Stony Brook grades on plus/minus points: an A is 4.00, an A− 3.67, a B+ 3.33 and so on down to a D at 1.00, with no D−, and an F at 0.00. Retake a course and only your highest grade counts in your GPA. A Q for academic dishonesty, an incomplete you don’t finish (I/F) and an NR that becomes N/F all count as an F, while P, NC, S, U and W stay out of your GPA.
Stony Brook’s points: A 4.00, A− 3.67, B+ 3.33, B 3.00 and so on.
The plus/minus cutoffs Wikipedia lists for US colleges: A+ from 97%, A 93, A- 90, B+ 87, B 83, B- 80 and so on down to D- at 60. It is not universal, so use your syllabus's cutoffs when they differ.Source: Wikipedia, “Academic grading in the United States”.

Each letter starts at its lowest percentage and runs up to the next letter.
Rounding and decimal places
Follow your syllabus. A displayed percentage can round up while the unrounded score stays below a cutoff.
Only changes how results are shown. Extra places appear when rounding would push a score over a letter cutoff.
A letter typed as a score counts as the lowest percentage for that letter on this scale. Use the original percentage when you have it.
Only scales that publish GPA points can convert a percentage. Check that your school uses these same points.

Raise my GPA: what would it take to reach a target?
These are future credits beyond the courses and earlier record entered above.
Pass/fail or a retake: what would change?
Whether a pass/fail course leaves the GPA and whether a retake replaces the old grade are your school’s rules; the table below shows Stony Brook’s.
One grade higher: which course moves your GPA most?
Each line raises one course by one grade on the grade points above and leaves the others as entered, so a course that carries more credit moves the GPA more. A course you haven’t finished can be marked “Planned” in its ⋯ menu: the GPA so far then leaves it out, and the projection counts it at the grade you chose. A grade already on your transcript changes only under your school’s retake or grade-change rules.

Set a course's group or term, or mark it planned, in its ⋯ menu. Groups are just your labels: they don’t apply AMCAS or other application-service GPA rules.

Grade points at Stony Brook
Stony Brook multiplies each course’s grade points by its credit hours, adds them up and divides by the hours that count. Enter your courses above with these points already set.
Stony Brook University letter grades and grade points
What W, pass/fail, incomplete, retakes and transfer credit do at Stony Brook
A course left out of the GPA adds no points and no hours. In the calculator, choose its code or “Not counted”; a code that counts as zero lowers the GPA like a failing grade.

