How to calculate weighted grade average?

• First multiple the grade received by the weight of the assignment. Repeat this for each completed assignment.
• Then add each of the calculated values from step 1 together.
• Next add the weight of all the completed assignments together.
• Finally, divide the calculated value from step 2 above by the value calculated from step 3. This gives you the weighted grade average.

Weighted Grade Formula

Weighted Grade = (w 1 x g 1 + w 2 x g 2 + w 3 x g 3 + …) / (w 1 + w 2 + w 3 + …)

Example Calculation

Here is an example. Let's say you received a 90% on your first assignment and it was worth 10% of the class grade. Then let's assume you took a test and received an 80% on it. The test was worth 20% of your grade.

To calculate your average grade, follow these steps:

• Multiple each grade by its weight. In this example, you received a 90% on the first assignment and it was worth 10%. So multiply 90 x 10 = 900. You also received an 80% on the test and it was worth 20% of the class grade. So multiply 80 x 20 = 1600.
• Add the calculated values from step 1 together. We now have 900 + 1600 = 2500.
• Add the weight of all the completed assignments together. To do this, add 10% for the first assignment and 20% for the second assignment. That gives us 10 + 20 = 30.
• Finally, divide the value from step 2 by the value from step 3. That gives us 2500 / 30 = 83.33. Therefore our weighted grade average is 83.33%.

Brief history of different grading systems

In 1785, students at Yale were ranked based on "optimi" being the highest rank, followed by second optimi, inferiore (lower), and pejores (worse). At William and Mary, students were ranked as either No. 1, or No. 2, where No. 1 represented students that were first in their class, while No. 2 represented those who were "orderly, correct and attentive." Meanwhile at Harvard, students were graded based on a numerical system from 1-200 (except for math and philosophy where 1-100 was used). Later, shortly after 1883, Harvard used a system of "Classes" where students were either Class I, II, III, IV, or V, with V representing a failing grade. All of these examples show the subjective, arbitrary, and inconsistent nature with which different institutions graded their students, demonstrating the need for a more standardized, albeit equally arbitrary grading system.

In 1887, Mount Holyoke College became the first college to use letter grades similar to those commonly used today. The college used a grading scale with the letters A, B, C, D, and E, where E represented a failing grade. This grading system however, was far stricter than those commonly used today, with a failing grade being defined as anything below 75%. The college later re-defined their grading system, adding the letter F for a failing grade (still below 75%). This system of using a letter grading scale became increasingly popular within colleges and high schools, eventually leading to the letter grading systems typically used today. However, there is still significant variation regarding what may constitute an A, or whether a system uses plusses or minuses (i.e. A+ or B-), among other differences.

An alternative to the letter grading system

Letter grades provide an easy means to generalize a student's performance. They can be more effective than qualitative evaluations in situations where "right" or "wrong" answers can be easily quantified, such as an algebra exam, but alone may not provide a student with enough feedback in regards to an assessment like a written paper (which is much more subjective).

Although a written analysis of each individual student's work may be a more effective form of feedback, there exists the argument that students and parents are unlikely to read the feedback, and that teachers do not have the time to write such an analysis. There is precedence for this type of evaluation system however, in Saint Ann's School in New York City, an arts-oriented private school that does not have a letter grading system. Instead, teachers write anecdotal reports for each student. This method of evaluation focuses on promoting learning and improvement, rather than the pursuit of a certain letter grade in a course. For better or for worse however, these types of programs constitute a minority in the United States, and though the experience may be better for the student, most institutions still use a fairly standard letter grading system that students will have to adjust to. The time investment that this type of evaluation method requires of teachers/professors is likely not viable on university campuses with hundreds of students per course. As such, although there are other high schools such as Sanborn High School that approach grading in a more qualitative way, it remains to be seen whether such grading methods can be scalable. Until then, more generalized forms of grading like the letter grading system are unlikely to be entirely replaced. However, many educators already try to create an environment that limits the role that grades play in motivating students. One could argue that a combination of these two systems would likely be the most realistic, and effective way to provide a more standardized evaluation of students, while promoting learning.

