-# @Description: Gpa is Grade point average, which is use to determine the student academic pointer
-#               based on the value of the grade he/she acquired in single semester, where as cgpa is cumlative
-#               grade point average is to calculate the total credits and total grade acquired in
-#               his/her entire academics. Here i have determined to use grade scale of two values
-#               5.0 and 10.0, many other academics may have different grading system.For a different grades and   #               their grade values, You can change the value in method called getGradeData.For any bug report #               contact at above email-address
