A grading scale chart converts a test percentage into a letter and, in many schools, GPA points. The full plus/minus table with GPA values appears in the standard chart below.
See the letter grade and 4.0-scale GPA. Anything above 100% counts as the top grade.
The standard grading scale chart: letter grade percentages and GPA
This is the plus/minus scale used by many U.S. high schools and colleges. Each letter has a percentage range and a fixed GPA value on the 4.0 scale. Instructors and schools can shift the cutoffs, so treat it as the common default, not a rule.
| Letter | Percentage | GPA (4.0) | Meaning |
|---|---|---|---|
| A+ | 97–100% | 4.0 | Exceptional mastery |
| A | 93–96% | 4.0 | Excellent understanding |
| A- | 90–92% | 3.7 | Strong performance |
| B+ | 87–89% | 3.3 | Above-average work |
| B | 83–86% | 3.0 | Good, solid understanding |
| B- | 80–82% | 2.7 | Above-average, minor gaps |
| C+ | 77–79% | 2.3 | Satisfactory, some gaps |
| C | 73–76% | 2.0 | Adequate competence |
| C- | 70–72% | 1.7 | Meets minimum standard |
| D+ | 67–69% | 1.3 | Below average, at risk |
| D | 63–66% | 1.0 | Passing, significant gaps |
| D- | 60–62% | 0.7 | Minimum passing |
| F | Below 60% | 0.0 | Failing |

Test score percentage calculator table: correct answers needed by test length
The same percentage means a different number of correct answers on a 10-question quiz than on a 100-question exam. This table shows the fewest correct answers that earn each letter on a 10-point scale. For every individual score, use the easy grader percentage chart for your test length.
| Test length | A (90%+) | B (80%+) | C (70%+) | D (60%+) | F |
|---|---|---|---|---|---|
| 10 questions | 9+ | 8+ | 7+ | 6+ | Under 6 |
| 20 questions | 18+ | 16+ | 14+ | 12+ | Under 12 |
| 50 questions | 45+ | 40+ | 35+ | 30+ | Under 30 |
| 100 questions | 90+ | 80+ | 70+ | 60+ | Under 60 |
On the plus/minus scale the cutoffs are higher for a plain B (83%) and C (73%). Use the EZ grader calculator to switch scales or try any test length, and see how to calculate test grades for partial credit, curves and extra credit.
10-point vs 7-point vs plus/minus scales
Schools do not all draw the lines in the same place. The three setups you will meet most often are below. The same score can land on a different letter depending on which one your school uses.
10-point (letters only)
| Letter | Percentage | GPA (4.0) |
|---|---|---|
| A | 90–100% | 4.0 |
| B | 80–89% | 3.0 |
| C | 70–79% | 2.0 |
| D | 60–69% | 1.0 |
| F | Below 60% | 0.0 |
7-point
| Letter | Percentage | GPA (4.0) |
|---|---|---|
| A | 93–100% | 4.0 |
| B | 85–92% | 3.0 |
| C | 77–84% | 2.0 |
| D | 70–76% | 1.0 |
| F | Below 70% | 0.0 |
Plus/minus (full)
See the full table above. A- starts at 90, B+ at 87, B at 83.
Same score, three scales: 88%
10-point scale: B
7-point scale: B
Plus/minus scale: B+
The 7-point and 10-point setups are approximate descriptions of common patterns, not a list of which schools use which. Your syllabus or district policy is the only reliable source.
The 4-point (0–4) grading scale and 1–4 rubric scores
The 4-point grading scale is the GPA scale: every letter earns a fixed number of grade points from 0 to 4. In its simplest form, an A is 4, a B is 3, a C is 2, a D is 1 and an F is 0. With plus and minus grades the values are A+ 4.0, A 4.0, A- 3.7, B+ 3.3, B 3.0, B- 2.7, C+ 2.3, C 2.0, C- 1.7, D+ 1.3, D 1.0, D- 0.7, F 0.0.
A 4-point scale is not a percentage scale. A school usually turns a percentage into a letter first (for example, with the 10-point scale above), then turns that letter into grade points. The full table of letters, percentages and grade points is in the standard chart.
