Grade calculator grade

While grades continue to shape important decisions in the life of a student, calculating grades has time and again ben a perplexing question for them. While there are many systems used by the teachers across the world, there are certain similarities that continue to be the criteria for everyone to compute them. One should definitely know about the process and procedure for calculating the grades so that one can put in the required hard work and strive to bridge the gap and strive for what’s the best for him or her.

The Types of Grading System

There are three grading system types:

  • Weighted system
  • Points System
  • Formula System

Points System:

Items are given a value in points. Categories are then calculated by the sum of the points of their child items. Therefore, the final grade calculates the total number of points of all the grade items.

Total Points:

In this calculation method, the students’ cumulative grade is based on the total points earned divided by the total points attempted. Select this option if the cumulative grade is based on straight points, and you do not take into account the type of assignment when calculating the grade.

Total Points

Homework:
1) 86/100
2) 92/100

Test:
1) 84/100
2) 45/50

Quiz:
1) 79/100
2) 90/100

Project:
1) 94/100
2) 80/100

Cumulative= 650 points out of a possible 750 so 650/750= 86.67%

Total Points with Weight: 

In this calculation method, the students’ cumulative grade is based on the total points a student earned, divided by the total points attempted within each assignment type. The assignment type cumulatives are then averaged together based on their weights. Select this option if the cumulative grade is based on something like 30% homework, 40% quizzes, and 30% exams, but each assignment within those categories is worth varying points.

Total Points w/ weight

Homework=30%:
1) 86/100
2) 92/100
=178/200 which is 89 or 89%

30% (weight of this Assignment Type) of 89 “points” = 26.7

Test=20%:
1) 84/100
2) 45/50
=129/150 which is 86 points OR 86%
20% of 86 = 17.2

Quiz=10%:
1) 79/100
2) 90/100
169/200 OR 84.5%
10% of 84.5 = 8.45

Project=40%:
1) 94/100
2) 80/100
174/200 which is 87 points OR 87%
40% of 87 = 34.8

Then you add the Points of Each Type together:
26.7
+17.2
+8.45
+34.8
=87.15% which is the Cumulative Grade for the Term

Note: Test 2 has a Max point of 50, therefore the grade needs to be double, the grade of 45 x2 is 90 since Max points must equal 100 it is counting this score 2x. If using Percentages, it is best to always have Assignments be 100 points.

How are How grades calculate in Gradebook?

So if you are looking forward to calculate your grades then calculating a course grade can be easily done using the number of points earned or scored and the total score. The Gradebook automatically calculates a course grade based on the scores. Gradebook only reflects the graded scores of the student’s assignments and not the ungraded ones. It may not be absolutely true for it doesn’t take account of the ungraded assignments. If you want to include your ungraded assignments then you need to enter a zero as the input value in the required field. Gradebook subtotals are calculated by taking the number of points a Student earned divided by the number of points available to be earned.

If the Gradebook has Weighted Categories, after determining the subtotal for the Category by taking points earned out of points available, the Category weights are used to come up with the Subtotal.

Gradebook subtotals are calculated by taking the number of points a Student earned divided by the number of points available to be earned.

If the Gradebook has Weighted Categories, after determining the subtotal for the Category by taking points earned out of points available, the Category weights are used to come up with the Subtotal.

For example:

A Gradebook has four entries with the following values for one Student: 80/100, 70/100, 40/50, 6/10. The Student’s final grade will be calculated by adding points earned (80+70+40+6), then dividing by points available (100+100+50+10). So, in this case, the Student’s grade is 196/260, or 75%.

In a Simple setup a Gradebook that does not use Categories–all entries are averaged to find the final grade.

To Conclude:

The Gradebook calculates the user’s average by dividing the total points earned by the total possible points of all grade Items.Justbys selecting one of the three options of grading from above doesn’t give you the end result of your grades. There are other steps that you have to follow in order to get the result. The following formula does the needful:

Formula: sum(assignment grade * assignment factor) / sum(maximum points * factor) = Total cumulative grade
