Testing and Grading Standards
Understanding how a percentage translates into a letter grade and grade points is essential for every student tracking their academic progress. Our grading system follows the standard United States grading scale, where each percentage range corresponds to a specific letter grade — from A all the way down to F — along with a matching grade point value used to calculate your overall GPA.
The following academic letter grades are used to report student achievement: A, B, C, D, and F. A plus (+) or minus (–) may also be applied to most grades, with the exception of A+ and F–. For example, a 94% or above earns an A, an 87% falls into the B+ range, a 74% is a solid C, and anything below 60% is considered a failing grade (F). Students are strongly encouraged to maintain a minimum grade of C (70% or higher) to ensure satisfactory academic progress. Once you know your percentage in each course, you can easily find your overall standing using a GPA Calculator.
Grade Scale
The table below shows the percentage range, the corresponding letter grade, and the grade points assigned to each:
| Percentage | Letter Grade | Grade Points |
|---|---|---|
| 94 – 100 Percent | A | 4.0 |
| 90 – 93.9 Percent | A– | 3.7 |
| 87 – 89.9 Percent | B+ | 3.3 |
| 84 – 86.9 Percent | B | 3.0 |
| 80 – 83.9 Percent | B– | 2.7 |
| 77 – 79.9 Percent | C+ | 2.3 |
| 74 – 76.9 Percent | C | 2.0 |
| 70 – 73.9 Percent | C– | 1.7 |
| 67 – 69.9 Percent | D+ | 1.3 |
| 64 – 66.9 Percent | D | 1.0 |
| 60 – 63.9 Percent | D– | 0.7 |
| 0 – 59.9 Percent | F | 0.0 |
How Percentages Convert to Letter Grades
Many students ask questions like “what percent is an A?” or “what grade is a 64?” The answer depends on where your score falls within the scale above. An A starts at 94%, while the A– range covers 90 to 93.9 percent. The B grades span from 80 to 89.9 percent (B–, B, and B+), and the C grades — often considered the average range — fall between 70 and 79.9 percent. A score of 84%, for instance, is a B, while a 67% lands in the D+ range. Knowing these cut-offs makes it simple to convert any test score, such as 35 out of 50 or 84 out of 100, into a letter grade.
Understanding Grade Points and GPA
Each letter grade carries a grade point value on a 4.0 scale, ranging from 4.0 for an A down to 0.0 for an F. These grade points are what your Grade Point Average (GPA) is built on. Rather than averaging raw percentages, your GPA averages the grade points earned across all your courses. If you want to see exactly where you stand, a High School GPA Calculator can combine all your letter grades into a single GPA in seconds. Students moving on to higher education can use a College GPA Calculator to track their cumulative average across semesters.
Testing & Exams
All students are required to complete course assessments — including quizzes, assignments, and final exams — to demonstrate their understanding of the subject matter. Exams are administered online through our learning platform and must be completed within the assigned timeframe. Each assessment is scored as a percentage, then converted to a letter grade and grade points using the scale above. Academic integrity is expected at all times during testing.
