What a 3.8 GPA means
A 3.8 sits between letters; the nearest is an A- average on the common 4.0 scale, which puts it at about 92% (an A- runs 90 to 92 percent where schools use pluses and minuses). That is well above the US average and over every common scholarship line, 0.69 points above the 3.11 national average for the class of 2019.
| Scale | 3.8 equals |
|---|---|
| Nearest letter grade | A- |
| Percentage (10 point, plus and minus) | 90 to 92% |
| Plain 10 point scale | A, 90 to 100% |
| 5.0 weighted scale (all AP or IB classes) | 4.8 |
The 5.0 row is the same grades with every class AP, IB or dual enrollment, which adds 1.0 to each grade except an F (Honors adds 0.5). Source: Rockingham County Schools (NC), state ten point grade scale and course weighting, checked Oct 17, 2026. Your school's weighting may differ.

Grades that make a 3.8 GPA
With six classes of equal credits, 8 different mixes of letter grades round to a 3.8; the table shows the 4 simplest. The simplest is A, A, A-, A-, A-, A- (3.80); A, A, A, A, A, B- gets there too (3.78). A GPA hides which grades made it, so two students with the same 3.8 can have very different transcripts.
| Grades in six equal credit classes | GPA |
|---|---|
| A, A, A-, A-, A-, A- | 3.80 |
| A, A, A, A, A, B- | 3.78 |
| A, A, A, A, B+, B+ | 3.77 |
| A, A, A, A, A, B | 3.83 |
Common 4.0 scale, unweighted; each average rounds to 3.8. Classes with more credits count for more.
How to raise a 3.8 GPA
How fast a 3.8 moves depends on the credits behind it. The table shows three starting points with a 15 hour term ahead: the GPA after a term of straight As and the term GPA that reaches 3.9, a typical summa cum laude line. When one term is not enough, the cell says how many credit hours of straight As get there.
| Starting point | After straight As | Term GPA for a 3.9 |
|---|---|---|
| After one semester (15 hours) | 3.90 | 4.00 |
| After one year (30 hours) | 3.87 | over 4.0 (30 hours of As) |
| After two years (60 hours) | 3.84 | over 4.0 (60 hours of As) |
Unweighted 4.0 scale, credits weighted. "Over 4.0": more than one term, with the credits of straight As that reach it. "Not reachable": a 4.0 cumulative, which needs an A in every class from the start.
One class counts too. With 30 credits behind a 3.8, a single 3 credit A lifts it to 3.82, a B drops it to 3.73 and an F drops it to 3.45.
To add each class with its own grade and credits, use the cumulative GPA calculator; to see how many terms a higher GPA takes from your own credits, use the raise GPA calculator.
If your school ranks students, it usually uses GPA, often weighted. To see your place as a percentile or decile, use the class rank calculator.
Can you get above a 4.0? Not on the unweighted scale, and from a 3.8 a 4.0 cumulative stays out of reach, because it needs an A in every class from the start. A weighted GPA can pass it: the same 3.8 with every class AP or IB is 4.8. The 4.0 GPA page shows what keeping a perfect record takes.
How this calculator works
A 3.8 sits between an A- (3.7) and an A (4.0) on the common 4.0 scale, 0.1 and 0.2 points away, so the nearest letter is A-. The percentage is placed inside the A- band (90 to 92) by how far the GPA sits from the points of an A-. Your school may count an A+ as 4.33, drop pluses and minuses, or weight honors and AP classes, so this is the common reading, not a rule.
The planner at the top starts with a 3.8 over 30 credits and a term of As over 15: (3.8 x 30 + 4.0 x 15) / 45 = 3.87. Change the credits or the average you expect and the new cumulative GPA updates; the more credits are behind a GPA, the less one term moves it.
Worked example
You have a 3.8 GPA over 30 credit hours and you are taking 15 hours next term. What does a term of straight As do, and what term GPA reaches a 3.9?
- Quality points so far: 3.8 x 30 = 114.
- A term of As adds 4.0 x 15 = 60 points: (114 + 60) / 45 = 3.87.
- For a 3.9: (3.9 x 45 minus 114) / 15 = 4.10, more than a 4.0 term allows, so it takes more than one term (30 hours of straight As).
Straight As lift a 3.8 to 3.87; a 3.9 takes 30 hours of straight As.
Questions and answers
Is a 3.8 GPA good?
A 3.8 is an A- average, well above the US average and over every common scholarship line. It sits 0.69 points above the 3.11 national average for the class of 2019. The next line worth aiming for is 3.9, a typical summa cum laude line.
Is a 3.8 GPA good in college?
Yes. In college a 3.8 meets the 3.5 that many dean's lists and cum laude cutoffs use, and it clears the 3.0 most scholarships and internships ask for. The next line is 3.9, a typical summa cum laude line, 0.10 points up.
What letter grade is a 3.8 GPA?
3.8 GPA letter grade: about an A-. The nearest letter on the common 4.0 scale is A- (3.7 points), 0.1 below a 3.8, so it reads as an A- average with a few higher grades mixed in. On the 10 point scale with pluses and minuses an A- covers 90 to 92 percent.
What is a 3.8 GPA in percentage?
About 92% on the 10 point scale with pluses and minuses, where an A- runs from 90 to 92. There is no exact conversion back, because a GPA only keeps the letter: a 90% and a 92% are both an A- and both count 3.7. The converter on the GPA scale page uses your own school's scale.
How do I raise a 3.8 GPA to a 3.9?
It depends on how many credits the 3.8 already covers. After one semester (15 hours): a 4.00 term GPA over 15 hours; After one year (30 hours): more than one term: 30 hours of straight As; After two years (60 hours): more than one term: 60 hours of straight As. The planner above starts at 30 credits; change them to match your transcript.
Is a 3.8 GPA good for college admissions and scholarships?
Usually, yes. A 3.8 is well above the 3.11 US average and clears every common scholarship line. Selective colleges publish the GPA range of their admitted students in their Common Data Set or class profile, so compare with the colleges on your list; course rigor and test scores decide the rest.
