Each score is multiplied by its weight, summed, and divided by total weight: 80 at weight 70 plus 90 at weight 30 is (5600 + 2700) ÷ 100 = 83.00. Normalisation by the weight total means 70/30, 7/3, and 0.7/0.3 all give the same answer — only the proportions matter, never the scale they are written in.
Enter each component's score with the exact weight from the syllabus (percent or points, but consistent). Then use it backwards: plug trial scores for the pending exam to find the marks that lift the average to your target — the fastest way to see whether an A is still mathematically alive.
It does not curve, drop lowest scores, or apply grade boundaries — it averages the scores and weights you enter, with institutional adjustments left to the examiner.
Averages only — no curves, drops, or boundaries.
No. The average divides by the total of the weights, so any consistent set of weights works.
Indirectly — enter your known scores and weights, then try target scores for the remaining component to see the effect.
Add it as another score-weight pair on top: extra credit raises the total earned without raising the total possible, which this normalising average handles naturally.
