Score needed on the final for 90%110%

How to calculate the grade you need on your final

Score needed = (grade you want − current grade × (1 − final weight)) ÷ final weight, with the weight as a decimal.

For example, with an 85% in the class, a final worth 20% and a goal of 90%: (90 − 85 × 0.8) ÷ 0.2 = (90 − 68) ÷ 0.2 = 110%. An A isn't possible without extra credit, but a B needs only (80 − 68) ÷ 0.2 = 60%.

How your final changes your grade

Grade after the final = current grade × (1 − final weight) + final exam score × final weight.

The bigger the final's weight, the more it can move your grade, in either direction. With a final worth 20%, every 10 points on the exam moves your course grade by 2 points.

Don't know your current grade?

Use the categories tab. Enter each category from your syllabus (homework, quizzes, tests…) with its weight and your average, and the calculator works out your grade so far. Then tap the button to see what you need on the final.

Final Grade Calculator FAQs

What do I need on my final to pass?

Set the grade you want to your class's passing grade, often 60% or 70%, and the calculator shows the score you need. The table also lists the score needed for an A, B, C and D.

What if I need more than 100% on the final?

Then that grade isn't reachable with the final alone. Ask your teacher about extra credit or other assignments still to be graded, or aim for the next grade down.

How do I find my final exam weight?

It's usually in your syllabus or gradebook, often between 10% and 30%. If your final is in a 'Tests' category instead, use the categories tab.

Does this work for points-based classes?

Yes, if you turn points into percentages. Your current grade is the points earned divided by points possible so far, and the final's weight is its points divided by the total points in the course.

Is this calculator accurate?

The math is exact for weighted grades. Your teacher may round, drop the lowest scores or use different letter-grade cut-offs, so check your syllabus.