How to Calculate a Weighted Grade

Understanding how to calculate a weighted grade is essential for both students and educators. In many educational settings, not all assignments or exams carry the same importance in the overall class grade .

Some might be worth more of the overall grade than others. For instance, a final exam often contributes more to a final grade than a single homework assignment. This is referred to as a weighted grade .

A weighted grade is essentially a weighted average , and you can calculate it using a formula based on the weighted average formula.

Weighted Grade Formula

To calculate a weighted grade, you can apply the weighted average formula:

Thus, a weighted grade is equal to the sum of the products of each grade and its weight, divided by the sum of the weights.

The total weight is typically the sum of all weights, which often equals 1 (or 100% if you’re working in percentages).

For example, let’s consider a student who has taken three tests in a course. The first test is worth 30% of their final grade, the second test is worth 40%, and the third is worth 30%.

Let’s say the student scored 80% on the first test, 90% on the second, and 85% on the third. Here’s how you’d calculate the weighted grade:

Thus, the student’s weighted grade is 85.5%.

Final grade calculator

Have you ever tried to calculate your Grades based on Assignments, Quizzes, Presentations, Midterm Exams, and Final Exams? And have you failed to calculate the GPA or Grade for a course?

Weighted Grade Calculator is going to help you calculate that. It is a Grader which calculates the average weighted grades of a class or course. Weighted Grading is not a proper Grading system but an approach for assessment. By assigning varied weights to assignments, quizzes, presentations, midterms, and Final exams, weighted Grades for a course are calculated. Also in the US Grading Scheme Class participation is considered in weighted grades calculation.

How does It work?

The Weighted Grade Calculator works by taking inputs such as the name of each assessment (e.g., quizzes, assignments, midterm, final), the percentage grade obtained in each assessment, and the weights assigned to each assessment. Assessment factors can also be other than traditional exams etc for different courses and institutions.

Using this information, the calculator calculates the average weighted grade in percentage and determines the corresponding letter grade based on standard grading scales.

For example, if a student scored 80% on quizzes (weighted 20%), 90% on assignments (weighted 30%), and 85% on the final exam (weighted 50%), the calculator would compute the overall weighted grade and provide the corresponding letter grade, such as an A-, B+, etc.

This allows both teachers and students to accurately assess performance and understand the impact of each assessment on the final grade.

How Weights are Assigned?

The Final Marks/Grades are calculated based on the importance assigned (weights) to a particular assignment or exam. Different weights are assigned to assignments, quizzes, presentations, and exams based on their importance. For instance, assignments might carry 30% of the total grade, quizzes 20%, and exams 50%. These weights reflect the importance of each assessment method in evaluating the student’s performance throughout the course.

Weighted Grade calculation may be applied for the final grade calculation of a single course as well as a whole class or batch.

Advantages of Weighted Grading

Weighted Grades add to a significant importance in evaluating students’ performance. Also, this ensures a justified evaluation of students.

Reflects Significance

In weighted grading, teachers prioritize specific tests or assignments they believe are crucial for assessing student learning. They focus on these to gauge students’ understanding.

For instance, exams might count more than assignments and quizzes because they cover more topics and need students to understand things more deeply.

Flexible Weighting Systems in Education

Teachers can adjust how they weigh different parts of the grade to match the goals and setup of the class. This lets them focus more on certain kinds of tests or assignments depending on what they want students to learn or what the class needs.

Boosting Student Motivation Through Weighted Grading

Weighted grading helps students focus on important assignments or tests because they know those affect their final grades the most. For example, knowing that exams count a lot can make students study harder for them. Also, they participate in all class activities like assignments and quizzes, since they count in final grading.

Empowering Students Through Transparent Grading Practices

Weighted grading tells students how much each test or assignment matters for their final grade right from the start. This makes it easier for students to know what to focus on and how to plan their time wisely. This makes the overall grading a transparent practice for evaluation.

