What-If Scenarios
Here's the final course grade you'd get for each possible final exam score:

Standard 10-point grading scale (A: 90+, B: 80+, etc.).
How This Calculator Works
The formula:
Required Final = (Target − Current × (1 − Weight)) ÷ Weight
Where all values are decimals (so 30% = 0.30). Your final course grade = (Current × (1 − Weight)) + (Final × Weight). Solving for the Final gives the formula above. If the result is above 100, the target is mathematically unreachable — even with a perfect final. If it's below 0, you've already locked in your target regardless of how you do on the final.
Study Tips for the Final
✅ Strategy When You Need a High Score
- Focus on past exams and practice problems from the same professor
- Identify the 2-3 highest-weighted topic areas and master those first
- Use active recall (flashcards, practice tests) — not passive re-reading
- Form a study group to quiz each other and explain concepts
- Visit office hours to clarify the trickiest topics
📚 If the Target Is Out of Reach
- Aim for the highest grade you can still achieve (see scenarios above)
- Ask your professor about extra credit opportunities
- Make sure all other assignments are submitted — small points add up
- Consider whether the course might still count toward your major (some use the highest grade, others the most recent)
- Plan a stronger retake strategy if the course can be repeated
Frequently Asked Questions
How do I calculate what I need on the final?
The formula is: Required Final Score = (Target Grade − Current Grade × (1 − Final Weight)) ÷ Final Weight. For example, if you have an 85% current grade, want a 90% final, and the final is worth 30%, you need: (90 − 85 × 0.70) ÷ 0.30 = (90 − 59.5) ÷ 0.30 = 101.67%. Since 101.67% is above 100%, the goal is unreachable — even with a perfect final.
What if the required final score is over 100%?
If the required score exceeds 100%, the target grade is mathematically impossible to reach — even with a perfect final. This calculator flags that case so you can adjust your target to a realistic grade (e.g., B+ instead of A−). It also shows the highest grade you can actually achieve with a 100% on the final.
What if it's under 0%?
If the required score is below 0%, you've already locked in your target grade regardless of how you do on the final. You can technically score 0% and still hit your goal. This is a "rest easy" scenario.
How do I find my current grade?
Your current grade is your running grade in the course before the final, usually available in your course gradebook, LMS (Canvas, Blackboard, Brightspace, Moodle, Google Classroom), or student portal. Use the weighted average of all completed assignments weighted by their point values. If your LMS doesn't show it, you can compute it manually: (sum of (score × weight) for each assignment) ÷ (sum of weights).
How do I find the final exam weight?
Check your course syllabus. The final exam weight is usually listed as a percentage (e.g., "Final Exam: 25% of course grade"). If you can't find it, common weights are: 20% (many college courses), 30% (some college / most high school), or 40-50% (some AP / final-heavy courses). The final is sometimes split into "Final Exam" and "Final Project" — combine those weights.
Does this work for pass/fail courses?
Yes — set your target to the minimum passing grade (usually 60% or 70%) and your current grade to your running grade. The calculator will tell you the minimum final score needed to pass. Most pass/fail courses use 70% as the threshold.