1–4 rubric scores (standards-based grading)
Some schools grade skills on a 1 to 4 rubric instead of with percentages. That is a different system from the 4.0 GPA scale, and there is no single official way to convert it. Dividing the score by 4 is the simplest method:
| Rubric score | Score ÷ 4 × 100 | If read as a percentage |
|---|---|---|
| 1 out of 4 | 25% | F |
| 2 out of 4 | 50% | F |
| 2.5 out of 4 | 62.5% | D- |
| 3 out of 4 | 75% | C |
| 3.5 out of 4 | 87.5% | B+ |
| 4 out of 4 | 100% | A+ |
Many schools treat a 3 as "meets the standard", which is not the same as a 75% grade, so they use their own conversion. If you need a percentage or a letter for a rubric score, ask your teacher or check the school's grading policy.
Why percentage to GPA is not a simple formula
A shortcut like percentage ÷ 100 × 4 is popular, but it does not match how transcripts work. GPA is band-based: your percentage maps to a letter using fixed cutoffs, and the letter maps to a fixed GPA value. Where you sit inside a band does not matter.
Quick check
84% → B → 3.0 GPA
86% → B → 3.0 GPA (same band, same GPA)
87% → B+ → 3.3 GPA (new band, new GPA)
4.0 scale vs 4.3 scale
On the standard 4.0 scale, an A+ and an A are both worth 4.0. Some schools use a 4.3 scale where the A+ is worth more. The difference only shows up at the top:
| Letter | Percentage | 4.0 scale | 4.3 scale |
|---|---|---|---|
| A+ | 97–100% | 4.0 | 4.3 |
| A | 93–96% | 4.0 | 4.0 |
| A- | 90–92% | 3.7 | 3.7 |
Other grades are often the same on both, but schools differ. When comparing GPAs across schools, check which scale each transcript uses.
GPA to percentage: what percent is a 2.0, 3.0 or 3.5 GPA?
There is no official formula for turning a GPA into a percentage. The honest method is to run the percentage-to-GPA process backwards: find the letter grade that has your GPA, then read its percentage range from the standard plus/minus scale. A GPA that lands exactly on a letter, like 3.0 or 2.0, has a clear range. A GPA in between, like 3.5, is an average across several courses, so the figure below is an estimate halfway between the two neighboring letters.
| GPA (4.0 scale) | Letter grade | Percentage | Type |
|---|---|---|---|
| 4.0 | A / A+ | 93–100% | Exact letter band |
| 3.7 | A- | 90–92% | Exact letter band |
| 3.5 | B+ to A- | about 89% | Estimate |
| 3.3 | B+ | 87–89% | Exact letter band |
| 3.0 | B | 83–86% | Exact letter band |
| 2.7 | B- | 80–82% | Exact letter band |
| 2.6 | C+ to B- | about 79% | Estimate |
| 2.5 | C+ to B- | about 79% | Estimate |
| 2.3 | C+ | 77–79% | Exact letter band |
| 2.0 | C | 73–76% | Exact letter band |
| 1.7 | C- | 70–72% | Exact letter band |
| 1.5 | D+ to C- | about 69% | Estimate |
| 1.3 | D+ | 67–69% | Exact letter band |
| 1.2 | D to D+ | about 66% | Estimate |
| 1.0 | D | 63–66% | Exact letter band |
| 0.7 | D- | 60–62% | Exact letter band |
Treat this as a guide, not an official conversion. Schools set their own cutoffs, and if an application asks for a percentage, use the figure on your transcript or ask your school counselor. To work out a GPA from your course grades, see the GPA calculation steps below.
How to calculate your GPA, step by step
- Convert each course grade to grade points using the table above.
- Multiply the grade points by the course's credits to get quality points.
- Add up the quality points for all courses.
- Divide by the total credits.
| Course | Grade | Grade points | Credits | Quality points |
|---|---|---|---|---|
| English 11 | A- | 3.7 | 3 | 11.1 |
| Algebra II | B | 3.0 | 4 | 12 |
| Biology | B+ | 3.3 | 4 | 13.2 |
| U.S. History | A | 4.0 | 3 | 12 |
| Physical Education | A | 4.0 | 1 | 4 |
| Total | 15 | 52.3 |
GPA = 52.3 ÷ 15 = 3.49. Notice that simply averaging the five grade points would give 3.60, which is wrong because the courses have different credits. Always weight by credits.