Enhancing Fairness and Accuracy

Weighted grading tries to show how well students are doing overall more accurately. It does this by focusing more on tests and assignments that check how much students understand the material. This can make it fairer when grading students’ work.

Recognizing Diversity in Assessments

In weighted grading, teachers can tell the difference between different kinds of tests, like homework, quizzes, projects, class participation, and exams. This shows that each type of assignment needs different amounts of work and skill.

In conclusion, the Weighted Grade Calculator serves as a valuable tool for both teachers and students in accurately assessing and understanding academic performance. By assigning appropriate weights to different assessments, such as exams, quizzes, projects, class participation, and homework, the calculator provides a clear picture of overall progress. For educators, it facilitates fair and transparent grading practices, allowing for tailored assessment strategies aligned with course objectives. Meanwhile, students benefit from a better understanding of how their efforts contribute to their final grades, empowering them to set realistic goals and manage their time effectively. Overall, the Weighted Grade Calculator promotes accountability, transparency, and fairness in the evaluation process, ultimately enhancing the learning experience for all involved.

• Input Grades and Weights: Start by entering the grade you received for an assignment in the “Grade” field. Next, input the corresponding weight (in percentage) of that assignment in the “Weight” field.
• Add Entries: Click the “+ Add” button to include the grade and weight in your calculation. Repeat this step for all your assignments.
• Remove Entries: If you need to remove an entry, click the “Remove” button next to the respective grade and weight.
• Calculate: Once all entries are added, the calculator will automatically compute your weighted grade and display it at the bottom.

Example Calculation

Let’s break it down with an example. Suppose you have the following grades and weights:

• Assignment 1: Grade = 85, Weight = 20%
• Assignment 2: Grade = 90, Weight = 30%
• Assignment 3: Grade = 78, Weight = 50%

Here’s how the calculation would look in a fun and engaging way:

So, your final weighted grade is 83! Just like magic, but without the wand.

    How to calculate your grade

With the help of this grade calculator you can calculate your current weighted grade or unweighted grade in terms of percentage, letter grade, or GPA. The tool will also output the weight of all remaining exams, and assignments and has the option of calculating the minimum score you need to obtain on a final exam in order to achieve a target overall grade for a class or course.

To use the calculator, enter the number of grades you currently have, then each grade as a percent or letter grade , and finally the weight each grade adds towards the overall. If no weights are entered, the weights are assumed equal and the calculator will output the unweighted average grade. Otherwise a weighted average grade will be produced in terms of percentage, GPA, and a letter grade.

    What grade do I need on my final?

If you haven't yet got a score on the final exam for a given class, you can use this tool as a final grade calculator. In order to achieve a given grade goal for the entire class, course, or semester, a given minimum grade is required on the final exam, depending on both the weighted average grade to that date, and the weight of the final on the overall grade. This minimum required score can be calculated using the following formula:

Required final score = (Grade Goal - Current Grade x (100% - Weight of Final(%))) / Weight of Final(%)

The current grade is calculated based on the weighted average of all marks to date. The weight of the final test is calculated as 100% minus the combined weight of all grades to date. Therefore, if the combined weight of the scores you enter is 65% then the final exam will have a weight of 100% - 65% = 35%.

    How to convert a grade to percentage?

Our grade calculator uses the following table to convert letter grades to percentages. Note that since this is not a universally applicable table, ideally one would want to know the exact percentage scores and use these as input for the calculator, otherwise the results may be slightly off.

Again, it is our recommendation that you check with your local school or college and enter percentage grades instead of letter grades for the most accurate calculation. Note that while U.S. colleges and schools are likely to use the above grading, educational institutions in other countries may use a vastly different GPA scale.

If you want to calculate the grade needed on the final exam to achieve a desired overall grade, please use our Final Grade Calculator .

What is a weighted grade?

