Grading System :
(a) Conversion of marks to Grades :
Actual marks secured by a group of candidates are converted into Relative
Percentile (R) before conversion into Relative Letter Grades. The maximum
Actual marks (i,e. Highest mark) (M) secured in a particular Group is converted
into 100% and other actual marks (A) secured by the students of the same groups
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 marks is not less than 30%
(b) Conversion Table for Relative Percentile into Letter Grades and Grade points.
Range of Relative

(C) Conversion of Grades of CGPA & CPI :
Grade point average (GPA) is used as a numerical survey of academic
achievement, First, Grades are assigned to points in a 10 points 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 course 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. The same of honour points in a given semester is then divided by
the total number of credits.
Example :
Course No. Course/
Paper
Credit Grade Point Honour
Point
Chem-401 12 A 10 120
Chem-401 12 B 8 96
Chem-420 12 C 6 72
Chem-60X 8 D 4 32
Chem-430 Laboratory
work
16 A 10 160
60 480
Grade point average (GPA) = 480 / 60 = 8.0
Cumulative Performance Index (CPI):
The final result of a four Semester Course is expressed as the average Grade
points obtained by the student in the entire course:
CPI = (CPA) Sem-I+ (GPA) Sem-II (GPA) Sem-III+GPA Sem-IV / 4
(d) Conversion Formula: for m Grades to P.C. of marks for Humanities and Social
Science:
For CGPA upto 9.5 : (5XCGPA)+20
For CGPA above 79.5 : (65XCGPA) -550
So, for c lass-I minimum CGPA be 8
For class –II minimum CGPA be 5
For other subjects / disciplines :
For CGPA upto 9.00 : (10 X CGPA)-5
For CGPA above 9.00 (15 X CGPA)-50
In order to qualify for a P.G. degree a student must secure CGPA of minimum 5.0
(equivalent to 45% marks).
