Exam Score Target Planner
Calculate exam score needed to reach target grade with feasibility analysis. Enter values for instant results with step-by-step formulas.
Formula
Needed Score = (Target × 100 - Current × CompletedWeight) / ExamWeight
Rearranges the weighted average formula to solve for exam score. If result exceeds 100%, target is impossible. Always verify weights sum to 100%.
Worked Examples
Example 1: Reaching an A-
Problem:Current: 87% on 70% of grade. Need 90% overall. Final exam is 30% of grade.
Solution:Given:\nCurrent = 87%, Target = 90%\nCompleted weight = 70%\nExam weight = 30%\n\nNeeded = (Target×100 - Current×Completed) / Exam\nNeeded = (90×100 - 87×70) / 30\nNeeded = (9000 - 6090) / 30\nNeeded = 2910 / 30 = 97%\n\nDifficulty: Very Challenging\nPossible but requires excellent performance.\n\nAlternative targets:\nFor 89% overall: need 93.7%\nFor 88% overall: need 90.3%\nFor 87% (maintain): need 87%
Result:Need 97% on final | Challenging but possible | Consider 88-89% target
Example 2: Passing the Class
Problem:Current: 62% on 60% of grade. Need 70% to pass. Final is 40%.
Solution:Given:\nCurrent = 62%, Target = 70% (pass)\nCompleted = 60%, Exam = 40%\n\nNeeded = (70×100 - 62×60) / 40\nNeeded = (7000 - 3720) / 40\nNeeded = 3280 / 40 = 82%\n\nThis is achievable!\n\nIf perform at current level (62%):\nFinal grade = (62×60 + 62×40)/100 = 62% (fail)\n\nNeed 20-point improvement on exam vs current average.\n\nStudy strategy: Focus on high-weight topics, use practice exams, office hours.
Result:Need 82% to pass | Achievable | Requires 20-point improvement
Example 3: Impossible Target
Problem:Current: 75% on 80% of grade. Want 90% overall. Final is 20%.
Solution:Given:\nCurrent = 75%, Target = 90%\nCompleted = 80%, Exam = 20%\n\nNeeded = (90×100 - 75×80) / 20\nNeeded = (9000 - 6000) / 20\nNeeded = 3000 / 20 = 150%\n\nIMPOSSIBLE - Cannot score over 100%\n\nMaximum possible grade:\nWith 100% on final: (75×80 + 100×20)/100 = 80%\n\nRealistic targets:\n80% overall: need 100% (very hard)\n78% overall: need 90%\n76% overall: need 80%\n\nFocus on maximizing within realistic bounds.
Result:90% impossible | Max possible: 80% | Target 78% (need 90% on final)
Frequently Asked Questions
What if the needed score is over 100%?
If needed score exceeds 100%, the target is mathematically impossible. Options: lower target, seek extra credit, or check if exam weight/current grade are accurate. Focus on maximizing exam score instead.
How do exam weights work?
Weights represent percentage of final grade. If final exam is 30% and coursework is 70%, multiply each by their weight and sum. Final Grade = (Coursework × 0.70) + (Exam × 0.30).
