I Have a 69 in the Class — What Do I Need on the Final?
Going into the final with a 69%: if the final is worth the typical 20%, you need more than a perfect score (an A isn't reachable). 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 69% and a heavily weighted final, your ceiling is 84.5% (50% weight) to 72.1% (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.
Percent and points are different animals
In a points-based course (600 points total), losing 12 points early costs the same as losing 12 late. In a weighted course, identical scores can move your grade differently depending on the category. Know which system you're in before doing mental math.
The A is gone — spend the time where it still moves
At 69% with a 20%-weighted final an A is out of reach, and that is genuinely useful information: it means these hours are worth more spent on a course where the letter can still move. Rank your courses by how much a grade can shift per hour before you open a book — the finals-week triage guide is a method for doing exactly that.

Common questions
How are letter grades calculated from percentages?
Most US schools map percentages to letters in 10-point bands: 90–100 is an A range, 80–89 a B range, 70–79 a C range, 60–69 a D range, and below 60 an F. Plus/minus splits each band roughly in thirds (e.g. 90–92 = A-, 93–96 = A, 97+ = A+). Individual schools and professors can and do vary the cutoffs.
What's a passing grade in college?
Usually a D (60%) technically passes, but 'passing' and 'counting' differ: many majors require a C or better in core courses, prerequisites often demand a C, and anything below a C can trigger a retake requirement. Financial aid typically also requires a 2.0 GPA overall. Check your program's rules, not just the university minimum.