High school GPA scale: unweighted vs weighted
Most high schools convert percentages to letters with the 10-point scale (A 90–100%, B 80–89%, C 70–79%, D 60–69%, F Below 60%) or the plus/minus version, then convert each letter to grade points. Many report two GPAs from the same grades:
- Unweighted GPA: every course uses the same 4.0 scale, so the highest possible GPA is 4.0.
- Weighted GPA: harder courses add bonus points, commonly 0.5 for Honors and 1.0 for AP, IB or dual enrollment, so the highest possible GPA is usually 5.0. Some districts use different bonuses or caps.
Here is the same transcript counted both ways, with every course worth the same credits:
| Course | Level | Grade | Unweighted | Weighted |
|---|---|---|---|---|
| English 11 | Regular | A- | 3.7 | 3.7 |
| Algebra II | Regular | B | 3.0 | 3.0 |
| Biology | Honors | A | 4.0 | 4.5 |
| U.S. History | AP | B+ | 3.3 | 4.3 |
| Spanish II | Regular | A- | 3.7 | 3.7 |
| GPA | 3.54 | 3.84 |
The weighted figure is higher because two courses earned a bonus. Some colleges recalculate a GPA with their own method, so use the number on your transcript unless an application says otherwise. The full bonus table for every letter is in the weighted GPA section below.
Weighted GPA: Honors, AP and IB
Many high schools give extra points for harder classes. A common policy adds 0.5 for Honors and 1.0 for AP, IB or dual enrollment, which lifts the top of the scale from 4.0 to 5.0. Policies differ by district, and some schools only add the bonus for grades above a certain level.
| Letter | Regular | Honors (+0.5) | AP / IB (+1.0) |
|---|---|---|---|
| A+ | 4.0 | 4.5 | 5.0 |
| A | 4.0 | 4.5 | 5.0 |
| A- | 3.7 | 4.2 | 4.7 |
| B+ | 3.3 | 3.8 | 4.3 |
| B | 3.0 | 3.5 | 4.0 |
| B- | 2.7 | 3.2 | 3.7 |
| C+ | 2.3 | 2.8 | 3.3 |
| C | 2.0 | 2.5 | 3.0 |
| C- | 1.7 | 2.2 | 2.7 |
| D+ | 1.3 | 1.8 | 2.3 |
| D | 1.0 | 1.5 | 2.0 |
| D- | 0.7 | 1.2 | 1.7 |
| F | 0.0 | 0.0 | 0.0 |
This table assumes the bonus applies to every passing grade and that an F stays at 0. Confirm your school's weighting rules in the student handbook.
How to use an EZ grader with a chart, step by step
A chart and a calculator do different jobs. The chart makes a whole stack of same-length tests fast, and the calculator checks the odd ones. Using both cuts down on arithmetic slips because you never divide by hand.
- Confirm your scale. Check the syllabus or handbook for cutoffs and plus/minus grades (see which scale your school uses).
- Print the chart for your test length. Pick it from the printable EZ grader charts, or open the 25-question chart for a quiz like the example below.
- Mark each paper and write the number wrong at the top. Counting wrong answers is usually quicker and less error-prone than counting correct ones.
- Read the row. Find that number in the chart and copy the percentage and letter next to it.
- Spot-check with the calculator. Enter a few papers, especially ones near a cutoff, into the EZ grader. Cutoffs apply to the exact score, so 89.6% is a B+, not an A-.
- Record the final scores in your gradebook. It is the official record, so treat the chart and calculator as working tools.
Example: a 25-question quiz
Paper 1: 4 wrong, so 21 ÷ 25 = 84%. B on a 10-point scale, B on plus/minus.
Paper 2: 7 wrong, so 18 ÷ 25 = 72%. C on a 10-point scale, C- on plus/minus.
Paper 2 shows why the scale matters: the same score earns a different letter on each one.
Which scale does my school use?
You do not have to guess. These are the places where the scale is actually published:
- The course syllabus. It usually lists the cutoffs, and these override the school default.
- The student handbook or district grading policy. It covers plus/minus grades, weighted courses and minimum passing marks.
- The grading key on your transcript. It shows how the school converts letters to GPA.
- Your gradebook portal. Many show the scale next to each course.
- Your teacher or counselor. Ask directly if the documents are silent.
