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.

Calculate your uni grade

Our university grade calculator takes a percentage mark for each of your university courses (assignments or modules) or academic years, together with the percentage or credit weighting, and returns a weighted average for the parts you have completed so far.

How do I calculate my weighted university grade?

In order to work out your weighted average grade for your university year, module, or assignment, we take the marks (or grades) multiplied by their respective weights, sum them together, and then divide the total by the sum of the weights. An example is shown below, and the calculation is shown at the bottom of the results.

Example calculation

Student A is studying a degree in Computer Science and has undertaken three modules so far. They want to calculate their average weighted grade for the three modules.

Student A's average mark is therefore calculated at 64.5%.

Unweighted calculations

If you wish to carry out an unweighted calculation, simply leave all the weight boxes blank, or make them equal. If you want to work out the mark you require on your final exam, you can use our final grade calculator tool .

What mark do I need from the rest of my course?

Our calculator can help you work out the average mark you need from the remainder of your course, in order to achieve a target percentage, so that you can see whether you're on track to achieve the grade you want.

If you have any problems using our university grade calculator, please contact us .

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%.

Important Notes

You can use our grade calculator to calculate the final exam grade you will need to achieve the overall course grade you desire. Our calculator requires you to enter the current percentage grade you have currently obtained for that course together with the weight of the final exam as a percentage value. However, if you do not know what your current grade is, for the question "Do you know your Current Grade?" select the answer "no." Enter the grades you have received for all of your assignments, homework, test, labs, and anything else that contributes to your final grade, as well as the weight of each grade. Our grade calculator will automatically calculate not only your current grade but the grade you need to achieve on your final exam to achieve the overall course grade you desire. In addition, both the minimum and maximum course overall grades will be provided.

Once you have entered the information required, the system will generate both a table and a chart that show the different final exam grades you may obtain as well as the overall course grades that go with them.

Inputting Data in our Grade Calculator

When entering your current grade and the weight of your final exam, our calculator will assume that your current grade has been based on the weight of the course prior to your final exam and calculates it as the input weight subtracted from 100%. If your current grade hasn't taken your coursework into account, the generated results will not be accurate.

Similar to the above, if you don't know what your current grade is and you enter both the coursework grades and the associated weights into the calculator, the calculator will automatically calculate your current grade and the weight of the final exam. In this situation, the weight of your final exam is calculated by taking the sum of the weight of your course work subtracted from 100%. With that in mind, if you enter too many or not enough assignments, the weight of the final exam that is calculated will most likely not match the actual weight of the final exam in your chosen course.

How to Calculate the Percentage of a Grade

How to Calculate Grades With Weights

Use addition and division to calculate your grade on an individual assignment or test, your progress in class and your final class grade. For weighted grading systems, you'll also have to multiply assignment or class scores by the assigned weight.

If assignments come with different point values, each one will be worth a specific percentage of your overall grade. In that case, some assignments will count more toward your class grade than others will. Follow these steps for both straightforward and weighted point systems.

Tip: Consider using a free online grade calculator to help keep track.

1. Calculate Percentage

Calculate the percentage you earned on one specific grade. To do this, take the total number of points you earned on the assignment and divide by the number of points the assignment was worth. If, for example, you earned 38 points out of a total possible 50 points, then your percentage is 76, as shown here: 38 / 50 = .76 or 76 percent. This is generally considered to be a "C" grade on a standard grading scale.

2. Determine assignment percentage

Determine the percentage of a class grade for one specific assignment. For this, you will need to take the possible points for every assignment in the class and add them together, and then divide the possible points for the specific assignment in question by the possible points for the course. If, for instance, a course has a total of 1,000 possible points and yesterday's test was worth 200 points, then you would divide 200 by 1000. That means that yesterday's test would be worth 20 percent of your overall grade in the course.

3. Find your overall grade

Find your overall grade in the class. Take the number of points you have earned on every assignment and add them together. Then divide this number by the number of possible points in the entire course. So if, for instance, you have earned 850 points total in a class where there were 1,000 possible points, your grade percentage in that class is 85. This is considered a "B" grade on an average grade scale.

1. Calculate average per category

Calculate your average for each weighted category. When grades are weighted, it means your teacher has assigned a specific percentage of your overall grade to each grade category.

