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`

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`
