The method for calculating your final grade for a given discipline depends on certain variables. To complete this task, you will need to know the coefficients assigned to each assignment, test, exam and participation. The best way to collect this information is to look at the syllabus that your teacher or teacher gave you. Once you have identified the number of assignments and their weightings, you will no longer have any difficulty in calculating your grade.

Steps

Method 1 of 4: Manually calculate an unweighted final mark

Calculate Your Final Grade Step 1

Step 1. Enter your notes

For a given term, write down the points you got for your homework, tests, etc. Sometimes you will be able to do this online by using a rating center, such as “Blackboard”. Often times you will have to go through all of your proofs. Write your notes in a column on a piece of paper, which you will use as a reference.

If your participations or presentations are included in the final grade, you should ask your teacher to communicate your results in these subjects to you

Calculate Your Final Grade Step 2

Step 2. Write all the top marks

These are the highest marks a student can achieve. To do this, you will need to review the guidelines for the rating system. Teachers employ various systems to determine average marks, but the two main ones are expressed either in points or in percentages. Whatever the situation, enter all the maximum scores in the second column next to the points you have obtained.

  • In a points system, you can get a maximum per discipline. The points are also distributed by assignment. For example, a subject can be graded out of a total of 200 points. So, if you have to hand in four assignments in this subject, each of them will have a maximum mark of 50 points (4 × 50 = 200).
  • In a percentage system, each assignment will be worth a certain percentage of your final grade. The sum of all percentages is 100%. For example, you might have four homework assignments each worth 25% of the final grade (4 × 25 = 100).
  • In these examples, each assignment has the same weight throughout the course, although the number of assignments varies.
Calculate Your Final Grade Step 3

Step 3. Add the sum of the two columns

This operation is valid as long as your homework is marked in percentage or in a total of some other kind. Calculate the first column and enter the result at the bottom. Add the numbers entered in the second column and mark the total at the bottom.

  • Suppose you have a total of 5 activities consisting of 2 exams scored out of 20 points each and 2 tests scored out of 10 points each. The last activity being an assignment graded on 5 points.
  • The total number of points that can be obtained in this course is calculated as follows: 20 + 20 + 10 + 10 + 5 = 65.
  • Add up your scores. Suppose you scored 18/20 on your first exam, 15/20 on your second exam, 7/10 on your first test, 9/10 on the second, and 3/5 on your assignment.
  • The total of the marks you obtained is equal to: 18 + 15 + 7 + 9 + 3 = 52.
Calculate Your Final Grade Step 4

Step 4. Calculate your final grade

To get this percentage score, divide your total points by the total points you can earn. In other words, divide the number at the bottom of the first column by the number at the bottom of the second.

Calculate Your Final Grade Step 5

Step 5. Multiply the decimal number by 100

To have a more practical figure, you need to convert the decimal result to a percentage. To do this, multiply it by 100. You can also shift the decimal point two notches to the right.

  • 52/65 = 0, 8 or 80%.
  • To move the decimal to the right, add a few zeros like this: 0, 800. Now shift it two notches. Which gives you 080, 0. Remove the unnecessary zeros and you get 80. This means that your final grade in the course is 80.
Calculate Your Final Grade Step 6

Step 6. Determine your final alphabetical grade

To do this, you will need to understand the grading scale applied in your class. Some schools use letters (example: A, B, B-, etc.), while others prefer numbers, for example: (4, 0); (3, 5); (3, 0), etc. These scales are defined according to the maximum percentages that can be obtained in a subject.

They also vary according to the schools, some of which use averages with the + or - sign. Others adopt 10-point ranges (for example: a mark between 90 and 100 is A, if it is between 80 and 89 it is a B, etc.). Some institutions use a range of 7 points (for example: 97 to 100 = A, 93 to 96 = A-, 91 to 92 = B +, etc.). How to grade may also depend on the teacher

Method 2 of 4: Manually calculate a final weighted mark

Calculate Your Final Grade Step 7

Step 1. Identify the weighting of the scores

Indeed, some of them may have a higher percentage in the final grade. For example, participation can count for 30%, 4 tests for 10% each and a final exam for 30%. Thus, you will find that the final exam and participation have a more significant impact on the final grade, as they are worth 3 times as much as each test.

  • Check your program or ask your teacher to tell you the weightings of the different grades.
  • In high school, it is common for advanced classes, such as upgrading classes, to receive more points than regular classes. If you are trying to calculate your final weighted mark, you will need to know the coefficient assigned to each activity.
Calculate Your Final Grade Step 8

Step 2. Multiply your score by the weighting percentage

To make this easier, you can first enter your grades and maximum grades in two separate columns. Then you multiply each note by its coefficient. Write the products in another column.

For example, if the share of a final exam in the final mark is 30%, and you have obtained 18/20, it suffices to multiply this mark by 30, which gives you: 30 × (18/20) = 540/600

Calculate Your Final Grade Step 9

Step 3. Add up the weighted scores

After multiplying each note by its weight, add up the points you obtained and the maximum points. Divide the sum of your points by the sum of the points you can get.

  • Here is an example. Weighting by assignment: 1er duty = 10%, 2e duty = 10%, 1er test = 30%, 2e test = 30%, participation = 20%. Your notes: 1er duty = 18/20, 2e duty = 19/20, 1er test = 15/20, 2e homework = 17/20, participation = 18/20.
  • 1er homework: 10 × (18/20) = 180/200.
  • 2e homework: 10 × (19/20) = 190/200.
  • 1er test: 30 × (15/20) = 450/600.
  • 2e test: 30 × (17/20) = 510/600.
  • Your participation: 20 × (18/20) = 360/400.
  • Your total score: (180 + 190 + 450 + 510 + 360) ÷ (200 + 200 + 600 + 600 + 400) or 1690/2000 = 84.5%.
Calculate Your Final Grade Step 10

Step 4. Compare the percentage obtained on the rating scale

After calculating your final weighted mark, you can compare it to your class's rating scale. Such a scale might look like this: A = 93-100, B = 85-92, etc.