For this example, suppose your test grades are worth 50 percent, your homework grades are worth 25 percent, and your classwork grades are worth 25 percent of your overall class grade.

• The first step is to calculate your average score in each of these categories.
• Add up the total points you earned in each category and divide by the total points possible in each category.

2. Multiply Grade by Weight

Multiply the average grades you have for each category by the weight of that category.

For this example, multiply your test score average by .50, your homework average by .25 and your class work average by .25. Suppose you earned 85 percent average on your tests, 90 percent average on your homework and 95 percent average on your class work, then the numbers you would have would be 42.5 (tests), 22.5 (homework) and 23.75 (class work).

• To calculate the weighted test score, multiply 85 percent by 0.50 to yield 42.5. Follow the same rationale in the formula to calculate the weighted scores for homework and class work.
• To calculate the weighted homework score, multiply 90 percent by .25 to yield 22.5.
• To calculate the weighted class work score, multiply 95 percent by .25 to yield 23.75.

3. Add final figures together

Add the final figures together to determine your overall grade. If you add 42.5 with 22.5 and 23.75, you get 88.75. This means that your overall grade in this class is 88.75 percent, which is a high B average.

If your teacher gives out letter grades instead of numerical grades, ask her to tell you the numerical equivalent of your grade. If you earn a B on a project, for instance, you need to know if she will use an 82 or an 88, or any other number, to calculate that grade as part of your overall average.

Marks Percentage Calculator

Use this test mark to percentage calculator to easily calculate the percentage given one or more test grades (marks) and the maximum possible number of marks. If you enter marks from multiple test exams or test tasks, they will be summed before the percentage calculation. Suitable for all school and college level exams.

    How to calculate percentage of marks?

To find the percentage of marks only basic arithmetics with proportions is required. If it is a single mark, first divide the mark by the maximum possible mark and then multiply by 100 to get the percentage. If there are multiple marks involved, first find their sum total, then proceed as if it is a single mark and divide by the maximum total marks out of which these marks were obtained. Multiply by one hundred at the end to convert to percent. You can do this by hand, following the formulae below, or by using our mark percentage calculator above.

For example, if an exam has a single section and the maximum score is 25, for a student who scored 18 enter 18 in the first input field and 25 in the second, then click "Calculate". If an exam has three sections, or a student is scored on three separate subjects, enter the three obtained scores separated by spaces or commas like so "80 60 90" and then enter the maximum score they could have obtained, e.g. 300 if the score ceiling on each test is 100.

    Marks to percentage formula

In the simplest case we have just a single exam and therefore a single test grade to work with. In this case the calculation to convert marks into percentage is straightforward by following this formula:

Mark Percentage = Scored Mark / Test Maximum x 100

"Test maximum" corresponds to the "Out of ... marks" input field in our test grade percentage calculator.

If an exam is scored in separate test sections, or if you are calculating the percentage from several separate exams, then the following formula is applicable:

Mark Percentage = Sum of Scored Marks / Test(s) Maximum x 100

The sum is calculated in the usual way using simple algebra. Our percentage calculator of marks handles that for you automatically.

    Test marks to percentage - practical examples

First, a simple example with a single test. Let's say a student scored 85 on an exam with a maximum mark of 100. Plugging the numbers into the above formula, we get:

85 / 100 = 0.85 x 100 = 85% so the test percentage is 85%.

Now for a more complicated example of converting a score to percentage where there are two tests or two test sections that are being scored. If a student scored 92 points on the first exam and 88 points on the second one, and the total marks they can get on both tests is 200, what is the percentage that the student scored? To calculate this, we first sum up the two marks and then apply the equation as usual:

(92 + 88) / 200 x 100 = 180 / 200 x 100 = 0.90 x 100 = 90% so the overall percentage mark is 90%.

The table below shows the test grades on a given examination and their corresponding percentages assuming a maximum mark of 200.

All test percentages in the table are computed using this exam percentage calculator.

    How to calculate the average percentage score for an entire class

The above method can be expanded to any number of marks, including calculations for the percentage scored by a whole class of students on a given test material, or even across class subjects which can be useful to educators as a measure of success. For example, with 20 students in a class, enter the 20 marks obtained in the "Scored" calculator field (separate by spaces or commas) and then the maximum possible score (e.g. 20x40 = 800 if each student can get a maximum of 40 points) in the "Out of" field.

