Simple weighted syllabus
A current non-final average and a 30% final fit the model directly, making the required exam score transparent.

FINAL EXAM OUTCOME SCENARIOS
Solve the required exam score and compare exact course-grade outcomes
The entered coursework grade is treated as the completed non-final portion. Each exam scenario is weighted into the course total without inventing curves or policy rules.

How to use
Compare exact final-exam outcomes against one documented target
- Enter the current grade for completed non-final coursework.
- Enter the final-exam weight exactly as stated in the syllabus.
- Enter the desired overall course grade.
- List realistic exam-score scenarios rather than vague best and worst labels.
- Review the required score before interpreting scenario outcomes.
- Confirm all drops, replacements, extra credit, caps, and rounding with the instructor or syllabus.
Grade fundamentals
Five concepts define the arithmetic
- Coursework grade
- Current percentage for the completed non-final portion.
- Exam weight
- Fraction of the final course grade assigned to the exam.
- Contribution
- Component percentage multiplied by its course weight.
- Target grade
- Desired numerical course percentage before letter-grade policy.
- Required score
- Exam percentage that makes the weighted total equal the target.
Calculation method
Weight completed coursework and solve the remaining exam contribution
The entered coursework percentage represents all work outside the final. Its weight is one minus the exam weight. The required exam score is the difference between target and coursework contribution divided by exam weight. Each listed exam score is then substituted into the same course-grade equation.
Policy boundary
The syllabus controls the grading model
Dropped assignments, category weights, extra credit, grade replacement, minimum-final rules, curves, rounding, incompletes, and letter-grade cutoffs can change the official result. Enter a coursework grade already consistent with those policies.
Feasibility boundary
A required score outside 0–100% is information, not an error
A value above 100% means the entered target cannot be reached under this simple weighted model without policy changes or extra credit. A value below 0% means the target is already secured mathematically, subject to minimum-exam rules.
Decision depth
Use scenarios for planning, not certainty
Scenario grades show arithmetic outcomes for entered exam scores. They do not predict exam difficulty, preparation effectiveness, grading reliability, curve decisions, or the instructor's official record.
Detailed calculation process
Weighted-grade equations and default substitution
Gcourse = Gwork(1 − wfinal) + Gfinal wfinalGfinal,required = [Gtarget − Gwork(1 − wfinal)] / wfinal
- Final weight 30% becomes w = 0.30; coursework weight is 0.70.
- Coursework contribution = 82×0.70 = 57.4 course points.
- Required exam contribution = 80−57.4 = 22.6 points.
- Required exam score = 22.6/0.30 = 75.333%.
- A 65% exam gives 57.4+19.5 = 76.9% overall.
- An 85% exam gives 57.4+25.5 = 82.9% overall; every listed scenario uses the same reconciliation.
The current result cards and scenario ledger provide the live reconciliation.
Result interpretation
Read the required score beside the scenario range
The required score answers a threshold question; the scenario table answers outcome questions. A narrow gap between realistic scenarios can support a precise plan, while a target beyond 100% requires policy or goal review rather than false decimal precision.
Decision analysis
Verify the gradebook before changing study priorities
Confirm missing items, ungraded work, category weighting, penalties, drops, and extra credit. A current grade shown by a learning-management system may include or exclude ungraded work differently from this model.
Evidence and data lineage
Retain the policy and current-grade snapshot
Keep course and section, syllabus version, assessment weights, current grade date, included assignments, missing and dropped items, extra credit, gradebook settings, target basis, scenario scores, instructor clarifications, calculation date, and exported unrounded results. Protect education records according to applicable privacy rules.
Limits and exclusions
What the scenario model does not establish
- No exam-score prediction, curve, scaling, rubric, or reliability estimate.
- No automatic dropped work, extra credit, category cap, replacement, penalty, or minimum-final rule.
- No official letter grade, transcript result, instructor decision, or appeal outcome.
- No study-time, learning, accessibility, accommodation, or wellbeing recommendation.
Key terminology

Worked decision cases
Gradebook policy can matter more than the arithmetic
Category drops and minimum-final rule
The current displayed grade may not match the completed coursework basis, and passing may require a separate minimum exam score.

Important note
This calculator provides arithmetic planning only. The syllabus, instructor, institution, and official gradebook govern weights, policies, accommodations, rounding, and final grades.
Frequently asked questions
What does current coursework grade mean?
It is the percentage for the entire completed non-final portion after applicable course policies.
Why must final weight be below 100%?
The model needs both a completed coursework portion and a remaining final-exam portion.
What if the required score is above 100%?
The target is mathematically unreachable under the entered simple weighting without additional policy effects.
What if it is below zero?
The entered target is already secured mathematically, unless a minimum-final or other policy applies.
Does the page round the official grade?
No. Official precision and rounding belong to course policy.
Can I enter letter grades?
No. Convert them only using the course's official numerical policy.
