I Have a 76 in the Class — What Do I Need on the Final?

Going into the final with a 76%: if the final is worth the typical 20%, you need more than a perfect score (an A isn't reachable) and 96% for a B. Every common weight is below — or set your exact numbers in the calculator.

Reading this table

"Locked in" means even a zero on the final keeps that grade. "Not possible" means a perfect final still wouldn't get you there — with a 76% and a heavily weighted final, your ceiling is 88% (50% weight) to 78.4% (10% weight). The math: needed = (target − current × (1 − weight)) ÷ weight.

Worth knowing

Confirm the scale in your syllabus

The 90/80/70/60 letter cutoffs used here are the most common US scale, but plenty of courses curve, use plus/minus bands differently, or set an A at 94. The syllabus — not any calculator — is the contract that counts.

The final isn't all-or-nothing

Because finals are usually worth 20–40%, your semester of work is protecting you more than you think. Run the numbers: the score you actually need is often lower — sometimes dramatically lower — than the panic estimate.

Common questions

Is a 3.5 GPA good?

On the standard 4.0 scale, 3.5 sits between an A- and B+ average — comfortably above the typical US college average (around 3.1) and competitive for most graduate programs, internships and scholarships, though the most selective programs skew 3.7+. Trend matters too: an upward trajectory reads better than a flat one.

What's the difference between weighted and unweighted averages?

An unweighted average treats every score equally: add them up, divide by the count. A weighted average multiplies each category by its share of the grade first — homework 20%, midterms 40%, final 40% — which is how most courses actually work. If your syllabus lists category percentages, you need the weighted version.