The grade calculator can help you estimate your overall grade based on your component marks . The tool deals with three types of grading systems prevalent in the US – it's a letter grade calculator, a grade percentage calculator, and a point grade calculator.

In the text, you can learn how to use the grading calculator and how to determine an overall grade without it. Find out how to calculate weighted grades, how to calculate grade percentages, and more.

You can use the tool as an unweighted or weighted grade calculator , and set the particular grading scale your teachers use.

🔎 Check our weighted average calculator if you want to learn more about the weighted average.

Prefer watching rather than reading? We made a video for you! Check it out below:

We divided the tool into three parts – a letter grade calculator, a grade percentage calculator, and a point grade calculator. You can enter up to 20 marks (new fields will appear once you fill in the last row displayed).

The weights are, by default, set to 1. Leave them as they are if you want to calculate an unweighted average. If your grades have weights, set them accordingly. If the weights are percentages, enter them in decimal form ( 1 = 100%, 0.5 = 50%, 0.2 = 20% , etc.).

Schools and universities in the United States use different grading scales. You can read more about them using Omni's GPA calculator . You can specify the thresholds used by your teachers in the Advanced mode (click the button below the grading calculator). By default, the calculator uses this common grading scale :

Some schools don't use "+/-". In this case, the most popular grading scale looks like this:

For a quick estimation of the final grade, our final grade calculator should be a valuable tool.

The letter grading system is common in the US. Let's see how to use the letter grade calculator :

If your school uses a different grading scale than the one described in the first paragraph , go to the Advanced mode and set the grading scale.

Set the Grades type to "Letters."

In the first field, choose the grade you got from the first assignment, test, exam, or subject.

If your grades have weights or credits, enter the weight of the first grade. You can enter a natural number, a decimal, or change the unit to a percentage. If the weight is a percentage, you can input its decimal form (e.g., 0.5 for 50%).

If you're calculating the unweighted average (all grades are equally important), ignore the letter grade calculator's weight fields.

Proceed this way with all your marks. New rows will appear as you fill in the last field.

Your overall grade will appear at the bottom of the letter grade calculator.

If you want to clear all the fields and make the calculator grade again, click the circular arrow icon to reload it.

To use the grade percentage calculator :

Set the Grades type to "Percentage".

Type in the percentage result of your first test, task, or subject. Underneath, enter the weight or credits given for the grade. Ignore this field if your teacher doesn't use weights.

Continue to enter the percentage grades of all your assignments, tests, etc., along with their weights. New rows will appear once you fill the last field.

The grade percentage calculator will display the average of your marks. It'll also tell you the equivalent letter grade. The calculator is based on the default grading scale , so change it in Advanced mode if you need to.

To use the point grade calculator :

Set the Grades type to "Points".

Enter how many points you got from the first task, assignment, or subject. Then type in the maximum number of points you could get for the task.

Set the weights (credits) if applicable.

Enter the rest point grades, along with both maximum points and weights.

The point grade calculator will show you how many points you achieved in total and what was the maximum you could have got (your score/max, while ignoring the weights). You'll also see the equivalent percentage and letter.

The formula that lets you calculate weighted grades is:

(g₁ × w₁ + g₂ × w₂ + … + g n × w n ) / (w₁ + w₂ + … + w n ) ,

• "g" stands for "grade"; and
• "w" stands for "weight".

This is what the weighted grade calculator uses.

The formula answers the question "how to calculate weighted grades." We could translate it into some instructions :

• Multiply all your grades by their weights.
• Sum the numbers from step 1.
• Sum the weights.
• Divide the sum from step 2 by the sum from step 3.

The weights tell you how important the grade is. Imagine you got a grade B with a weight of 2 and an A with a weight of 5. It's as if you got two Bs and five As. Let's find the overall grade from these marks.

First, we need to convert letters to numbers . "A" stands for 4, and "B" equals 3. Now that we know this, let's use the formula described above and calculate the weighted average of all grades:

(3 × 2 + 4 × 5)/(2 + 5) = 26/7 ≈ 3.71

We translate the result back to the letter : 3.71 is an "A-".

In the case of percentage grades, we use the same formula as for letter grades.

Example : you're finishing a year and want to calculate your overall grade for a class. You got 67% for an essay worth 15% of the grade, 75% for a midterm exam worth 35%, and 72% for a final worth 50%.

