Find out precisely what you need to score on your final exam to hit the overall grade you want in a course. Enter your current grade in the class, the grade you are aiming for overall, and the percentage of your total mark that the final exam is worth. The calculator rearranges the weighted-average formula to solve for the exact score required on that final. It will also tell you honestly when the target is out of reach because even a perfect final cannot lift you high enough, or when you have already secured it and could score zero and still pass. This takes the anxiety and guesswork out of exam season and helps you set a realistic study goal. All math runs locally in your browser.
