The night-before question, answered properly: with your current grade and the final's weight, here's the exact exam score that gets you to your target — and whether it's even possible.

The weighted-average behind it

Your course grade is a weighted blend: current work times its share, plus the final times its weight. Solving for the final's score gives one clean formula:

Required score
need = (target − current × (1−w)) ÷ w
78% now · final worth 30% · want 80%
(80 − 78×0.70) ÷ 0.30 = (80 − 54.6) ÷ 0.30 ≈ 84.7%

Reading the verdict

If the required score tops 100%, the target is mathematically gone — the ceiling row shows the best you can still finish with, which is worth knowing before you over-invest in one exam. If it's at or below zero, the target is already locked in. Between 90 and 100 means everything must go right; leave margin in your studying.

Watch the weight

The single most common error is entering the wrong weight — check the syllabus, and note some courses weight categories (homework, midterms, final) rather than one exam. Your "current grade" should be your standing across everything except the final. For the semester-wide picture, the GPA calculator is the companion tool.

Final grade FAQ

Subtract your current grade times its share from the target, then divide by the final's weight: at 78% with a 30% final, reaching 80% requires (80 − 78×0.7)÷0.3 ≈ 84.7%.

The target is out of reach — no exam score gets there. The calculator shows your ceiling (final grade at a perfect 100%) so you can aim for the best still-possible outcome.

Your weighted standing on everything except the final — most learning portals show it. If your course weights categories separately, use the syllabus weights to combine them first.

Not directly — replacement policies change the math per syllabus. Run it normally first; a replacement policy only ever helps beyond that baseline.
