Letter Grade Reference
A GPA — the grade that
opens every door.
An A is the standard top grade at most US colleges — 4.0 quality points, a 93–96% performance range, and the mark that satisfies Dean's List, honours, and graduate school requirements. Use the calculator below to see exactly how A grades move your cumulative GPA.

What it means
A vs A+ — the grade
that most colleges give
At most US four-year universities, A is the highest grade routinely awarded. Many institutions don't give A+ at all — or they award it so rarely it functions as honorary. When A is the ceiling, a 4.0 GPA by definition means a straight-A record.
The distinction between A and A+ matters far more in secondary school contexts, where class rank and valedictorian status hinge on fractions of a point. At the college level, the GPA arithmetic is usually identical. What changes is the narrative: a transcript heavy with A grades at a rigorous institution tells a compelling story for graduate school, fellowship applications, and academic hiring.
Honours and graduate school
What consistent A grades
unlock academically
Dean's List. Most US institutions require a semester GPA of 3.5 to 3.8 for Dean's List. A full semester of A grades (4.0 semester GPA) exceeds this at every institution that publishes the standard.
Latin Honors. Cum laude (usually 3.5+), magna cum laude (3.7+), and summa cum laude (3.9+) are cumulative GPA designations. Consistent A grades (4.0 per course) build toward summa, assuming no significant lower grades elsewhere in the record.
Graduate school. Most master's and doctoral programs look for 3.5+ GPA in the major. An A average (roughly 3.7–4.0) puts applicants in the competitive range for the vast majority of programs. Professional programs (medicine, law) typically want 3.7+ for competitive admissions.
Scholarships. Merit aid thresholds most commonly sit at 3.0, 3.25, or 3.5. A consistent A average comfortably exceeds all three. Renewal requirements (often 3.0–3.5 cumulative) are similarly well within reach when maintaining an A average.
Common questions
A GPA — FAQ
What is an A in GPA?
4.0 quality points per credit on both the 4.0 and 4.33 scale. It's the top grade at most US colleges, corresponding to approximately 93–96% performance.
Is A the same as A+ in GPA?
On the 4.0 scale, yes — both earn 4.0 points per credit. On the 4.33 scale, A earns 4.0 while A+ earns 4.33. Most US universities use the 4.0 scale, making A and A+ numerically identical.
What percentage is an A?
Most institutions define A as 93–96%, with A− at 90–92% and A+ at 97–100%. Some schools use 90–100% as an undivided A range without plus/minus modifiers.
Does an A qualify for Dean's List?
Yes. Dean's List requires 3.5–3.8 semester GPA at most schools. A semester of all A grades (4.0) exceeds every common threshold.
Is an A good enough for graduate school?
Yes for most programs. Top programs (medicine, law, elite PhD) look for 3.7+. An A average in relevant coursework is competitive for virtually all graduate admissions.
How does an A affect my cumulative GPA?
Each 3-credit A adds 12.0 quality points. The cumulative effect depends on your existing credit total — more credits = smaller swing per course. Use the calculator above for your exact numbers.
What GPA does all A grades produce?
Exactly 4.0 on the 4.0 scale. On the 4.33 scale, all-A grades also produce 4.0 — to exceed 4.0 on that scale requires A+ grades (4.33 pts each).
What is the difference between A and A−?
A earns 4.0 points; A− earns 3.7. In a 3-credit course, that's 12.0 vs 11.1 quality points — a difference of 0.9 QP per course. Over a full year (30 credits), the gap can be nearly 0.09 GPA points cumulative.
Can I graduate summa cum laude with an A average?
Possibly — summa cum laude typically requires 3.9–4.0 GPA. A consistent A average (4.0) qualifies, but any A− grades (3.7) will pull your cumulative GPA below 4.0. The threshold varies by institution.
How many credits of A do I need to raise my GPA to 4.0?
It depends on your current GPA and credit count. With a 3.8 over 60 credits, you'd need 60 more credits of A (4.0) to reach exactly 4.0 cumulative. GPA responds slowly at high credit counts — use the calculator to plan realistically.

GPA grading standards are maintained by individual institutions; aggregate academic data is reported to NCES IPEDS. Honours GPA thresholds and Dean's List criteria are set by each institution's academic regulations. The College Scorecard provides outcome data by institution. Common grading scale definitions are documented by institutional registrars — examples include the UC Davis Registrar and MIT Registrar.
