The number students actually need
Almost every grade question is really the same question: "what do I need on the final?" A simple average lies about this — it pretends the 10% quiz and the 40% final matter equally, and they do not. Weighting fixes that, and the final-exam solver goes one step further: given where you stand and what the final is worth, it names the score that gets you your target — or tells you honestly when the target is out of reach, so you can adjust your aim (or your study plan) while there is still time.