Let's apply the formula. Remember to convert the weights from percentages to decimals . If you need help, our decimal to percent converter may come in handy. The weights add up to 1 (100%), so you can skip the denominator part of the formula.

67% × 0.15 + 75% × 0.35 + 72% × 0.5 = 10.05% + 26.25% + 36% = 72.3% ≈ 72%

Your final grade is 72%, which we may denote as C-.

In the case of point grades, we can convert them to percentages and assign a letter equivalent if needed. We can use the following formula for point grades :

p 1 /p 1,max × w₁ + p 2 /p 2,max × w 2 + … + p n /p n,max × w n ) / (w 1 + w 2 + … + w n ),

• p – Points acquired on a test;
• p max – Maximum number of points on a test; and
• w – Weight of a grade.

To estimate your test grade, you can also check our test grade calculator .

Example : I got 70/100 points on the first test, 46/100 on the second one, and 177/200 on the third one. The first test constitutes 30% of my overall grade, and so does the second one. The third one is worth 40%. Calculate my grade.

Let's substitute our values into the formula :

grade = (70/100 × 30% + 46/100 × 30% + 177/200 × 40%) / (30% + 30% + 40%)

Usually, when we express weights in percentages, they add up to 100% (or just one in decimal notation). In these cases, you can skip the denominator part of the formula (since dividing by one doesn't change the result).

We convert the percentages to decimals :

grade = (70/100 × 0.3 + 46/100 × 0.3 + 177/200 × 0.4) / (0.3 + 0.3 + 0.4) .

We convert the points (grades) to percentages , and the weights add up to 1:

grade = (70% × 0.3 + 46% × 0.3 + 88.5% × 0.4) / 1 .

We add up the numbers and round the result:

grade = 21% + 13.8% + 35.4% = 70.2% ≈ 70% .

We assign a letter :

70% is a C- .

What's a 75 in letter grade?

A 75% in letter grade is equivalent to a C , which is considered a passing grade. Generally, a C is somewhere between 70 and 79 percent.

Some schools use letters with "+/-", meaning that a C- is 70-72 percent , a C is 73-76 percent , and a C+ is between 77 to 79 percent .

How do I calculate my final grade in percentage?

To calculate your final grade in percentage:

Add up the grades you've received on all the assignments, tests, and projects.

Divide this by the total points possible.

Multiply your result by 100 to express it as a percentage.

For instance, suppose your scores are 15/20, 18/20, and 12/20:

The total points you got are: 15 + 18 + 12 = 45

When dividing this by the total possible points of your course ( 60 ), you get: 45 / 60 = 0.75

In percentage terms, your final grade is: 0.75 × 100 = 75% .

Missing Grades Make the Math More Complicated

The reason we need these calculators, 6 ways to evaluate student progress, grade calculators: useful tools to show you what you've accomplished and help plan your next move.

A weighted grading calculator can be a lifesaver for students who need to know where they stand at any point in the grading period. These convenient programs save time and give students and teachers quick, accurate information. But what is it they do? This article will investigate what functions grade calculators perform, how they operate, and why we have grades in the first place.

Where You Are and How to Get Where You're Going

The three calculators above can help teachers and students answer urgent questions about grades in seconds. First, the Grade Calculator computes a weighted average for any course, accepting both number and letter grades.

In addition, the Final Grade Planning Calculator displays the grade needed on outstanding assignments to reach a target final grade. Also, the Final Grade Calculator determines what a student needs to score on their final exam to reach their target final grade.

Compared to the normal average, a weighted average requires more calculations. When you figure out a weighted average, the many numbers you use are given varying weights or values in relation to one another. This phenomenon occurs in most high-school and college courses, where different assignment types are worth different percentages of the final grade. A course grade calculator makes finding weighted averages quick and accurate.

In addition, many students become concerned near the end of a quarter, semester, or year. They often worry that they will not get a good grade, but they can rely on a Final Grade Planning Calculator to tell them how to perform to reach their desired goal.

Similarly, students often need to achieve a specific score on their final project or exam to get the desired grade. In this case, a Final Grade Calculator lets them know how hard they must work to get where they need to go.

Suppose a grading period is over and all grades are accounted for. In that case, a student can use the Grade Calculator to ensure the teacher made no mathematical errors. In this example, the student enters each assignment, grade, and weight into the calculator.

