(a) Conversion of marks to grades: Actual marks secured by a group of candidates in a particular
paper are converted into Relative Percentile (R) before conversion into Relative Letter Grades. The maximum Actual narks (i.e. Highest mark)(M) secured in a particular paper is converted into 100% and other actual marks (A) secured by the student of the same group are converted to the Relative Percentile.
R=(100/M)XA where, R=Relative Percentile
M=Maximum(Highest)marks in the class.
A=Actual marks of a student who passed i.e. if the actual Mark is not less than 40%.
(b) Conversion Table for Relative Percentile into letter Grades and Grade points.
Range of Relative percentage Letter Grades Grade point
90-100 A 10
75-89 B 8
60-74 C 6
45-59 D 4
40-44 E 2
If Actual marks is below 40%. F
*F means fail and must be repeated in the coming semesters.
c)Grade point average (GPA) is used as a numerical survey of academic achievement. First ,Grades are assigned to points in a 10 point scale as follows:
A=10 points , B=8 points, C=6 points, D=4 points, E=2 points ,F= 0 points.
Secondly ,the hours of credit for each courses are multiplied by the grade point value to determine the honour points.The honour points are then added for all the courses / papers in a semester is then divided by the total no of credits.
