Easy Grader
Enter the total number of questions on the test and the number of questions answered incorrectly. The calculator will instantly show the grade percentage and display a full grading chart for every possible number of wrong answers.
Average Grade Calculator
Enter your grades and an optional weight for each entry. Weights let you reflect how much each assignment or exam counts toward your final grade. Leave weights blank to calculate a simple equal average. You can also enter a target grade to find out what additional score you need to reach it.
Final Grade Calculator
Find out exactly what score you need on your final exam to finish the course with your desired grade. Enter your current grade, the grade you want to achieve, and the percentage weight your final exam carries in the course.
What Is a Grade?
A grade is a standardized measure used by educational institutions to evaluate and communicate a student’s academic performance on a task, course, or program. Grades may be expressed as percentages, letter grades, points, or grade point averages depending on the institution and country. The letter grading system widely used in North America was first introduced by Mount Holyoke College in 1897. Since then it has become the dominant form of academic assessment in the United States and has influenced grading practices globally.
How to Calculate a Grade Percentage
A grade percentage is calculated by dividing the number of correct answers or points earned by the total possible points and multiplying by 100.
How to Calculate a Weighted Average Grade
When different assignments carry different weights, a weighted average is used. Each grade is multiplied by its weight, the results are summed, then divided by the total weight.
How to Calculate the Grade Needed on a Final Exam
If you know your current grade, your desired final course grade, and the weight of the final exam, you can calculate exactly what score you need on the exam.
Standard Grading Scale (United States)
| Letter Grade | Percentage Range | GPA (4.0 Scale) | Description |
|---|---|---|---|
| A+ | 97 – 100% | 4.0 | Exceptional |
| A | 93 – 96% | 4.0 | Excellent |
| A- | 90 – 92% | 3.7 | Near Excellent |
| B+ | 87 – 89% | 3.3 | Above Average |
| B | 83 – 86% | 3.0 | Good |
| B- | 80 – 82% | 2.7 | Above Satisfactory |
| C+ | 77 – 79% | 2.3 | Slightly Above Average |
| C | 73 – 76% | 2.0 | Average |
| C- | 70 – 72% | 1.7 | Below Satisfactory |
| D+ | 67 – 69% | 1.3 | Poor |
| D | 63 – 66% | 1.0 | Barely Passing |
| D- | 60 – 62% | 0.7 | Minimum Pass |
| F | 0 – 59% | 0.0 | Failing |
Simple Average vs. Weighted Average
A simple average treats every grade equally regardless of how many points each assignment was worth. If you score 80% on a quiz and 90% on a final exam, the simple average is 85% whether the quiz was worth 5 points or the exam was worth 200 points.
A weighted average accounts for the relative importance of each assessment. A final exam worth 40% of the course grade has far greater impact on your final score than a homework assignment worth 5%. Using weights ensures your calculated average accurately reflects how the institution computes your grade. Always check your course syllabus to find the exact weight of each assessment category.
Letter Grade to Percentage Conversion
When entering letter grades, the calculator converts each letter to a representative mid-point percentage. The standard conversions are as follows:
What Is GPA and How Is It Calculated?
GPA stands for Grade Point Average. It is a single number summarizing a student’s academic performance across all courses, calculated by converting each letter grade to a grade point value and averaging those values weighted by credit hours.
Tips for Improving Your Grade
Understanding how grades are calculated gives you actionable insight into where to focus your effort. If your final exam carries 40% of the course grade, it is mathematically far more impactful to prepare thoroughly for that exam than to recover a few points on a low-weight homework assignment. Use the Final Grade Calculator above to determine the exact minimum score you need on remaining work and plan your time accordingly.
A 5-point improvement on a 40%-weight exam has the same effect on your final grade as a 40-point improvement on a 5%-weight quiz. Identifying your highest-weight remaining assessments and directing effort there is the most efficient path to raising your overall grade.
