I Have a 63 in the Class — What Do I Need on the Final?
Going into the final with a 63%: 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 63% and a heavily weighted final, your ceiling is 81.5% (50% weight) to 66.7% (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 63% 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.
We keep free study resources for 13 subjects — what specifically loses students marks in that course, free courses and open textbooks worth the time, and separate plans for whether you have a week or one night. Algebra, Precalculus, Calculus, Statistics, General Chemistry, or all 13 subjects.
Common questions
What GPA do I need for the Dean's List?
Most schools set Dean's List between 3.5 and 3.7 for the semester, with a minimum credit load (often 12+ graded credits). It's a semester GPA, not cumulative — one strong term can make the list even in a rebuilding year. Your school's exact cutoff will be published by the registrar.
Why does my school's GPA differ from this one?
Schools differ on three things: whether A+ counts as 4.3 or 4.0, whether plus/minus grades are used at all, and whether honors/AP courses are weighted above 4.0. This calculator uses the most common unweighted convention (A+ = 4.0, minus/plus in 0.3 steps). Your registrar's number is the official one.
