The short answer
A 3.7 GPA is an A− average on the 4.0 scale — about 90–92% on the common plus/minus scale. It is 92.5% of the way to a 4.0.3.7 GPA as a letter grade and percent
On the standard 4.0 scale, a 3.7 is exactly an A− average.
| Measure | Value |
|---|---|
| Letter equivalent | A− |
| Nearest letter | A− |
| Percent equivalent | 90–92% |
| Share of a 4.0 maximum | 92.5% |
| Share of a 4.33 maximum | 85.5% |
| Gap to the next round number | 0.30 to reach 4.0 |
Percent ranges come from the common plus/minus scale (A− = 90–92%). Your school’s cut-offs may differ — many use a 10-point scale where 90–100 is any A.
What grades add up to a 3.7
With equal-credit classes and whole letters only, a 3.7 means about 70% of your grades are A’s and the rest B’s. The table shows the closest mix for common schedules:
| Classes per semester | Closest whole-letter mix | Exact GPA |
|---|---|---|
| 4 | 3 A, 1 B | 3.75 |
| 5 | 4 A, 1 B | 3.80 |
| 6 | 4 A, 2 B | 3.67 |
| 7 | 5 A, 2 B | 3.71 |
| 8 | 6 A, 2 B | 3.75 |
No two plus/minus grades average exactly 3.7 — you reach it only across three or more classes (or with unequal credits).
How honors and AP classes change a 3.7
Weighted GPAs add a bonus for harder classes — commonly +0.5 for honors and +1.0 for AP, IB or dual enrollment. If a student’s unweighted GPA is 3.7 and some of their six classes are advanced (with the same grades), the weighted number becomes:
| Advanced classes out of 6 | Weighted GPA |
|---|---|
| 1 honors | 3.78 |
| 2 honors | 3.87 |
| 1 AP/IB | 3.87 |
| 2 AP/IB | 4.03 |
| 3 AP/IB | 4.20 |
| 6 AP/IB | 4.70 |
So a weighted 3.7 and an unweighted 3.7 describe different records. Bonus rules are set by each school; the high school GPA calculator shows both numbers from your actual classes.
Raising a 3.7 GPA: what it takes
The further you are into school, the harder a GPA is to move. Example: a 3.7 after 60 credits (about four semesters at 15 credits). The average you’d need on the new credits:
| Target | Over 15 more credits | Over 30 more | Over 60 more |
|---|---|---|---|
| 3.8 | 4.20 — not possible | 4.00 | 3.90 |
| 3.9 | 4.70 — not possible | 4.30 — not possible | 4.10 — not possible |
Reaching 3.8 over two 15-credit terms takes a 4.00 average — roughly an A record. Earlier in school, with fewer credits banked, the same jump is much easier. Plug in your own numbers below.
Is a 3.7 GPA good?
A 3.7 unweighted is a record of mostly A− grades. It sits in the top eighth of the 0–4.0 range numerically, but whether it stands out depends on how hard the classes were and how your school grades.
Context changes what this GPA says about a student:
- Weighted or unweighted. The same transcript can produce both, and they can differ by half a point or more.
- Your school’s scale. A 10-point scale (90 = A) and a 7-point scale (93 = A) turn the same percents into different GPAs.
- The specific requirement. Scholarships, programs and colleges publish their own minimums and often recalculate GPA their own way — check the source, not a rule of thumb.
- Grade inflation. Average high school GPAs rose from 2.68 in 1990 to 3.00 in 2009 (NCES transcript study), so the same GPA meant more a generation ago — see our grade inflation data.
To compare a 3.7 with other values, use the GPA scale converter or check your school’s letter cut-offs on the grading scale converter. To see how this term changes your number, try the cumulative GPA calculator.

Sources & method
- Letter and percent equivalents use the common US plus/minus scale (A 93–100 = 4.0, A− 90–92 = 3.7, B+ 87–89 = 3.3 …). Percents between letters are straight-line estimates; your school's scale may differ — see the grading scale converter.
- All other figures are arithmetic: credit-weighted averages and the formula needed = (target × total credits − current × credits so far) ÷ new credits.
