Get the weighting from the course syllabus
Find the final's percentage of the overall course grade. Confirm that your current average represents all of the other work and that no assignment is still missing from it. When categories have different weights, calculate their weighted contribution or use the course's correctly weighted average. Check whether there is a separate minimum exam mark.
Solve for the final score you need
Multiply the current average by the completed-work share. Subtract that contribution from the target course grade and divide by the final's weight as a decimal. Keep all grades on the same scale. If the result has decimals, check how the institution rounds and whether the exam can award the exact mark.
Turn the number into a practice target
Compare the required result with a timed sample marked under the course's rules. Use the gap to choose your next practice. If the calculation gives a value above 100%, check the weights and course policies before setting a revised target. For results at or below zero, still check any requirement to sit or pass the exam.
Worked example
Your current weighted average is 78%, the final is worth 40%, and the target is 80%. Completed work contributes 78 × 0.60 = 46.8 course points. You need another 33.2 points from the exam, so divide by 0.40. The required final score is 83%, assuming the course has no extra rules.
Before you finish
- Check for ungraded work and separately weighted categories.
- Use the published rounding and minimum-mark rules.
- Compare your target with a fresh timed attempt.
