Run the number before finals week
The needed score is a study-allocation tool. If you need 99% in one course and 62% in another, your hours should follow that gap. Students who compute the number early consistently out-perform students who study every subject equally, because finals are weighted bets — the formula tells you the odds.
When the number is impossible
A needed score above 100% isn't a dead end — it's a signal to change the lever: ask about extra credit before the exam, check whether the course is curved (curves apply after this math), or renegotiate the target grade. A realistic B secured beats an A chased into burnout across three other courses.
FAQ
What if the needed score is over 100%?
The target grade is unreachable on points alone. Your options are extra credit, a class curve, or adjusting the target — the calculator shows your best possible finish so you can pick a realistic one.
What if the needed score is negative?
You've already locked the target: even scoring zero on the final keeps you above it. The calculator clamps the display at 0% and shows your floor.
Does this work if the final replaces my lowest test?
Not directly — replacement policies change your current average too. Compute your current average with the lowest test removed, then use that as the current grade input.
