 # Grade Point Average Scale

Introduction :

GPA or grade point average scale is an important measure as it signifies the long term performance of a student. This reflect the student’s ability to perform consistently good or bad. Generally master’s programs requires a minimum GPA scales of 3.0 and a minimum of 3.3 is required for a Ph.D. Grade points of different universities for a particular grade may vary from each other as Grade point average scale is not standardized, so it is hard to compare students of different universities using this scale.

## Calculation of Grade Point Average Scale

Step 1: First calculate the Grade points for each subject depending on the grades obtained.

Step 2: Calculate the total no. of grade points obtained in all the subjects.

step 3: Calculate the total number of credit hours for all the subjects.

Step 4: Now Grade point average  = (Total grade points)/ (total credit hours)

Here is an example which explains the calculation of GPA in detail:

## Example for Grade Point Average Scale:

Let the the subjects be Biology, Statistics, Geography, and Maths. And the grades earned by a student be B,A,C,B respectively for each subject. Calculate Grade point average of the student if the grade points for each grade A,B,C,D are 4 ,3, 2,1 respectively?

Solution:

Grade points for  Biology    =  credit hours`*` grade points = `3 *3` =`9`

Grade points for  Statistics   = credit hour`* ` grade points  = `2*4` =`8`

Grade points for  Geography = credit hours`*` grade points  = `5*2` =`10`

Grade points for  Maths       = credit hours`* ` grade points   = `1*3` =`3`

Total grade points  = sum of grade points earned for each subject

= `9+8+10+3`

=`30`

Total credit hours           = sum of credit hours of each subject

= `3+2+5+1`

=`11`

 Subject Credit hours grade Grade points Biology 3 B 9 Statistics 2 A 8 Geography 5 C 10 maths 1 B 3 Total credit hours: 11 Total grade points :30

So  Grade point average     `=` total grade points earned )/(total credit hours

`=30/11`

` =2.72`

GPA of the student is `2.72`