Once you know the scale, the average grade calculator turns your category scores into a course grade, the final grade calculator shows what you need on the final exam, and our complete guide on how to calculate grade after final exam walks you through every step.
Borderline grades and rounding
On the plus/minus scale, an exact 89.5% is a B+, and 90% is an A-. Whether 89.5% gets rounded up depends on the instructor.
Some instructors round up
A score of 89.5% becomes 90% and earns the A-.
Others use the exact number
89.5% stays a B+, with no rounding adjustment.
If you do round, round once at the very end rather than rounding earlier scores, which can push a total across a line it has not really crossed. The syllabus is the only reliable way to know the policy.
A short note on where letter grades came from
Letter grades are a fairly recent convention. Early American colleges used descriptive marks and numerical scores, and the A to F system spread gradually through the late 1800s and early 1900s, with Mount Holyoke College often cited as an early adopter of a letter scale in the 1890s. GPA came later as a way to compare performance across courses. Sources differ on the exact details, so treat this as background, not a precise timeline.
Common mistakes with grading charts
- Assuming every school uses the same cutoffs. A 90% can be an A or an A-.
- Using a linear formula for GPA. GPA is band-based, not proportional.
- Averaging GPA without credits. A 1-credit class should count for less than a 4-credit one.
- Comparing weighted and unweighted GPAs. A 4.4 weighted GPA is not better than a 4.0 unweighted one by default.
- Treating an F as a 0% grade. An F covers everything below the cutoff, from 59% down to 0%.
Frequently asked questions
What is the standard grading scale in U.S. schools?
The most common scale is: A 90–100%, B 80–89%, C 70–79%, D 60–69%, F Below 60%. Many schools add plus and minus grades, where A- starts at 90%, B+ at 87%, B at 83% and so on down to D- at 60%. Individual schools and teachers set their own cutoffs, so confirm yours in the syllabus or student handbook.
Is a 60% an F or D?
It depends on the grading scale. On the common U.S. plus/minus scale shown here, 60% is a D-. On a letter-only 10-point scale, 60% is a D. Some schools set different cutoffs, so check your course syllabus or school policy.
What is the grading scale 1, 2, 3, 4?
A 1–4 scale often means a standards-based rubric: 1 means beginning, 2 developing, 3 meeting the standard, and 4 exceeding it. It is not automatically the same as a percentage or a 4.0 GPA scale. Schools define their own rubric descriptions and conversions.
What percentage is an A?
On the common 10-point scale, 90% to 100% is an A. On the plus/minus scale, 97% to 100% is an A+, 93% to 96% is an A and 90% to 92% is an A-. On a 7-point scale, an A starts at 93%.
What percentage is each letter grade?
On the standard plus/minus scale: A+ 97–100%, A 93–96%, A- 90–92%, B+ 87–89%, B 83–86%, B- 80–82%, C+ 77–79%, C 73–76%, C- 70–72%, D+ 67–69%, D 63–66%, D- 60–62%, F Below 60%. On the 10-point scale without plus or minus: A 90–100%, B 80–89%, C 70–79%, D 60–69%, F Below 60%.
What is 85 percent as a letter grade?
On the plus/minus scale, 85% is a B (83% to 86%), worth 3.0 GPA points. It is also a B on the 10-point letter-only scale and on the 7-point scale, where 85% is the lowest B.
Is 70 percent passing?
On the standard plus/minus scale, 70% is a C-, which is passing. On a 7-point scale it is the lowest D. Some schools or programs require a higher minimum (such as 65% or 70%) for credit or for a prerequisite, so check your own policy.
What GPA is a B, and what percentage is that?
A B is 3.0 on the standard 4.0 scale and 83% to 86% on the plus/minus scale (80% to 89% if your school uses plain letters). B+ is 3.3 and B- is 2.7.
Can I convert a percentage to GPA with a simple formula?
No. A percentage first maps to a letter grade using fixed cutoffs, and the letter maps to a fixed GPA value. That is why 84% and 86% both give 3.0, while 87% (B+) gives 3.3. A linear formula like percentage ÷ 100 × 4 would give each of those a different number.
What percentage is a 3.5 GPA?
A 3.5 GPA sits between a B+ (3.3) and an A- (3.7), which works out to about 89% on the standard plus/minus scale. This is an estimate: a GPA like 3.5 is an average across several courses, and no official formula turns it into one percentage.
