The formula
Your final grade is a mix of your grade now and your exam score. The final's weight decides how much each one counts.
Example: you have 82%, you want 85%, and the final is worth 25% (0.25).
Your current grade counts for 75%: 82 × 0.75 = 61.5
You still need: 85 − 61.5 = 23.5
The final has to give you that: 23.5 ÷ 0.25 = 94%
Why the final's weight matters so much
Most finals are worth 15% to 40% of the grade. The more it's worth, the more one exam can move your grade, up or down.
Say you have 82%. With a final worth 20%, a perfect score only lifts you to 85.6%. With a final worth 40%, the same perfect score lifts you to 89.2%.
So if your final is worth a lot, it's your best chance to pull your grade up. If it's worth a little, your grade is mostly set already.
Frequently asked questions
How is the score I need worked out?
Needed = (target − current × (1 − weight)) ÷ weight, with the weight as a decimal. Example: current grade 82%, final worth 25%, target 85%. That's (85 − 82 × 0.75) ÷ 0.25 = 94. You need 94% on the final.
What if I need more than 100%?
Then that grade can't be reached with the final alone. Try a lower target, or ask your teacher about extra credit or missing work that could still count.
Where do I find how much my final is worth?
Check your syllabus or course outline. It usually lists each part of the grade, like "Final exam 30%". If it's not there, ask your teacher.
My class uses points, not percentages. Does this still work?
Yes. Divide the points you have by the points possible so far to get your current percentage. For the weight, divide the final's points by the total points in the course. Example: a 200-point final in a 1,000-point course is worth 20%.
What score do I need to pass?
Set your target to your passing grade. In most US classes that's 60% (a D) or 70% (a C). The result is the lowest score on the final that still gets you there.
How does letter grade mode work?
It uses the middle of your current letter grade's range, and the lowest score that counts as your target grade. For example, a current B counts as 85% and a target A- counts as 90%. For an exact answer, use percentages.
