How to Estimate your final Course Grade

your final course grade

Several factors influence how you calculate your final grade for a class. You must know how course assignments, tests, quizzes, and participation grades are weighted when determining your final grade to complete this task.

The best way to find this information is to consult the syllabus that your teacher or professor gave you. Calculating your final grade should be easy once you’ve determined the number of assignments, the weighted value of each project, and your score on each project.

Calculating Your Non-Weighted Final Grade Manually

1. Write out your score:-

Throughout the term, keep track of your grades for each assignment, quiz, and homework.

This information is often gathered for you online, such as in a system like Blackboard. You’ll have to go over your graded work from time to time. To make it easier to remember, write them all down in one column on a piece of paper.

If things like Participation or debate are weighted as percentages of your final grade, you may need to inquire about your grade on this section with your teacher or professor.


2. Write out the total possible points:-

The grading system is explained in the syllabus. Teachers use various methods to calculate final grades, but points and percentages are the most common. In the second column, next to the score you got, write out the total possible points.

  • In a points-based system, there is a maximum number of points you can receive in a class. Each assignment is allocated a certain number of points. For example, a course may have 200 total points available, divided into four assignments worth a maximum of 50 points each (4×50=200).
  • Each assignment would be worth a certain percentage of your grade in a percentage-based system. The sum of these percentages equals 100 percent. For instance, suppose you have four assignments due, each worth 25% of your grade (4×25=100).
  • Even though the numbers vary, each assignment in these examples is worth the same overall weight in your course.

Add up both columns

You should do this even if your tasks are graded on a percentage scale or a different total. Add the first column’s numbers together and write the total at the bottom. Add the numbers in the second column together to get the total.

Assume you have a total of five graded course activities. Two of these activities included 20-point examinations. Two of these activities were ten-point quizzes each. The final activity was a five-point assignment.

  • The sum of 20+20+10+10+5 equals 65. The total number of points available in the class is shown here.
  • Add up your points now. Consider the following scenario: you received an 18/20 on your 1st exam, a 15/20 on your 2nd exam, a 7/10 on your 1st quiz, a 9/10 on your 2nd quiz, and a 3/5 on the single assignment.
  • 18 + 15 + 7 + 9 + 3 = 52. This is the total number of points you received during the course.

Calculate your average grade

To get a percentage grade, divide your total points earned by the total number of points available. To put it another way, divide the number below the first column by the number below the second column.

Multiply the decimal number by 100

It would help if you converted the decimal to a percentage to get a more standard grade. Multiply the decimal by 100 to get the answer. Another option is to move the decimal point two places to the right.

  • 52/65= 0.8 or 80%
  • Add two more zeroes to move the decimal point two places to the right, as in 0.800. Shift the decimal two places. The result is 080.0. Take away the zeros, and you’re left with 80. This indicates that you received an 80 in the class.

Determine your letter grade or grade point equivalent (GPA)

To determine your final grade, you’ll need to know your class’s grading scale. Some schools use letter grades (such as A, B, B-, and so on), while others use a point system (ex. 4.0, 3.5, 3.0, etc…).

These scales are all based on percentages that correspond to the total number of points that can be earned in a class.

  • Depending on your school, these scales may also differ. Some schools, for example, may assign plus/minus grades while others do not. A ten-point scale may be used by some (e.g., anything between 90-100 is an A, anything between 80-89 is a B, etc.). Others would use a seven-point scale (for example, 97-100=A, 93-96=A-, 91-92=B+, and so on). This could also change based on your professor’s preferences.

Calculating Your Weighted Final Grade Manually

1. Identify how grades are weighted.

This means that specific grades account for a more significant portion of your overall grade. For instance, your grade could be 30 percent participation, four quizzes worth 10% each, and a final exam worth 30%. The tricky part is figuring out how your participation grades and final exam affect your grade, especially since they are three times as important as each quiz grade.

  • Check your syllabus or inquire about the weighting of grades with your teacher.
  • Advanced classes, such as Advanced Placement classes, are often given more “quality points” than average courses in high school. Make sure you understand how each course is weighted before attempting to calculate your GPA.

Multiply the weight percentage times your scores

To make things easier to keep track of, separate your grades and the total points available in separate columns. After that, multiply each number by the weighted amount. Make a new column to keep track of these figures.

  • For example: If a final exam is worth 30 percent of your total grade and you received an 18/20, multiply 30 by 18/20. (30 x (18/20) = 540/600).

Add up your new numbers.

When you multiply each score by its weighted percentage, add the total number of points you earned and the total points possible. Divide the sum of all your weighted points by the sum of all the by the total weighted number of points. Divide the total sum of all of your weighted points from the total weighted number of points.

  • For example:- Assignment 1 weights 10%, Assignment 2 weights 10%, Test 1 has a weight of 30%, Test 2 has a weight of 30%, and Participation has a weight of 20%. Your findings are as follows: Test 1= 15/20, Test 2= 17/20, and Participation= 18/20, Assignment 1= 18/20, Assignment 2= 19/20.
  • Assignment 1: 10 x (18/20)= 180/200
  • Assignment 2: 10 x (19/20)= 190/200
  • Test 1: 30 x (15/20)= 450/600
  • Test 2: 30 x (17/20)= 510/600
  • Participation: 20 x (18/20)= 360/400
  • Total Score: (180+190+450+510+360) ÷ (200+200+600+600+400), or1690/2000 = 84.5%

Compare the percentage score to the grading scale

Compare your final percentage grade to your class grading scale now that you’ve calculated your final percentage grade while accounting for the weighted assignments. For instance, A=93-100, B=85-92, etc.

  • Teachers and professors often round up scores to the nearest percentage point. To assign a final grade, your 84.5 percent will become 85 percent.
