Work out the score you need on the final exam

The job

It's week 14, your syllabus says the final is worth 30% of the course grade, and you want to know exactly what score keeps you at a B — or whether an A is still reachable.

Do the math

Enter your current grade (your average on the graded work so far), the final's weight as a percent, and your target course grade. The tool shows the needed score — plus, if you also enter an expected score, the projected course grade.

• Needed score over 100 means the target is no longer reachable — the tool says so rather than hiding it.
• A needed score of 0 or less means the target is already locked in; the exam can't hurt you.
• Current grade should be the running average only on work already graded, not including the final.

Worked example

Current 84, final worth 40%, target 80: you need (80 − 84×0.6) ÷ 0.4 = 74 on the final. An A target of 90 needs 99 — barely possible, which is the honest answer the tool prints.

Where it stops

Weighted-average math only — it can't model curved exams, dropped lowest scores, or a teacher who weights categories differently than the syllabus says. If your course uses points ('350 of 500 possible'), convert to percent first.