Often, teachers and professors round off marks to the nearest percentage. So your 84.5% will become 85% for the purposes of finding your final alphabetical grade

Method 3 of 4: Determine an unweighted final grade with a worksheet

Calculate Your Final Grade Step 11

Step 1. Create a new spreadsheet

To do this, use your operating system's spreadsheet program. For better organization, type a title at the top of each column. Reserve the first column for the name of the activity. In the second column, write down the marks you obtained. The third column will be reserved for maximum points.

For example, your entries could be: the name of the activity, the grade obtained, the maximum grade

Calculate Your Final Grade Step 12

Step 2. Enter your data

Fill in the 1D column by writing the names of the different activities. Then enter your points in the 2e column and maximum scores in the 3e. If the score is expressed as a percentage, it means that the maximum score is 100.

Calculate Your Final Grade Step 13

Step 3. Add the sum of the 2e and the 3e column.

In the first column, write "total" under each activity name. Then, interval to the right in the same row to place yourself directly below the last note you marked. Type sum, then =, then open a parenthesis. You will have something like: sum = (. Then select the first note and move the cursor down to cover all the notes in the column. Then release the mouse button and close the parenthesis. You will get something like: sum = (B2: B6).

  • Repeat the operation with the 3e column, that of maximum points.
  • You can also enter the range of cells you want to sum. For example, if you need to add the values ​​contained in cells B2, B3, B4, B5, and B6, write sum = (B2: B6).
Calculate Your Final Grade Step 14

Step 4. Divide your total score by the total number of points

Stay on this line and go to 4e column. Type = and open a parenthesis: = (. Then select the total grades you achieved during the semester. Type a forward slash and select the total maximum points. Close the parenthesis: = (B7 / C7).

Press enter. Thus, the total will appear on the screen

Calculate Your Final Grade Step 15

Step 5. Convert the decimal number to a percentage

This operation is very easy to do on a spreadsheet. Go to the next column. Type the = sign and open a parenthesis. Select the decimal note you just calculated. Then type an asterisk, then 100 and close the parenthesis. You will get something like: = (D7 * 100).

To get the result, just press enter

Calculate Your Final Grade Step 16

Step 6. Determine your position on the rating scale

Just compare your final percentage score to the scale in question. Knowing the total percentage of all your activities, you are able to identify the corresponding alphabetical note by making a simple comparison (eg A, B-, D +, etc.). If it is a numeric scale, for example: (3, 75), (2, 5), (1, 0) etc., you will need to multiply the decimal number by the maximum score.

For example, if your grade is 0.82 and you are rated on a scale of 4, as is usual, multiply the decimal number by 4. This will give you your final grade expressed in l appropriate scale

Method 4 of 4: Determine a final weighted mark with a worksheet

Calculate Your Final Grade Step 17

Step 1. Create a new spreadsheet

To do this, use your operating system's spreadsheet program. For better organization, type a title at the top of each column. Reserve the first column for the name of the activity. In the second, write the marks you obtained, and in the 3e column, mark the maximum points that can be obtained.

  • For example, your columns can be the following: the name of the activity, the score obtained, the maximum score, the coefficient and the weighted score.
  • Enter your details. At this stage, you can just enter the names of the activities, the marks obtained, the maximum marks and the coefficients.
Calculate Your Final Grade Step 18

Step 2. Multiply your scores by the corresponding coefficients

Thus, you will get the percentage of each of your performances. Suppose your quarterly exam grade is worth 30% of the final score and its value is 87, you will need to open a parenthesis first and select the grade cell in question. Then type an asterisk and 30%. You will have something like this: = (B2 * 30%).

Calculate Your Final Grade Step 19

Step 3. Add up your weighted scores

Choose a cell to display your final weighted score. Use the sum function as before. Type the = sign, then sum. Then open a parenthesis and select the cells containing your notes. Close the parenthesis and press enter. The expression will look like this: = sum (B2: B6).

Calculate Your Final Grade Step 20

Step 4. Determine your position on the rating scale

Just compare your final percentage score to the scale in question. Knowing the total percentage you got for all weighted activities, you are able to identify the corresponding letter by making a simple comparison with an alphabetical grade scale (e.g. A, B-, D +, etc.) or a series of numeric notes: (3, 75), (2, 5), (1, 0), etc.

Advice

  • Check that you have entered all of your notes.
  • Always save your work. Classify your assignments, tests and exams to use correct grades in your calculations. This action will help you later if you dispute a grade with your teacher or professor at the end of the semester.
  • Use the grades on your report card. Do not use the semester note. Limit yourself to periodic notes.
  • If you want to determine your periodic grade instead of your final grade, all you have to do is do the math using the grades you got for your homework, tests, projects, etc.
  • The above instructions should be reproduced precisely. For example, if the instruction is = sum (B2: B6), you should write it unchanged.
  • Here are some examples of rating scales used around the world. The entries below represent the alphabetical mark, the percentage mark and the weighted final mark, respectively, separated by commas.

    • A, 0-100, 4, 0
    • B, 80-89, 3, 0
    • C, 70-79, 2, 0
    • D, 60-69, 1, 0
