Uses the standard unweighted 4.0 scale (A = 4.0, B = 3.0 … F = 0.0); most schools count an A+ as 4.0. Weighted scales add 0.5 for honors and 1.0 for AP/IB courses — check your school's policy, since weighting varies.
How GPA Is Calculated
Each letter grade converts to grade points (A = 4.0, B = 3.0, and so on). Multiply each course's grade points by its credit hours to get quality points, then divide total quality points by total credits. A 4-credit B+ moves your GPA more than a 1-credit A — credits weight everything.
Formula
GPA = Σ (grade points × credits) ÷ Σ credits
Grade points (standard 4.0 scale):
A = 4.0 B+ = 3.3 C+ = 2.3 D+ = 1.3
A- = 3.7 B = 3.0 C = 2.0 D = 1.0
B- = 2.7 C- = 1.7 D- = 0.7 F = 0.0Frequently Asked Questions
How do I convert a percentage grade to a 4.0 GPA?
There's no universal mapping, but the common US convention is 93–100% = 4.0 (A), 90–92 = 3.7 (A-), 87–89 = 3.3 (B+), 83–86 = 3.0 (B), and so on down the scale. Your school's registrar mapping is the one that counts — some use 90+ for a flat A.
Do plus and minus grades change my GPA?
Yes, by 0.3 each step: an A- is 3.7 instead of 4.0, and a B+ is 3.3 instead of 3.0. The exception is A+, which most schools cap at 4.0 (a handful award 4.3). Over a 15-credit semester, turning two A-s into As moves your GPA by about 0.12.
What's the difference between weighted and unweighted GPA?
Unweighted GPA caps every class at 4.0. Weighted GPA adds bonus points for harder courses — typically +0.5 for honors and +1.0 for AP/IB — so a weighted scale runs to 5.0. Colleges often recalculate applicants' GPAs to their own formula, so the unweighted number still matters.
What GPA do I need to make the Dean's List?
Most universities set the Dean's List bar between 3.5 and 3.7 for the semester, usually with a minimum credit load (often 12 graded credits). Latin honors at graduation typically start around 3.5 cumulative (cum laude) and run to 3.9+ (summa cum laude), varying by school.