A weighted grade is one in which all the assessments in a course have different degrees of importance, or "weight." For example, a course may involve homework, quizzes, exams, projects, presentations, and more. Typically, exams have a larger weight than quizzes and homework, since exam results are often considered to be the most important assessment in a course.

As an example, a course may have exams that account for 50% of the final grade, while quizzes make up 30%, and homework makes up 20%. This means that a 95 on a homework assignment and a 95 on an exam do not carry the same weight; a 95 on an exam has more of an effect on the final grade than a 95 on a homework assignment because it has a larger weight.

How weighted grade is calculated?

There are different formulas for calculating weighted grades depending on the information available. This calculator assumes a total weight of 100 and uses the following formula to calculate the weighted grade, where w i is the weight of the respective grade g i :

For example, given the following grades and respective weights,

the weighted grade is computed as follows:

92.75 is the current weighted grade based on the grades achieved thus far. Since the calculator assumes a total weight of 100, there are still remaining grades that together have a weight of 80. Once the values of the remaining grades and their weights are known, the final weighted grade can be computed in the same manner as above. In cases where the assessments (exams, quizzes, homework, etc.) have weights in terms of percentages, the weighted grade can be computed by finding the average grade attained for each assessment, then multiplying by their respective weights. Given that w i is the weight in percentage form of the average grade g i achieved in each respective assessment: Weighted grade = w 1 g 1 + w 2 g 2 + w 3 g 3 + ...+ w n g n For example, given that a student's homework is worth 20%, quizzes are worth 30%, and exams are worth 50%, if a student achieved an average grade of 85 on all their homework assignments, an average of an 87 on all their quizzes, and an average of 83 on all their exams, their weighted grade is calculated as follows:

(85)(0.2) + (87)(0.3) + (83)(0.5) = 84.6

Thus, their weighted grade is an 84.6.

What are the different grade formats?

The calculator uses three different grade formats: percentage, letter, and point value.

Percentages:

Percentage grades are grades expressed in percentage form. They range from 0-100%, and are calculated by dividing the score earned by the student by the total possible score on the assessment. For example, consider a multiple-choice exam in which all the questions are worth the same number of points. To calculate a student's percentage grade, divide the number of questions the student answered correctly by the total number of questions, then multiply by 100. This is the student's percentage grade. For example, if a student answered 39/50 questions correctly on an exam, their percentage grade is:

Percentage grades are related to letter grades through a grading scale. Grading scales vary throughout institutions, so an A at one school may not correspond to the same percentages as another. Refer to the table below in the "Letter grades" section to see how percentages and letter grades are related in one of the more commonly used grading scales in the US.

Letter grades:

Letter grades range from A-F in the US grading system, where an A is the highest achievable grade, and an F is a failing grade. However, even within the US system, there are variations in what each letter represents, as well as in the letters used in the system. For example, there are institutions that use grades such as A+, B-, C+, etc., while there are others that do not make use of plus and minus grades, and only use the letters A, B, C, D, and F. Also, depending on the institution, a D, or even a C, might constitute a failing grade for the course.

Letter grades correspond to a specific range of percentage values. The range of values assigned to a given letter differ based on the grading scale, but are generally pretty similar. The following table shows a commonly used grading scale, and the corresponding letter and percentage grades.

Point value:

Point value grades refer to grades where the points earned for all assessments in the course are summed; the grade achieved in the course is calculated by dividing the total number of points earned by the total number of points possible. There can be any number of points in this type of grading system.

For example, a course may have 10 homework assignments worth 20 points each, 5 quizzes worth 50 points each, and 3 exams worth 150 points each. To be able to determine the weight of each type of assessment, it is necessary to find the total number of points for all the assessments in the course. In this case,

10(20) + 5(50) + 3(150) = 900

Thus, the course has a total of 900 points making homework worth 22.2% of the final grade, quizzes worth 27.8%, and exams worth 50%. We can also determine how much each individual assessment is worth. For this example, each homework assignment is 2.2%, each quiz is 5.5%, and each exam is 16.67% of the final grade.
