Frequently asked questions
How do I calculate what I need on my final?
Needed score = (target grade − current grade × (1 − final weight)) ÷ final weight. With a 88% current grade, a 20% final and a 90% target: (90 − 88×0.80) ÷ 0.20 = 98%. The calculator does this for any numbers.
Can my final exam bring my grade up a whole letter?
Only if it carries enough weight. A final worth 20% can move your course grade at most 20 points in either direction, and only if you score 0 or 100. The “possible range” line above shows exactly how far your grade can move.
What if the calculator says I need more than 100%?
Your target is mathematically out of reach with this final alone. Check whether extra credit, dropped quizzes or rounding policies apply, or aim for the highest reachable grade, which the calculator shows.
Does this work when the final replaces my lowest test score?
Not directly, replacement policies change the math. Recompute your current grade as if the lowest test were removed, adjust the category weights, then use the calculator with those numbers.
What grade do I need on the final to pass with a 60?
Set the target to 60 and enter your numbers. For example with a 55 current grade and a 25% final you would need (60 − 55×0.75) ÷ 0.25 = 75%.
Method: course grade = current × (1 − w) + final × w, where w is the final’s weight. Solve for the final score. Assumes a single final exam and no replacement/extra-credit policies.
