Grade calculation

This is the norm for the grades obtained in each course, taking into account the course credits. Assessment frameworks vary in many countries or even in schools. This calculator recognizes letter grades as well as numeric inputs. These letter grades are deciphered into numerical values as shown below.

Letter Grade Calculation

Convert a percentage or score into a letter grade using a grading scale. For instance:
A+ = 4.3 grade points
A = 4 grade points
A- = 3.7 grade points
B+ = 3.3 grade points
B = 3 grade points
B- = 2.7 grade points
C+ = 2.3 grade points
C = 2 grade points
C- = 1.7 grade points
D+ = 1.3 grade points
D = 1 grade point
D- = 0.7 grade points
F = 0 grade points

- 90-100% = A
- 80-89% = B
- 70-79% = C
- 60-69% = D
- Below 60% = F
- Example: If a student scores 85%, their letter grade is B.
Each of these methods depends on the grading policies and scales defined by the educational institution.

Calculating a student's grade depends on the grading system used, which can vary by school or institution. Here are some common methods:

Percentage-Based Grading

- In this system, each assignment, test, or activity has a score (usually out of 100).
- The student’s grade is the percentage of points they earned divided by the total points available.
- Formula:

Weighted Grade Calculation

- When different components (tests, assignments, projects) have different weights, calculate each component's contribution separately, then add them up.
- Formula:

{Final Grade} = (Weight of Component 1 X Grade of Component 1) + (eight of Component 2 X Grade of Component 2) + ........

- Example: If tests are 50% of the grade, assignments 30%, and projects 20%, and the student scored 80% on tests, 90% on assignments, and 70% on projects:

{Final Grade} = (0.5 \times 80) + (0.3 \times 90) + (0.2 \times 70) = 40 + 27 + 14 = 81\%

Grade Point Average (GPA)

- In systems where letter grades (A, B, C, etc.) correspond to grade points (e.g., A = 4.0, B = 3.0), calculate GPA by averaging these points based on course credits.
- Formula:

- Example: For three courses with grades A (4.0) in a 3-credit course, B (3.0) in a 4-credit course, and C (2.0) in a 3-credit course:

How to Calculate Grade using VBA Procedure in excel

calculate grade using vba in excel

To calculate grade using vba in excel We need to calculate Grade with college students examination numbers and We have an excel sheet. if you havnt prepare excel sheet with students numbers then prepare it first

Microsoft VisualBasic Applications

By opening the Microsoft VisualBasic Applications window you can access the VisualBasic (VBA) environment in Excel 2007-2013

To begin with, ensure that the VBA DEVELOPER tab is seen withinside the toolbar in Excel 2007. .

The DEVELOPER tab is the toolbar that has the buttons to open the VisualBasic (VBA) editor.
To display the Developer tab, click on on FILE withinside the menu and pick out Options beginning from the drop menu.

At the factor the Excel Options window indicates up, click on, after that click on at the Customize Ribbon at the left.

Under the list of Customize Ribbon Main Tabs on the right, Select VBA Developer checkbox . Then click on the OK button.

Now from the toolbar Select the VBA DEVELOPER tab at the top of the screen. Then in the Code group, click on the VisualBasic option.

Presently the Microsoft VisualBasic VBA for Applications editor ought to seem and also you insert your VisualBasic VBA code.

From menu pick insert button then click on Module.

The Applications editor of Visual Basic ought to to expose up then insert function Grade.

Function grad(alpha As Double)
If alpha = 4 Then
grad = "A+"
ElseIf alpha < 4 And alpha >= 3.4 Then
grad = "A"
ElseIf alpha < 3.4 And alpha >= 3.1 Then
grad = "B+"
ElseIf alpha < 3.1 And alpha >= 2.8 Then
grad = "B"
ElseIf alpha < 2.8 And alpha >= 2.4 Then
grad = "B-"
ElseIf alpha < 2.4 And alpha >= 2.1 Then
grad = "C+"
ElseIf alpha < 2.1 And alpha >= 1.8 Then
grad = "C"
ElseIf alpha < 1.8 And alpha >= 1.5 Then
grad = "C-"
ElseIf alpha < 1.5 And alpha >= 1 Then
grad = "D"
End If

End Function

After entereing the code then write procedure name called Grade then click save button and then close visualbasic editor.

Now in cell O5 write formulation for N5, to calculate GPA open the following link. How to calculate GPA
after that in cell P5 enter formula (= gpa(N5)) to calculate grade.