After clicking "Calculate," the Grade calculator provides a numerical and letter grade.

Average Grade: 87.7 (B+)

Provided there are still grades or categories outstanding, enter the target final grade and the weight percentage weight of the outstanding assignments.

After hitting "Calculate," the Final Grade Planning Calculator will display the current weighted average and the score required on outstanding work to achieve the desired final grade.

• Average grade: 85.0 (B).
• A grade of 95.0 is needed for the remaining 30% of tasks to ensure a final grade of 88.

When all grades other than the final exam are accounted for, enter the current weighted average grade, target grade, and final exam weight in the Final Grade Calculator. Click the Calculate button.

• Your current grade: 79
• The grade you want: 85
• Your final is worth: 35%

The Final Grade Calculator will display the final exam grade necessary to attain the desired final grade.

Result You will need a grade of 96.1 or higher on the final.

Weighted averages include numbers with different abilities to skew the average—thus the term "weighted." Unfortunately, many students (and some teachers!) don't understand how to calculate grades using weighted averages because they require more calculations than simple ones.

Suppose you're attempting to figure out your grade in a class where different assignments are worth varying percentages of your final grade. In that case, you might need to determine a weighted average. Whether the sum of your weights equals 1 (or 100%) will affect the method you employ.

It's Pretty Simple When You Have All the Data

To calculate a weighted average where the total weights equal 1, multiply each grade by its corresponding weight and add them all up. Rendered mathematically: g1(w1) + g2(w2) + g3(w3), and so on, where g is each grade and w is the corresponding weight. Of course, most syllabi list weights as percentages, so you will need to convert them into decimals first. For example, 25% equals 0.25; therefore, 100% equals 1.

The math is slightly different when some grades are missing, and the total weights equal less than one. This happens when you use the Final Grade Planning Calculator to determine your current weighted average and the score needed on the outstanding work to get the final grade you want.

Mathematically, you would figure out the weighted average the same way. However, you need to take the sum of each grade (weight) and divide it by the total weight of the known grades (in decimal form).

The formula would be Σgw/Σw where Σgw is the sum of each grade (weight) and Σw is the sum of all weights in decimal form.

The complexity of these calculations makes a weighted grade calculator a lifesaver for students.

Grading is a comparatively recent invention. Since 1785, students at Yale have been receiving the Latin equivalents of the words best (optimi), worse (inferiores), and worst (peiores). So, Yale was the first university in the United States to assign grades.

Before that, American colleges followed the Oxford and Cambridge models, which required frequent attendance at lectures and a weekly dialogue between the student and their proctor, both in person and in writing.

When the proctor or panel of other professors thought the students had shown an appropriate grasp of the subject, the course was declared complete. The faculty gave no grade. A prospective employer could only compare a student's qualifications through reference letters.

Universities experimented with a wide variety of systems during the 19th century. For example, Yale used scales ranging from four to nine points. The professors at Harvard experimented with 20 and 100-point scales before deciding that grouping students into five classes, with the lowest class failing the course, was the best they could do.

To assist professors in evaluating students, William and Mary public research University in the U.S. used the categories: "orderly, accurate, and attentive" or "they have learned little or nothing."

Because of the significant increases in immigration and the emergence of regulations requiring compulsory attendance, schools were overcrowded at the beginning of the 20th century. As a result, teachers and administrators needed an effective, standardized method for testing and grading many pupils. These circumstances naturally led to the nationwide standardization of school grading.

Our calculators use the percentages and letter grades common in the U.S. However, there are many other ways to assess student progress. Here is a quick list of common grading alternatives:

• A percentage ranging from 0% to 100%.
• Letter Grades with Variations (A, C+, B-).
• Standard-Based. Students receive marks relative to specific knowledge in the curriculum.
• Mastery-Based Grading. Students have the time to master a skill before moving to another.
• Narrative-Based Grading. Students receive lengthy written feedback about their performance in class.

It may seem that the student grading system has been around forever. However, before the 20th century, the grading systems we now know did not exist.

We still worry about how to determine our grades when each type of assignment has its own "weight." We wonder what we need to get on the final exam to pass.

Our grade calculator can't give you the knowledge to handle every assignment. But he can reassure you by telling you where you are and what results you need to achieve.
