You scored 31 out of 35 on a test. What percentage is that, and is it a good grade?
31 out of 35 equals 88.57%. On the standard U.S. 10-point scale, that is a B+, worth about 3.3 GPA points. It is a strong grade that sits 1.57 points above the 87% B+ line and 1.43 points below an A–.
This guide covers the percentage, letter grade, GPA, rounding, and what a 31/35 means inside a weighted course.
Key Takeaways
- 31 out of 35 = 88.57%, which is a B+ on the standard U.S. scale (87–89%).
- On the 4.0 GPA scale, a 31/35 converts to 3.3 GPA points (3.0 at schools without plus/minus grades).
- Each question on a 35-point test is worth 2.86%. One more correct answer (32/35 = 91.43%) would lift this to an A–.
What Is 31 Out of 35 as a Percentage?
Formula:
(Points Earned ÷ Total Points) × 100 = Percentage Grade
Applied:
(31 ÷ 35) × 100 = 0.8857 × 100 = 88.57%
The fraction 31/35 cannot be simplified, because 31 is prime and does not divide 35. The decimal repeats (0.885714…), so the percentage is rounded to two places. To learn the method for any score, see how to calculate grade percentage, or check any result with the percentage calculator.
Worked Step-by-Step Examples
Example 1: Basic Percentage Conversion
A student misses 4 questions out of 35 and scores 31/35.
- Step 1: Divide points earned by total points → 31 ÷ 35 = 0.8857
- Step 2: Multiply by 100 → 0.8857 × 100 = 88.57%
- Step 3: Match it to the letter scale → B+
Example 2: How Close Is 31/35 to the Next Tier?
- Points needed for 87% (B+): 35 × 0.87 = 30.45 → you earned 31, so you clear it by 0.55 points.
- Points needed for 90% (A–): 35 × 0.90 = 31.5 → you are 0.5 points short.
- Next whole score up: 32/35 = 91.43%, an A–.
One more correct answer moves you from B+ to A–. One fewer, 30/35, is 85.71%, a B.
Example 3: A 31/35 Test Inside a Weighted Course Average
Say a student has:
- Homework (20% of grade): 85%
- Test (30% of grade): 88.57% (their 31/35)
- Final Exam (50% of grade): 84%
Weighted Grade = (Score₁ × Weight₁) + (Score₂ × Weight₂) + (Score₃ × Weight₃)
Weighted Grade = (85 × 0.20) + (88.57 × 0.30) + (84 × 0.50) = 17.0 + 26.57 + 42.0 = 85.57%
The course grade lands at a B, one tier below the test score. See how to calculate weighted average grades for the full method.

Percentage-to-Letter Grade Scale Used Above
| Percentage Range | Letter Grade | Performance Level |
|---|---|---|
| 97% – 100% | A+ | Outstanding |
| 93% – 96% | A | Excellent |
| 90% – 92% | A– | Excellent |
| 87% – 89% | B+ | Very Good (31/35 falls here) |
| 83% – 86% | B | Good |
| 80% – 82% | B– | Above Average |
| 77% – 79% | C+ | Above Average |
| 73% – 76% | C | Average |
| 70% – 72% | C– | Below Average |
| 67% – 69% | D+ | Poor |
| 63% – 66% | D | Barely Passing |
| 60% – 62% | D– | Barely Passing |
| Below 60% | F | Failing |
This is the standard 10-point scale used by most U.S. schools. On a stricter 7-point scale, 88.57% would be a B (the B range there is 85–92%). Compare your school’s cutoffs with the grade scale and grading chart guides, or see different grading scales.
What GPA Is 31 Out of 35?
On the standard unweighted 4.0 scale, a B+ converts to 3.3 GPA points. Schools without plus/minus grades count it as a flat 3.0 (a B).

| Course Level | GPA Bonus | B+ (88.57%) GPA Value |
|---|---|---|
| Standard | +0.0 | 3.3 |
| Honors | +0.5 | 3.8 |
| AP / IB | +1.0 | 4.3 |

Is 31 Out of 35 a Good Grade?
Yes. An 88.57% is a strong score, well above the typical class average of 75–80%. It earns a B+ at schools with plus/minus grades and a B at schools without them.
How Rounding Affects a 31/35
Because 88.57% is near the top of the B+ range (87–89%), rounding policy matters:
- Round to the nearest whole percent: 88.57% → 89% → B+
- Truncate (drop decimals): 88.57% → 88% → B+
- Use exact decimals: 88.57% is between 87 and 90 → B+
All common policies give a B+. It would take a school that rounds 89.5% and above to an A– to change a score, and 88.57% is not close to that. For a true borderline case, see is 89.5 an A or B?
International Grade Comparison
| Country / System | Approximate Equivalent of 31/35 (88.57%) |
|---|---|
| United States | B+ (3.3 GPA) |
| United Kingdom (university) | First-class (70%+) |
| France (0–20 scale) | 17.71/20 — Très Bien |
| Germany (1.0–5.0, 1 best) | About 1.3–1.7 — Sehr gut to Gut |
| Canada | A (80–89% in many provinces) |
The same score can look very different depending on the country. An 88% is a first-class result at a UK university and an A in many Canadian provinces, but a B+ in the U.S.
Practical Tips: Raising a 31/35 to an A–
- Review the 4 missed questions. Look for patterns: one topic, one question type, or time pressure.
- Ask about partial credit. On a 35-point test, half a point is worth 1.43%. One extra point would take you to 91.43%.
- Practice with active recall. Flashcards and practice tests beat re-reading notes.
- Know how much the test counts. See how much is a test grade worth before deciding how much effort to spend.
- Plan ahead. Use a what grade do I need calculator to see what you need on future work to reach your target grade.
- Teachers: if a test average looks low, consider curving test grades.
