No matter whether you are a student in High School, Intermediate, Graduate, or Post Graduate, calculating your final grade with percentages is a very important task. It plays an important role in gaining your final degree certificate irrespective of which degree you are. However, there are many ways and many steps to be followed while you are calculating your final grade with percentages. Now, let us see some ways to calculate and steps to be followed to calculate your final grade with percentages.

The ways of calculating the grades will be different in schools, colleges, and Universities. First, let us learn how to calculate the final grade with a percentage at the school level.

In some schools, only the marks scored by you in your respective subjects will be taken into consideration while calculating the final grade. And whereas in other schools, the management will consider some extracurricular activities like sports, assignments, and projects.

## Case-1:

So, if your school considers only the subject marks for your final grade. Then, you should consider the following method to calculate the final grade with percentage.

The first thing you need to do is to add all the marks you have secured in each subject. Then add the total marks of all subjects. Now, you need to divide the secured marks by the total marks. Here, you will obtain the total grade. Next, you need to calculate the percentage. To calculate the percentage with the grade, you have to multiply the grade by 100. The result you will get is the percentage of your final grade. This is how you can calculate the final grade with percentage.

Let us see an example of this:

The following are the marks you have obtained in your school in each subject.

Language1: 60 marks

Language2: 70 marks

Mathematics: 80 marks

Biology: 66 marks

Physics: 65 marks

Chemistry: 96 marks

Botony: 87 marks

Social studies: 95 marks

Consider the above eight subjects as an example for calculating your final grade with percentage. Assume that the total marks of each subject are 100. And the overall marks will be 800. Now, let us see how we will calculate the grade and percentage using these marks.

Adding all the secured marks of each subject, you will get a score of 619. This will be your final grade. Divide this score by 800. You will get 0.773… Now, when you will multiply 0.77 by 100, you will get 77% which is your final grade percentage. This is how you will calculate the grade in this case.

## Case-2:

The schools in which the management will also consider some extracurricular activities like sports, assignments, and projects in addition to the academic subjects come under this case. Let us see the methods and steps they follow to give you the final grade with a percentage.

When there are other activities like assignments, quizzes, and sports in your grade. The total marks you obtained from all of those activities will be together considered Internal marks. Therefore, the marks secured by you in the regular academic exam conducted by your school are known as External marks.

Hence, you can calculate your final grade with percentages by calculating the total grade and percentages of internal and external marks.

You can use addition and division to calculate your grade on an individual assignment or test, and your progress in class to get your final class grade. You can also multiply assignments if there are any weighted grading systems or class scores by the assigned weight. So that you can calculate your final grade in an easy way.

Let us close the topic of calculating your final grade at the school level. Now, you will see how to calculate your final grade with percentages at your college or university level. I guess you are so curious to know about it.

## Calculate Final Grade at College/University Level

Calculating the grade when you are in college or university is completely different from calculating the grade when you are in high school. The way of calculating the grade with percentages by the management in colleges and universities will be completely unique.

When you try to calculate your final grade, you should first know what a GPA is. A GPA is defined as “Grade Point Average”. It can be obtained by calculating the arithmetic average of all the grades obtained for all courses respectively. taking into account the time spent on them, including the final grade for the exam work.

However, the GPA scale will be different in different regions. The final grade can vary from 0.0 to 5.0 according to European countries. And the final grade varies from 0.0 to 4.0 according to the American state. When you apply to different universities after completing college, you need to provide your final grade in GPA to the universities. By observing and verifying your GPA and percentage, the admissions committee will decide whether to accept your application or not.

Even the method of calculating a grade in a particular university is different and may vary sometimes. Because a few numbers of universities calculate the grade for the last 3 years of study only. And few other universities will ask you to calculate your final grade in specific subjects only. Therefore, only one method or formula is not applicable in all cases and for all grades.

You need to multiply the number of hours spent by you on a course by its rating to calculate the final average grade. As we already discussed, the final grade is based on a 4-point grading system, that is used in many countries like the United States and other countries. Therefore, you need to calculate the average score or grade as shown below:

First, you need to convert the grades into a numerical grading system such as A=4, B=3, C=2, D=1, and F=0. Then, you need to multiply the grade by the number of hours for each course. Now, find the total number of hours spent on all classes. The next step is to divide the result that is obtained from the first step by the result that is obtained from the second step that you will come to know in the below lines.

The following is the formula for calculating the final grade with respect to hours:

GPA = (grades*hours spent)/total hours

Now, look at the following example to calculate your final grade.

Assume that you got the following grades:

Biology (100 hours) – A;

Mathematics (200 hours) – B;

Physics (70 hours) – A;

Computer science (80 hours) – C;

Chemistry (50 hours) – B.

First, you need to convert the grades into the numerical grading system as per the following logic:

A=4, B=3, C=2, D=1, F=0.

Biology (100 h.) – 4

Mathematics (200 h.) – 3

Physics (70 hours) – 4

Computer Science (80 hours) – 2

Chemistry (50 hours) – 4

Now, you should multiply the numerical grades by the number of hours for each and every course and add them together:

4 * 100 + 3 * 200 + 4 * 70 + 2 * 80 + 4 * 50 = 1,644

The next thing you need to do is to put the total number of hours for all academic disciplines taken together:

100 + 200 + 70 + 80 + 50 = 500

Finally, you should divide the grade total (1,644) by the total number of hours (500):

1644/500 = 3.3

Your GPA = 3.3

This is the method you need to follow to calculate your final grade at the college or university level. Now, you will come to know some steps to be followed while calculating your final grade with percentages.

## Step – 1:

This step helps you to determine the grading policy while you are calculating the final grades. Because understanding the grading policy is important before you start calculating percentage grades. This step helps you to define how each category of tasks is weighted.

For example, assume that your professor can weigh 35 percent of the total score on homework, 40% on assignments, and 25 percent on quizzes.

## Step – 2:

This step helps you to calculate the category averages for percentages of grades scored by you in your class. If you want to calculate grades in percentage, you must calculate the averages of their categories. For this, you just need to add up all of your scores in each category and then divide by the number of tasks for this category. You might be a little confused but a simple example will be very helpful.

For example, assume that there are 5 quizzes with scores of 89, 76, 99, 85, and 90. When adding up all the scores, you will get the final score of 439. Now, you have to divide the total sum by 5 and you will get the quiz average of 87.8 percent.

## Step-3:

You will use this step to convert the weighted grade percentages of your final grade. In this step, you will get a percentage grade by converting mark percentages to a decimal value. For this, you need to divide the percentage you got in the previous step by 100. For example, assume that the quizzes are weighted 25, and then the decimal value is 0.25

## Step – 4:

This is the final step that is used to determine the total final grade. With this step, you will finally know how to calculate grades with percentages. Here, you should add all the results of each category you’ve got in the previous steps to find out your total grade.

For example, assume that you got a score of 21.95 for quizzes, a score of 38.79 for homework, and a score of 24.65 for your assignments, then your total grade will be 85.39 percent.

I conclude that you need to follow the above methods and steps to calculate your final grade with percentages.