What percentage is a 2.0 GPA?
A 2.0 GPA is a C, which is 73–76% on the plus/minus scale and 70–79% on the 10-point scale. A cumulative 2.0 can also come from a mix of higher and lower grades, so treat the percentage as approximate.
What is the 4.0 grading scale?
The 4.0 scale gives each letter a fixed number of grade points: A+ 4.0, A 4.0, A- 3.7, B+ 3.3, B 3.0, B- 2.7, C+ 2.3, C 2.0, C- 1.7, D+ 1.3, D 1.0, D- 0.7, F 0.0. In its simplest form, A is 4, B is 3, C is 2, D is 1 and F is 0. Some schools give an A+ 4.3 instead of 4.0.
What is the difference between a 4.0 and a 4.3 GPA scale?
On the standard 4.0 scale, A+ and A are both worth 4.0. Some schools use a 4.3 scale where an A+ is worth 4.3. Check which scale your transcript uses before comparing GPAs across schools.
What is the difference between unweighted and weighted GPA?
An unweighted GPA counts every course on the same 4.0 scale. A weighted GPA adds bonus points for harder courses, commonly 0.5 for Honors and 1.0 for AP or IB. In the example on this page, the same five grades give 3.54 unweighted and 3.84 weighted.
What is a weighted GPA?
A weighted GPA adds bonus points for harder courses. A common policy adds 0.5 for Honors and 1.0 for AP, IB or dual enrollment, so an A can count as 4.5 or 5.0. Policies vary by district, so check your handbook.
What percentage is a 3 out of 4 on a 1 to 4 scale?
Dividing gives 75%, since 3 ÷ 4 × 100 = 75. But 1 to 4 scores usually come from standards-based grading, and many schools treat a 3 as meeting the standard rather than as a 75% grade, so they use their own conversion. A 3.5 out of 4 is 87.5% by division. Ask your school which conversion it uses.
How do I calculate my GPA?
Convert each course grade to grade points, multiply by its credits, add up those quality points, and divide by total credits. In the example on this page, 52.3 quality points over 15 credits is a 3.49 GPA.
What is the difference between the 10-point and 7-point grading scales?
They set different cutoffs. On the 10-point scale an A starts at 90%, a B at 80%, a C at 70% and a D at 60%. On the 7-point scale an A starts at 93%, a B at 85%, a C at 77% and a D at 70%. The same 88% is a B on the 10-point scale and a B on the 7-point scale, but a B+ once plus and minus grades are added.
Is the grading scale the same in high school and college?
Not necessarily. Both commonly use the A to F letters and a 4.0 GPA scale, but cutoffs, plus/minus grades, weighting and rounding are set by each school or instructor. A college syllabus usually spells out its own scale.
What does a college grading scale chart look like?
Many colleges use letter grades from A to F and a 4.0 GPA scale, sometimes with plus and minus grades. The percentage cutoffs vary by institution and course, so a college grading scale chart is a useful general reference, but your syllabus and registrar policy determine your actual grade.
How are borderline grades like 89.5% handled?
It depends on the instructor. On the plus/minus scale, an exact 89.5% is a B+, and 90% is an A-. Some instructors round up and others do not, so check the syllabus.
What is an easy grader percentage chart?
An easy grader percentage chart is a table that lists every possible score on a test of a given length, with the matching percentage and letter grade. You count the wrong answers on a paper, find that number in the table, and read the grade from the same row. You can print one for common test lengths on the printable EZ grader chart page.
How many questions can I miss on a 20-question test and still get a B?
On a 10-point scale, where a B starts at 80%, you can miss 4 questions (16 correct). On the plus/minus scale a B starts at 83%, so you can miss 3 (17 correct, which is 85%). Missing 4 on the plus/minus scale gives 80%, a B-.
How do I convert a test score to a letter grade?
Divide the points earned by the points possible and multiply by 100, then find that percentage in your school's scale. For example, 21 out of 25 is 84%, which is a B on the 10-point scale and a B on the plus/minus scale.
What is the fastest way to grade a stack of tests?
If every paper has the same number of questions, print the chart for that length, count the wrong answers on each paper, and read the percentage and letter from one row. Re-check a few papers near a cutoff with the EZ grader calculator, then enter the final scores in your gradebook, which is the official record.
