In
a hybrid grading system, we use a combination of both absolute and relative
grading systems.
-
The
two highest grades and the lowest grade are earned and the grades in between
are awarded.
-
To
earn A grade, student has to secure >= 85 and < 90 aggregate marks.
-
To
earn A+ grade, student has to secure >= 90 aggregate marks.
Once highest and lowest grades are
identified, the remaining grades are then awarded by plotting the histogram of
number of students (Y axis) and marks (X axis) and identifying the cluster of
students. These clusters of students are identified based on gaps and dips in
the histogram.
The
list of letter grades and its connotation are shown in table 1.

Semester
Grade Point Average (
SGPA) calculation :
A
SGPA will be computed for each
semester. The SGPA will be calculated as follows:
where
Ci =
Credit for the course
GPi = Grade Point obtained for the course and
n = Number of subjects registered for the semester.
cumulative Grade
Point Average (CGPA) calculation :
A
Cumulative Grade Point Average (CGPA) will be computed for every student at the
end of each semester. The CGPA would give the cumulative performance of a
student from the first semester upto the end of the semester to which it refers
and calculated as follows:
Where
'm' is the total number of semesters under consideration. Ci the total number
of credit registered for during a particular semester and Si is the SGPA of
that semester. Both SGPA and CGPA will be rounded off to the second place of
decimal and recorded as such.