Q
Academic dishonesty
Stays on your transcript and counts as an F, 0.00 points. After a single finding, you may get a letter grade from your instructor in its place by completing a non-credit seminar on academic dishonesty, unless the academic judiciary committee decides otherwise. Rule
I, I/F
Incomplete: more time granted for work that circumstances beyond your control kept you from finishing
Your instructor sets a deadline no later than November 1 for a spring or summer course and March 15 for a fall course, and can extend it to the last day of classes of the next semester. Work not finished by then becomes an I/F (or a U or NC, as appropriate), and an I/F counts as an F. You can’t finish an incomplete by auditing or taking the course again. Rule
NR, N/F
No Record: you’re on the final roster but the instructor has no record of you attending
An NR isn’t a grade in your GPA, but it’s converted on your transcript to N/F in a letter-graded course, and an N/F counts as an F. Not attending, or only telling the instructor, doesn’t withdraw you; if you never attended, you must petition for a retroactive withdrawal. Rule
P, NC (GPNC)
Graded/Pass/No Credit: you set a threshold letter grade by the end of the ninth week
Reach your threshold and your letter grade shows and counts; below it but above F you get a P, and an F becomes an NC. Neither P nor NC counts in your GPA. One course a term, once per course, never for a course you’re retaking, and P or NC doesn’t meet SBC, DEC, major or minor requirements. Engineering students can use it only for open electives, and P or NC courses don’t count toward the 12 credits for the Dean’s List. Rule
S, U
Satisfactory or Unsatisfactory, in courses graded only S/U
Not counted in your GPA, and such courses can’t be taken under GPNC. Rule
W
Withdrawal after the first ten days of classes
Shown on your transcript, not counted in your GPA. In fall and spring you can withdraw through the ninth week, and full-time students must keep at least 12 credits; after the ninth week you can only withdraw from all your courses. A W still counts as having taken the course when you retake it. Rule
R
Registered: the first semester of a year-long course (chiefly senior honors projects 495–496), or a grade delayed for remote coursework
Not counted in your GPA; the grade and credits for both semesters are recorded at the end of the second. Rule
Developmental courses (AIM 102, MAP 101, MAP 103)
Courses that prepare you for college-level work
Their grades count in your term GPA, the Dean’s List and academic standing, but not in your cumulative GPA. Rule
Repeated course
You took the same course again
Retake a course that isn’t marked “may be repeated” and only the highest grade of all your attempts counts in your GPA. Every graded attempt stays on your transcript, and the credits count once toward your total. You’ve taken a course once you stay past the add/drop deadline, whatever the grade, and a W counts as a grade. A third attempt needs a petition approved by the department (WAE 190, WAE 192, WAE 194, WRT 101 and WRT 102 are exempt). Departments may deny a retake if your cumulative GPA is below 2.0, you retake two or more courses in one semester, or you already earned a C or better. You can’t retake under GPNC. Courses that may be repeated, such as topics courses, are different: every grade counts and none replaces another. Taking a course that is mutually exclusive with one you’ve taken counts as a retake, and you risk losing its credits and grade. Rule
Transfer credit
Grades from another college
Grades from transferred courses aren’t shown on your transcript or counted in your Stony Brook GPA. Courses passed with a C or higher at accredited institutions are evaluated for credit, and a P or S may be accepted too. A SUNY or CUNY associate degree guarantees junior standing and 60 credits. After your 57th credit, 36 must be earned at Stony Brook, so at most 84 transfer credits (test credits included) count. Once enrolled, a course taken elsewhere needs a C or higher, at most 4 credits in winter and 18 in summer (9 in one session), and WRT 102 can’t be transferred. Rule

You also must not be on warning. Standing is reviewed after each fall and spring semester, on all your Stony Brook coursework that year, summer and winter included. Full rule
Below 2.0 cumulative after your first semester
First semester warning
You get an advising hold until you contact an advisor, and you can take at most 16 credits a semester. Full rule

Suspension
After first semester warning, a second semester below 2.0 with a cumulative below 2.0 also means suspension. You can petition for immediate reinstatement with a semester GPA of at least 2.0 (1.0 to 1.99 after first semester warning). Conditional reinstatement usually asks for a 2.5 semester GPA and 12 credits; missing its conditions means dismissal. Full rule
2.00 cumulative
The least you need to graduate
It covers all your academic work at Stony Brook. You also need at least 120 credits (128 for a Bachelor of Engineering), 39 upper-division credits, and 36 credits at Stony Brook after your 57th. Full rule
3.40 seniors, 3.30 juniors, 3.20 sophomores, 3.10 freshmen, for the semester
Dean’s List
You need at least 12 letter-graded credits that semester (S counts, P doesn’t) and no I, U, NR, NC, F, R or Q; part-time students need 6 letter-graded credits. Your class follows your earned credits: 85 or more senior, 57 to 84 junior, 24 to 56 sophomore. Full rule
3.85 / 3.70 / 3.50 cumulative
Summa cum laude / magna cum laude / cum laude
You need at least 55 credits at Stony Brook (not counting Challenge credit) and letter grades on at least 80 percent of your coursework. Full rule
To see how far you are from one of them, enter it under “Compare with a GPA line” in the calculator, or as your target in the target GPA planner.
A worked example
Under GPNC, a grade below your threshold becomes a P and stays out of your GPA. Say you earn an A− in a 4-credit course and a B in a 3-credit course, and a D in a 4-credit course you took under GPNC with a B− threshold: (3.67 × 4 + 3.00 × 3) ÷ 7 = 23.68 ÷ 7 = 3.38, where the same D taken for a letter grade would have given (3.67 × 4 + 3.00 × 3 + 1.00 × 4) ÷ 11 = 27.68 ÷ 11 = 2.52.
The calculator gives an estimate from the grades you enter. Your official GPA is the one on your Stony Brook academic record.
For any other college, the college GPA calculator starts on the common plus/minus 4.0 points and takes your school’s own. Cumulative GPA combines terms you already have, and the GPA guide answers what a GPA means.
