Enter your scores for each assignment category and the weight of your final exam to instantly see your current grade — and exactly what score you need on the final to hit any target. The question this calculator answers: given where you stand right now, is a particular final grade still mathematically achievable? For each common target (A, B, C, D) and your custom target, it shows the exact score needed on the final exam and whether that score is actually possible. The scenarios tab flips the question around: instead of asking what you need, it shows what final grade you'd end up with for every possible final exam score from 50% to 100%. This helps set realistic expectations before a high-stakes exam. Students use this before finals to decide where to focus study time — knowing you need a 94 to earn an A but only a 71 to secure a B changes how you prioritize across multiple exams.

Your course has homework (20%), quizzes (15%), two midterms (20% each), and a final (25%). You've scored 88, 81, 74, and 71 respectively. Your current grade before the final is 78%. To earn a B (83%), you need an 83% on the final — achievable. To earn an A (93%), you'd need 113% — not possible. Focus on the B and breathe easier.
How is a weighted grade calculated?
A weighted grade multiplies each score by its percentage weight, sums those products, then divides by the total weight used so far. For example, if homework is worth 20% and you scored 90%, it contributes 90 × 0.20 = 18 points to your grade. Summing all contributions and dividing by the fraction of the course completed gives your current percentage.
Why might my weights not add up to 100%?
If you haven't entered all categories yet — like a lab section or participation grade — the weights will sum to less than 100%. This is intentional: the calculator computes your current standing based only on completed work. Make sure all categories including the final exam weight sum to 100% to get the most accurate final exam target.
What does 'not possible' mean for a final exam score?
If the calculator shows 'not possible,' it means reaching that target grade requires more than 100% on the final exam — which isn't achievable under standard grading. This happens when the gap between your current standing and the target is larger than what the final exam can make up, given its weight. It's a signal to recalibrate your grade expectations for the course.
How do extra credit and dropped grades affect the calculation?
If your professor drops the lowest quiz score, manually exclude that score from the quiz average before entering it. For extra credit that adds bonus points to a category score (e.g., bringing an 88% to a 95%), just enter the adjusted score. Extra credit that adds points directly to the final grade is harder to model — estimate by increasing your target by the number of extra credit percentage points.
Should I focus more on the final or on earlier assignments?
It depends on the weight distribution. A final worth 40% of the grade deserves far more study time than one worth 15%. As a rule, allocate study time proportionally to assessment weight. If your course is still in progress, raising assignment scores now is higher leverage than solely banking on the final — every point gained before the final takes pressure off the exam.
