85 target, and a final worth 40%, you would need 80.5% on the final.
A required score above 100% means your target grade is mathematically impossible to reach even with a perfect score on the remaining work, given the current grade and weights entered. Lowering the target grade or increasing what's left to complete are the only ways to make it achievable.
The grade percentage is the score earned on a specific assignment, out of 100. The weight is how much that assignment counts toward the final course grade, usually also expressed as a percentage. A homework worth 5% weight barely moves the final grade even with a perfect score, while an exam worth 40% weight has a much bigger impact.
